Metals rule the world
Metals are shiny, malleable, and fusible hard materials readily conducting heat and electricity. The mobility of electrons within the bulk solid accounts for their peculiar properties useful for technological applications. Different metals also allow mixing to form alloys, possessing properties suited to applications.
Matter we see on the earth is constituted of 93 chemical elements, of which 66 have metallic properties. Prehistoric man identified metals incidentally and exploited them for advantage using empirical techniques. Later, chemists studied metals for curiosity, and their findings paved the way for numerous applications that transformed the world.
Metals rule the world. They profoundly shaped human civilisation, advancing technology and therefore social structure in distinctive leaps. For that reason, the historical periods after the Neolithic are often named after metals: copper, bronze and iron. Metals, subsequently introduced through the efforts of chemists and engineers, opened new eras of technology.
Today, we see things made of aluminum everywhere, but no one saw aluminum until 1825, when the metal was first extracted by the Danish physicist Christian Oersted. Four decades later, an electrolytic method was developed to obtain aluminum from the ore bauxite. Thereafter, the metal previously considered to be the most precious, owing to its resistance to extraction via conventional methods, reached the status of a versatile metal superior to iron and copper in many applications. Today, it would be hard for us to live without aluminum. Indispensable aluminum artifacts are part of our routine.
Uranium, the heaviest metal on earth, progressed our understanding of matter and the cosmos, changed the political landscape and remains as an ample source of energy.
Now we are witnessing the dawn of another era defined by a series of metals known as rare earths. Crucial sectors of advanced technology indispensably rely on these metals. Rare earth metal processing continues to be a monopoly of China, producing nearly 90 percent of the global demand. Recently, other industrial nations have expressed concerns regarding secure supplies of rare earth metals, because of the possibility of trade embargoes and sensitive political issues.
Copper, Bronze and Iron Ages
Metallic chemical elements are abundant in the earth’s crust. However, a few occur as free metal. Of these copper, silver and gold were the only ones known to the ancients. Melting in fire and the malleability of copper, unlike stone and wood, fascinated the prehistoric man who innovated tools out of the metal. The Copper Age began independently in several regions of the world around 5500 – 3000 BCE. Implements made from copper eased the construction of dwellings and agriculture, expanding settlements that turned into states regulated by law and order. States originate when a group of people working collectively exceeds a critical size.
The discovery of bronze, an alloy of copper and tin, provided better metal artifacts, as bronze is harder and more durable than copper. Tin does not exist in nature as the elemental metal but is readily liberated when the ore is incinerated in charcoal fire. The benefits of the improved quality of the alloyed metallic products stood disproportionately high. The Bronze Age flourished, advancing all spheres of human activity, until it abruptly ended around 1200 BCE. The reason why the Bronze Age collapsed remains an unresolved puzzle in history. Possibly the dwindling supply of tin constrained the production of bronze. Tin ores are scarce. Even today, the short supply of tin affects industries involving its usage.
After the collapse of the Bronze Age, there had been a dark period lasting for several centuries. Being unable to maintain itself, civilizations declined economically, partly destroying the established infrastructure. Famine, war and other calamities were common in this period.
During the Bronze Age, smiths meddled with iron and methods of mining were available. Yet the form of iron they extracted was brittle and inferior to bronze in toolmaking. The shortage of metal tin prompted them to explore alternative arts of smelting iron. Finally, methods of making steel evolved. The techniques alloyed iron with a small percentage of carbon to derive steel. Durable and strong steel tools facilitated clearing a larger acreage of land for agriculture and the erection of more secure large buildings. Just like other technical breakthroughs, the advent of steel influenced society negatively as well. It allowed sharper dangerous weapons used to inflect cruelty on fellow human beings and animals.
Iron is still the most widely used metal and no other metal would replace it. Nevertheless, historians assume that the Iron Age was closed around 550 BCE, when bronze was almost completely replaced by steel in the making of tools.
Aluminum Age
After iron, the next most widely used metal in recent times is aluminum. Although aluminum stands topmost in the list of relative abundance of metals in the earth’s crust, the elemental metal does not occur naturally and resists extraction by conventional methods. A sample of metallic aluminum was first prepared in 1825. Subsequently, costly methods produced kilogram quantities sold at exorbitant prices. Those days, aluminum happened to be the most precious metal. Only kings and emperors could afford to possess aluminum artifacts. The Emperor of France, Napoleon III, owned an aluminum dinnerware set, occasionally used to serve exceptionally distinguished guests. Other honored visitors got gold plates, spoons and forks.
An electrolytic process for the extraction of aluminum in the late 1800s changed the situation. Aluminum production and its use as a structural material escalated exponentially. Good electrical conductivity and lightweight reduced the cost of electricity transmission by replacement of copper cables by aluminum. Current global aluminum production exceeds 60 million metric tons a year.
Uranium: key that opened the door to explore the nature of matter, source of energy and cause of conflicts
Uranium impacted the world intellectually, technologically and politically. It is the heaviest metallic element naturally existing on earth. In 1896, French physicist Henry Becquerel discovered uranium emanating radiation spontaneously (radioactivity). Subsequent work by Marie Curie, Ernest Rutherford and others culminated in the elucidation of the atomic structure and the discovery of quantum mechanics. And later a deep understanding of the nature of fundamental forces and particles. Fission of uranium atoms to less heavier atoms with liberation of large quantities of energy was first observed in 1938. Seven years later, the first atomic bomb was tested and months later they were used in war. The atom bomb altered the political landscape of the world. Despite the risk of weapons development, uranium awaits as a ready promise to solve fossil-dependent energy production. Today, 10 percent of the global energy supply is derived from uranium. The estimated global uranium reserve is sufficient to power the world for a century.
Rare earth metals
‘Rare earth metals’ is a common phrase in news headlines these days, poised as a technological and political issue. We see things turned out of common metals; iron, copper and aluminum – and understand their essential importance. Rare earth metals are not visibly manifested that way and the laity are largely unaware of their existence and importance. What are rare earth metals? Why are they important?
The occurrences of chemical elements in the earth’s crust in the concentrated forms as minable minerals are determined by their chemistry. Electrons in the atoms of chemical elements distribute around the nucleus as shells. The number of allowed electrons in the outermost shell, dictated by laws of quantum mechanics, fixes the chemistry of the element. Rare earths represent a series of seventeen metallic elements having a similar outer shell electronic structure. They are not so rare but found diluted and mixed owing to the similarity of chemistry. Chemists identified and separated them lately. For that reason, they were named rare earths.
Rare earth metals are used in small quantities but essential to advanced technologies and are referred to as vitamins of modern industry. Hi-tech devices contain crucial components that incorporate rare earth metals. Smartphones, television, medical instrumentation, electric vehicles, wind turbines, aircraft engines, etc., have parts made of rare earth metals or their compounds. Countries strive hard to reduce fossil fuel consumption by optimizing renewable energy sources. Wind turbines require powerful permanent magnets made of rare earth neodymium and dysprosium alloys. Other specialized magnets that resist heat require the rare earth samarium. Colored LED lights use the rare earths yttrium, europium and terbium. The demand for rare earths will increase with developments in AI hardware, robotics and quantum technologies.
Processing of rare earth minerals offers several technical and environmental constraints that require specially designed chemical engineering procedures. Material resources and scientific know-how, largely a monopoly of China. Other technically competent nations who neglected the rare earth sector for decades are concerned about the availability of rare earth metal for their industries including weapons development.
Iron, copper, aluminum, uranium and rare earths stand out as the metallic elements that impacted human civilization most. There are dozens of other metals driving modern technology, without which we would not enjoy the comforts we have.
Metals we have in Sri Lanka
Sri Lanka extracted metallic iron and made implements as far back as 3000BC. Around 100 CE, Sri Lankans invented an extraordinary process for making quality steel – intricately designed blast furnaces utilizing the blow of the monsoon winds. The Samanalawewa archeological project identified 41 iron smelting furnaces. The ore had been gathered from local deposits scattered throughout the Northern region. Currently, commercially viable extraction of iron from locally available ores may not be unprofitable because Sri Lanka has no coal to derive coke required to reduce the iron oxide. We must be vigilant about future iron extraction technologies using hydrogen or direct electrolysis. Alternatively, iron can be used as a hydrogen storing agent. The oxide ore is reduced to iron using hydrogen and stored fine grains of iron reacting with steam to generate hydrogen.
Archaeological evidence indicates copper technology existed in Sri Lanka as far back as 4th. BCE. Sri Lanka Geological Survey discovered the Seruwila iron-copper deposit in 1971 – a source from which copper was mined. If copper was mined from the Seruwila deposit thousands of years ago. Why can’t we do it today? The average Seruwila ore contains about 0.6 percent copper and 30 percent iron – copper sufficiently high for commercial exploitation. Recently, the International Energy Agency warned that a global copper shortage is on the horizon and by 2030 mines could meet only 80 percent of the projected global demand. It would be prudent for Sri Lanka to conduct studies to develop processes for the extraction of copper from the Seruwila deposit. We should go out-of-the- box and innovate new ideas.
The metallic treasure of Sri Lanka resides in mineral sands. They accumulate along the beaches as the result of a natural separation of heavier and lighter grains. There are two categories of valuable metals in our mineral sands. So-called transition elements: titanium in Ilmenite and rutile, zirconium and hafnium in zircon, and rare earth metals (cerium, lanthanum, neodymium, samarium, promethium, gadolinium, yttrium) in monazite. Monazite also contains radioactive heavy elements uranium and thorium.
Ilmenite is used to obtain the widely used paint base titanium dioxide and the metal titanium essential for aerospace and marine engineering. Today, physically separated ilmenite is exported without conversion to oxide losing considerable profit. One conversion process (the older) requires sulfuric acid and the other, chorine and coke. We have no raw materials to produce sulfuric acid and coke. There is a newer process that uses hydrochloric acid (HCl). This acid can be manufactured in Sri Lanka using salt. In fact, Paranthan Chemicals- Chlor- Alkali Industry in the Northern Province made HCl years ago. Sri Lanka needs to resume Chlor-Alkali industry immediately to produce vital chemicals: chlorine, hydrochloric acid and sodium hydroxide. Alternatives apart from established processes to beneficiate ilmenite would not be impossible. Researchers and students should understandingly meddle with chemical substances for curiosity.

Bronze age tools
Currently, Sri Lanka Mineral Sands Limited exports 100 metric tons of monazite a year. The recipient countries use the ore primarily to produce rare earth metals needed for the hi-tec industry. Radioactive bye products, thorium and uranium are probably stockpiled. Monazite is a phosphate mineral containing 19 metals in different proportions. The reason why so many elements are bonded to phosphate is that they all have similar chemistries. Therefore, their separation is also cumbersome and poses environmental issues. The crucial techniques kept trade secrets. Should Sri Lanka begin chemical processing of monazite? There are two routes of monazite processing, acid and alkaline, depending on the chemical initially used to crack the mineral. The former uses sulfuric acid and the other sodium hydroxide. If Chlor- Alkali industry is established, Sri Lanka would be able to process monazite via the alkaline process and alkali neutralization carried out with HCL. It would be premature for Sri Lanka to jump into rare earth chemical processing immediately. What we need at this juncture is preparedness, feasibility studies and analysis of commercial prospects in a global context.
Thorium, a metal abundant in Sri Lanka, could be the ultimate solution to the energy crisis and decarbonization of the world to ensure a livable environment. The cleanest and greenest energy source is nuclear. Modern technology has largely addressed safety and radioactive disposal issues. Unlike uranium, thorium is not fissionable but convertible to a fissionable isotope of uranium by neutron bombardment. Thorium contains 200 times more energy than uranium. The feasibility of thorium reactors was first proved by the Oak Ridge National Laboratory, United States, in 1968 and abandoned a few years later. The interest in thorium reactors has been rekindled recently and vigorous developmental work pursued in the United States, China, India, Europe, Canada, Japan and Indonesia. Thorium is special to Sri Lanka. The thorianite containing a high percentage of thorium was first discovered in Sri Lanka by Ananda Coomaraswamy in 1903. Sri Lanka thorianite was used by the pioneers of atomic physics to uncover deep secrets of nature. Lord Rutherford (discoverer of atomic structure), in his famous address to the Canadian Astronomical Society, titled “Cosmical aspects of radioactivity “said: “I have some crystals of a new mineral thorianite found in Ceylon.” It contains 12 percent uranium and 70 percent thorium. In the early 1900s tons of thorianite collected from gem gravel and stream sediments in Sri Lanka were shipped to Europe. Today, no effort is made to separate thorianite from discarded gem gravel. This valuable mineral should be collected and stockpiled. Sri Lanka’s nuclear energy plans should also focus on thorium for future energy prospects.
Thousands of years ago, Sri Lanka was foremost in metal extraction (copper and iron) and workmanship. Today we are poor in metallurgical science, engineering and industry. The main cause is our weakness in chemical innovations. Chemistry is taught and learned in tuition classes as an essential to enter the medical and engineering streams in our universities. Writing papers to earn promotions and ranks: a purpose of chemical research.
The illustrious chemist Humphery Davy, who extracted seven metallic elements for the first time, learned chemistry by home experimentation while working as an apprentice to an apothecary. To initiate chemical industries in the local context, we need people who have chemistry in their blood.

‘Building Blocks’ of early childhood education: Some reflections
In infancy and childhood is laid the groundwork for an integrated personality in the making, in preparation for adaptation to the outside world. The malleability of the nervous system [neuroplasticity] due to its extensive growth during early childhood, considered to be the critical period for learning, offers the potential to bring about lifelong benefits in terms of social, emotional and intellectual development.
My goal in this brief article is to reflect on the essential elements [‘building blocks’] of education in early childhood which help to lay the foundation for positive outcomes in later life. It is intended to encourage conversation amongst the general readership of this important topic, especially the parents of young children, as learning begins at home.
Critical Period for learning
Early childhood usually covers the age range from infancy to about eight years of age, during which period most of the brain growth takes place. The prefrontal cortex of the brain responsible for higher cognitive functions [e. g. planning, decision making etc.] continues to mature into the mid-twenties. That isn’t to say that learning processes could not continue throughout life.
Current Community Attitudes towards Education
Let us first examine the current public attitudes towards education in general. Proficiency in reading, writing, math and science are regarded as the core academic literacies on which all other learning rests, and on which future success in life depends. The Arts and Humanities, a group of disciplines that study aspects of human society and culture, are placed lower in the hierarchy in the academic curriculum and are often considered supplementary. Their value in enhancing human ideals is often ignored. In a technologically advancing world we live in, the contribution of the study of the arts and humanities towards boosting the economy is brought into question.
The above attitude has created a highly competitive, exam driven, and hence stressful, academic environment for our children in their formative years. There are excessive demands placed upon them to achieve academically, exacerbated by parental pressure – overt or covert. Attendance at paid ‘tuition classes’, after hours, to supplement learning at school is considered essential to gain higher grades at exams, in order to be competitive in entering tertiary institutions and in enhancing career prospects. The love of learning is lost.
Many children find no time for reflection, or to read outside the curriculum to broaden their understanding about life. There is a perception in the community of a decline in literacy and sensibility in the young and their tendency to lean towards much less civilising forms of entertainment and communication, which is at the root of most of our social ills, compounded by the economic ills that currently plague us. Alarmingly, a recent survey by the College of Community Physicians of Sri Lanka has revealed that over 200 adolescents have committed suicide in 2024, which they, reportedly, attribute to their indulgence in social media. But at the heart of it is the breakdown of social order resulting in a lack of ‘meaning’ in life, as once postulated by the renowned French Sociologist, Emile Durkheim.
Family Milieu
The developing child requires the provision of certain environmental conditions, based on common principles, to complement the innate biological drive which we call instinct. Of vital importance is the family milieu, its stability and its ability to meet the child’s emotional needs. From an emotional point of view, the child needs to feel safe, and experience the contentment in the parent’s inter-relationship, in order to set the ground for learning. In addition, it helps for the parents to model the love of learning and of knowledge through communication in words and in actions.
In an ideal world, a child’s parents and teachers ought to be equally committed towards helping the child develop a love of learning. In some instances a teacher must shoulder most of the work – for instance, when parents are busy making a living or have had a limited education themselves.
Enrichment Strategies
Let us reflect on some of the enrichment strategies in early childhood education which would bring about a balance in the curriculum.
The Arts
“Engagement of children in the arts has the power to console, transform, welcome, and heal. It is what the world needs now” [Yo Yo Ma, Cellist]
The arts are commonly used as enrichment strategies in Early Childhood Education. They include music, dance, drama, and Visual and literary arts. The strengths developed through the arts during the early formative years have the potential to enhance other spheres of learning, and performance in later life. By eliciting emotions in the listener, the arts, as both Aristotle and Freud asserted, has the capacity to be therapeutic by being cathartic.
Music
Neuroscientists have shown that, due to the plasticity of the brain in young children, music training tended to enhance the auditory [hearing] pathways in the brain, and hence, the development of phonological awareness [responsiveness to contrasting sounds]. Phonological awareness is considered to be an important precursor to reading skill and the ability to rhyme. In addition, ‘Music is the language of emotions’, encouraging children to gain awareness of their own emotions in addition to making aesthetic judgements.
Drama
Research studies show that enacting stories in the classroom in comparison to dramatic performances on stage by children have several beneficial effects such as better understanding of the stories enacted and the appreciation of new stories. In addition, such classroom performances of stories enriched oral language development and reading skills, including an eagerness to read, and surprisingly, even writing skills.
Visual Arts
Engagement of children in visual art involves much more than learning the techniques of drawing and painting. Long periods of engagement in the craft provides a framework for enhancing thinking skills – to be more focussed and persistent in one’s work; to enhance the power of imagination; to generate a personal viewpoint or express a feeling state; and to encourage the child to reflect on and to make a critical judgement of their own work. Similarly, by entering into a conversation with the children after encouraging them to look closely at a piece of art, tended to heighten their observation skills. There is evidence that these habits of mind acquired from the engagement of children in visual arts could be ‘transferred’ to other areas of learning, and stand in good stead in employment in later life.
Reading
According to the British neuropsychologist, Andrew Ellis, the brain was never meant to read, in terms of human evolution: “There are no genes or biological structures specific to reading.” Reading had to be learned, requiring the integration and synchronisation of several systems of the brain acquiring a new neuronal circuitry for the purpose – perceptual, cognitive, phonemic, linguistic, emotional and motor. Reading, as it develops, aided by an environment that lures the child to read would lead to further enhancement of the cognitive capacity of the brain – an important dynamic in childhood education.
The more young children, are read to, and are engaged in conversation that flows on from stories read [‘conversational reading’], the more they begin to love books, increase their vocabulary and their knowledge of grammar, and appreciate the sounds that words generate – evidently, best predictors of later reading interest and critical thinking. Conversational reading is a technique where the parent or educator engages with the child in a conversation while reading a book, asking open-ended questions to encourage active participation and deeper comprehension, eg. entering into a dialogue about the story while reading it together.
In addition, reading enhances the child’s self-worth and personal identity [emotional experience of reading].
What better way for children to be introduced to the world that they are to be part of than to be immersed in a story that is all about beings and the environment that surrounds them? What better way for children to learn about ideas and speech patterns, how people react and interact, and how dialogue reveals more about a person than what they say, and about interpersonal relationships. Sadly, children with reading disability have a greater tendency to develop emotional and conduct disorders needing remedial support.
Children’s Literature
It is claimed that appropriate works of children’s literature, read or enacted, help the developing children build empathy and compassion – desirable human ideals that can persist through to adult life – by placing themselves in the shoes of fictional characters and simulating what the characters in the narrative are experiencing. One could argue that the same could be achieved in real life by interacting with others but does not have the advantage of having access to the inner lives of individuals as depicted in well-crafted fictional works.
There is no better way to convey moral instruction than by vicarious learning through reading. As the legendary Russian author, Leo Tolstoy, propounded in his popular monograph, ‘What Is Art?’, the value in a piece of literary art is to be judged by its ability to make the reader morally enlightened.
There is no better way for children, while gaining the aesthetic rewards of a narrative, to enhance their thinking and reasoning, generate creativity, and introduce them to a life rich in meaning.
“There are perhaps no days of our childhood we lived fully as those we spent with a favourite book…they have engraved in us so sweet a memory, so much more precious to our present judgement than what we read then with such love…”
[‘On Reading’, by Marcel Proust 1871-1922, French novelist and literary critic]
Children’s Poetry
We are endowed with a rich poetic tradition that extends as far back as the Sinhala language and its precursors. Over the centuries the lyrical content mirrored the changing socio-cultural and political landscape of our country. During the pre-independence era, there was a revival of lyrical output from men of vision aimed at enhancing the creativity and sensibility of the young, to prepare them for the challenges of a free nation, and enhance their sensibility. Foremost among this group of poets were: ‘Tibetan’ [Sikkimese] monk, Ven. S. Mahinda, Ananda Rajakaruna and Munidasa Kumaratunga. Their poems that lured the children most were about nature. Simple and well crafted, they were designed to draw children to the lap of Mother Nature, to admire her beauty and to instil in them a lasting imagery and a feeling of tranquillity. Ananda Rajakaruna’s ‘Handa’ [the moon], ‘Tharaka’ [Stars], ‘Kurullo’ [birds], ‘Ganga’ [The river]; Rev. S. Mahinda’s ‘Samanalaya’ [The Butterfly], ‘Rathriya’ [The Night]; Munidasa Kumaratunga’s ‘Morning’, which captures the breaking dawn, ‘Ha Ha Hari Hawa’ [About the Hare], are amongst the most popular. They are best recited in the original language as any attempt at translation would seriously damage their musical and lyrical qualities.
Narrative Art
Martin Wickremasinghe [1890-1976] was ahead of his time in recognising the importance of children’s literature and its positive impact on their psychosocial and intellectual development. He argued a case for establishing a tradition of children’s literature anchored in our heritage, and in keeping with the degree of maturity of the child; and that the work be presented in a simple and pleasurable form mixed with moral instruction in the right measure. He observed that a nation without children’s literature rooted in its heritage may face intellectual and moral decline. He asserted that children’s books should only be written by those who understood the developing mind.
In his publication, ‘Apey Lama Sahithyaya’ [Our Children’s Literature] Martin Wickremasinghe acknowledges past contributions to our children’s literature by prominent writers. Piyadasa Sirisena, Munidasa Kumaratunga, G. H. Perera and others transformed folk tales into prose and poetry for children. V, D, de Lanarolle was a pioneer in writing children’s stories for supplementary reading, naming his series, ‘Vinoda Katha’ [Pleasurable Stories]. Edwin Ranawaka translated children’s stories, from English to Sinhala, to suit the local readership. Martin Wickremasinghe’s own Madol Duwa, and G. B. Senanayake’s Ranarala and Surangana Katha were significant contributions to our children’s literature. Munidasa Kumaratunga took an innovative approach in producing ‘Hath Pana’ [Seven Lives], ‘Heen Seraya’ {Slow Pace], ‘Magul Kema’ [Wedding Feast] and ‘Haawage Waga’ [The Hare’s Tale] which gained immense popularity.
Despite the above, Martin Wickremasinghe argued that we have been slow in developing children’s literature of our own, although such a literary genre has been established in the west, for example, the Aesop’s Fables and the Fairy Tales of Hans Christian Anderson.
Aesop’s Fables, thought to have been narrated by a slave who lived in ancient Greece [whose identity remains obscure in history], have survived the test of time as a conveyor of values and virtues for children to reflect on, and to generate a conversation facilitated by their teacher. The allegorical tales, much admired by children [and adults!], are aimed at both entertaining and imparting moral wisdom with the use of animal characters having human attributes [Anthropomorphism] and their social interactions. The brief and lucidly told tales – 200 or more – laden with worldly wisdom, have the potential to generate a literate population, when introduced during early childhood. Let me remind you of few popular fables with their core messages: ‘The Hare and the Tortoise’ [Slow and steady wins the race]; ‘The Lion and the Mouse’ [No act of kindness, no matter how small, is ever wasted]; ‘The Cock and the Jewel’ [The value of an object lies in the eyes of the beholder]
The Fairy [fantasy] Tales of Hans Christian Andersen [1805-1875] continues to feed the imagination of growing-up children through his portrayal of unique and unforgettable characters – witches, beasts and fairies – with features of human life. The tales of the Danish master story-teller, translated into many languages, have gained universal appeal amongst children as he weaves his vastly entertaining stories such as Thumbelina, The Tin Soldier, and The Emperor’s New Clothes etc. based on fantasies with a lesson to convey. In addition to entertainment and instruction, his tales portray universal human conditions such as joy, sorrow, fear, pride, abandonment, resoluteness etc. and allow children to recognise their own feeling states, which the psychoanalysts believe is therapeutic.
The above shows that the east and west can meet on the ground of universal values, exemplified by the arts, and that human reason – the capacity of humans to think, understand and form judgement – is the true guide in life.
In sum, although reading, writing and mathematics in early childhood education are considered the core academic literacies on which other learning rests, and on which success in life depends, current research indicates that arts education through the development of certain habits of the mind could enhance academic achievement. It is thought that high arts involvement in children tend to augment their cognitive functions [eg. attention and concentration], thinking and imaginative skills, organisational skills, reflection and evaluation, which could be ‘transferred’ to other domains of the school curriculum, including science. This is in addition to the role the arts could play in enhancing interpersonal skill and emotional well-being, in conveying moral instruction, and in the exercise of empathy. As such, one could argue a case for a well-rounded system of education incorporating the arts to be introduced during early childhood.
I apologise for my ignorance in the Arts and Literature in Tamil.
Desirable Qualities of Educators
The above ideal could only be achieved through greater investment in training competent teachers in early childhood education. What ought to be the desirable qualities of an early childhood educator? It is my view that the teacher should a] have a good understanding of childhood development – physical, psychological and intellectual – and have the capacity to appreciate individual differences; b] possess ‘age-related’ conversational skills with the children – to listen and to allow free expression, with the aim of encouraging self-exploration of their work; c] have the ability to enhance children’s self-esteem while being able to set limits when necessary, within a framework of caring; d] understand the need to liaise with the parents; and, most of all, e] have a passion for educating children.
Educational Reform
Our nation is in need of a national policy on early childhood education as part of an overall plan on educational reform. It is expected that the powers that be will address a range of issues in planning of services: the inequity in access to Early Childhood Education; integration of early childhood education with the mainstream educational facilities; quality assurance and monitoring; and most importantly, greater investment in training of competent instructors in early childhood education, and creating opportunities for the teachers to be engaged in continuing education and peer review. It is hoped that the government will be able to create a framework for laying the groundwork for restructuring Early Childhood Education – a worthy cause in nation building.

Where stone, memory and belief converge: Thantirimale’s long story of civilisation
At the northern boundry of Anuradhapura, where the Malwathu Oya curves through scrubland and forest and the wilderness of Wilpattu National Park presses close, the vast rock outcrop of Tantirimale rises quietly from the earth.
Spread across nearly 200 acres within the Mahawilachchiya Divisional Secretariat Division, this ancient monastic complex is more than a place of worship. It is a layered archive of Sri Lanka’s deep past — a place where prehistoric life, early Buddhist devotion, royal legend and later artistic traditions coexist within the same stone landscape.
“Thantirimale is not a site that belongs to a single period,” says Dr. Nimal D. Rathnayake, one of the principal investigators who has been studying the area together with Ayoma Rathnayake and Eranga Sampath Bandara. “What we see here is continuity — people adapting to the same environment across thousands of years, leaving behind traces of belief, survival and creativity.”
Traditionally, the Thantirimale temple is believed to date back to the third century BC, placing it among the earliest Buddhist establishments in Sri Lanka.
The Mahavansa records that civilisation in this region developed following the arrival of Prince Vijaya, whose ministers were tasked with establishing settlements across the island. One such settlement, Upatissagama, founded by the minister Upatissa, is often identified as the ancient precursor to present-day Thantirimale.
Yet archaeology offers a deeper and more complex story. Excavations conducted in and around the rock shelters reveal that indigenous tribal communities lived at Thantirimale long before the rise of the Anuradhapura kingdom. These early inhabitants — likely ancestors of today’s Veddas — used the caves as dwellings, ritual spaces and meeting points thousands of years before organised monastic life took root.
“The rock shelters were not incidental,” Dr. Rathnayake explains. “They were deliberately chosen spaces — elevated, protected and close to water sources. This landscape offered everything prehistoric communities needed to survive.”
Over centuries, Thantirimale accumulated not only material remains, but also names and legends that reflect shifting political and cultural realities.
During the reign of King Devanampiyatissa, the area was known as Thivakkam Bamunugama, suggesting a Brahmin presence and ritual importance. Another strand of tradition links Thantirimale to Prince Saliya and Ashokamala, the royal lovers exiled for defying caste conventions.
Folklore holds that they lived in this region for a time, until King Dutugemunu eventually pardoned them and presented a golden butterfly-shaped necklace — the Tantiri Malaya — believed to have given the site its present name. Linguistic traditions further suggest an evolution from “Thangaathirumalai”, pointing to South Indian cultural influences.
Tantirimale also occupies a revered place in Buddhist memory. According to tradition, Sanghamitta Maha Theri rested here for a night while transporting the sacred sapling of the Jaya Sri Maha Bodhi from Jambukola to Anuradhapura. That brief pause transformed the rock into sacred ground, forever linking Tantirimale to one of the most powerful symbols of Sri Lankan Buddhism.
Among the most striking monuments at the site is the unfinished Samadhi Buddha statue, carved directly from a massive cube-shaped rock.
- A greater Portion of the Painted Surface of Cave NO.2
- Leatherback Sea Turtle
- The Crocodile or Land Monitor
Standing about eight feet tall, the statue bears a remarkable resemblance to the celebrated Samadhi Buddha of the Polonnaruwa Gal Viharaya. Guardian deities flank the central figure, while behind it a dragon pearl is supported by two lions — a motif associated with protection, sovereignty and cosmic balance. Dwarf figures decorate the seat, adding layers of symbolic meaning and artistic refinement.
“What is extraordinary here is the ambition of the sculpture,” says Dr. Rathnayake. “This was clearly intended to be a monumental work.” Excavations around the statue have uncovered stone pillars and evidence of a protective roof, indicating that artisans worked under shelter as they shaped the figure.
The statue’s incomplete state is most plausibly explained by the foreign invasions and political instability that marked the later Anuradhapura period. Stylistic features suggest that the work continued into, or was influenced by, the Polonnaruwa period, underscoring Thantirimale’s enduring importance long after Anuradhapura’s decline.
Nearby lies another monumental expression of devotion — the reclining Buddha statue, measuring approximately 45 feet in length. Unlike the Samadhi statue, this figure has been detached from the living rock and is dated to the late Anuradhapura period. Its scale and proportions closely resemble Polonnaruwa sculpture, reinforcing the idea of a continuous artistic and religious tradition that transcended shifting capitals and dynasties.
Yet the most ancient and fragile heritage of Thantirimale is found not in its monumental statues, but in two adjacent caves within the monastic complex. Their walls still bear the fading traces of prehistoric rock paintings dating back nearly 4,000 years. First recorded by John Still in 1909, these paintings were later documented and analysed by scholars such as Somadeva.
The paintings include human figures, animals, geometric patterns and symbolic motifs, suggesting ritual practices, storytelling and shared cultural memory. “If Tantirimale functioned as a common meeting place for independent territorial groups,” Dr. Rathnayake observes, “then these images may represent a shared visual narrative — a way of communicating identity and belief beyond spoken language.”
One of the caves, previously known to contain both human and animal figures, has deteriorated significantly and now requires urgent conservation intervention. The second cave, however, offers a rare and intriguing glimpse into prehistoric ecological awareness.
Among the animal figures are two images believed to represent a Leatherback Sea Turtle and either a crocodile or land monitor, measuring 18 and 13 centimetres respectively. The turtle depiction is particularly striking for its anatomical accuracy — the ridges on the carapace are clearly visible, aligning closely with known herpetological characteristics.
“These details suggest close observation of nature,” says Dr. Rathnayake. Archaeological evidence supports this interpretation. According to earlier studies, sea turtles were transported to Anuradhapura as early as 800 BC. During the Gedige excavations in 1985, bones of the Olive Ridley sea turtle were discovered, possibly used for ornaments or utilitarian objects. Images of land monitors and crocodiles are common in dry-zone rock art, reflecting both ecological familiarity and subsistence practices, as Veddas are known to have consumed the flesh of land monitors.
Today, Thantirimale stands at a critical crossroads. Encroaching vegetation, weathering stone, fading pigments and increasing human pressure threaten a site that encapsulates millennia of human adaptation, belief and artistic expression. For Dr. Rathnayake and his team, the need for protection is urgent.
“Thantirimale is not just an archaeological site or a temple,” he says. “It is a living record of how humans have interacted with this landscape over thousands of years. Preserving it is not simply about protecting ruins — it is about safeguarding the long memory of this island.”
In the quiet of the rock shelters, where prehistoric hands once painted turtles, hunters and symbols of meaning, Thantirimale continues to whisper its story — a story written not in ink or inscription, but in stone, pigment and belief.
