When Reptiles Ruled the Rupee

Published

Senior banker Dr. Nimal Rathnayake tells The Sunday Island how Sri Lanka’s currency evolved from ancient Kahapanas to colourful banknotes that celebrated the island’s hidden biodiversity.

“Money tells stories — not just of kings and commerce, but of art, identity, and nature,” said Dr. Nimal Rathnayake, senior banker, researcher, and member of the IUCN Species Survival Commission, speaking to The Sunday Island.

His lifelong curiosity about the intersection of economy and ecology has led him to a fascinating observation: reptiles, those silent survivors of Sri Lanka’s wilderness, have left their mark even on the nation’s banknotes.

For Dr. Rathnayake, currency is far more than a medium of exchange. “It’s a mirror of our civilisation,” he explained. “Every coin and note reflects the political, cultural, and ecological pulse of the era it was born in.”

From Barter to the Birth of Coinage

Long before bank vaults and interest rates, trade on the island flowed through barter and simple tokens. Farmers swapped rice for honey, craftsmen traded tools for spices. Around the 3rd century B.C., Sri Lanka’s earliest coins — the Kahapanas — entered circulation.

“These punch-marked silver coins,” Dr. Rathnayake told The Sunday Island, “were etched with symbols like the swastika, fish, and sun. Each mark carried meaning — prosperity, power, or protection. They were as much talismans as they were tender.”

Over centuries, these symbols evolved with dynasties. The Maneless Lion coins, Lakshmi plaques, and Kahavanu reflected Anuradhapura’s and Polonnaruwa’s artistry. Traders arriving from Rome, Arabia, and China introduced their own currencies — proof that Sri Lanka’s harbours pulsed with international exchange long before the modern era.

“Coins tell the story of connectivity,” Dr. Rathnayake noted. “You can trace our links with the world through what we minted and what we accepted.”

Colonial Mints and Monetary Modernity

When European powers arrived — Portuguese, Dutch, and then the British — Sri Lanka’s coins began to carry foreign emblems alongside local motifs. From the Rix Dollar and Stuiver to the Pagodi and Tanga, money became a reflection of shifting empires.

The establishment of the Central Bank of Ceylon in 1950 marked a turning point. The new nation, freshly independent, sought monetary sovereignty.

“The Central Bank didn’t just regulate finance,” Dr. Rathnayake explained. “It became a curator of identity — deciding which faces, flora, and fauna would tell the story of a nation on its notes.”

The Bank’s mission, enshrined under the Monetary Law Act No. 58 of 1949, was to ensure financial stability while supporting economic growth. Yet behind those technical mandates, another mission quietly unfolded: to design notes that celebrated Sri Lanka’s rich cultural and natural heritage.

The Arrival of the Banknote

Though coins dominated for centuries, paper currency made its Sri Lankan debut under Dutch rule. On May 10, 1785, the first batch of banknotes — printed in denominations from 1 to 1000 Pathaga — entered circulation. Their purpose was practical: to fund security and administration. But they also represented the first step toward modern banking.

“Each note was hand-signed by three officials,” said Dr. Rathnayake. “They weren’t just receipts — they were promises, backed by trust.”

Later, during the British era, new denominations emerged alongside coins. Notes printed in Colombo and London bore the royal insignia, colonial crests, and maritime emblems — blending imperial authority with local pride. By the mid-20th century, these designs began to evolve into distinctly Sri Lankan creations.

The Laki Senanayake Revolution

In 1979, a new chapter unfolded. The Central Bank released the Flora and Fauna Series, designed by the late Laki Senanayake, the iconic artist, sculptor, and environmental visionary.

“This was a masterpiece of national storytelling,” said Dr. Rathnayake, speaking to The Sunday Island with admiration. “Laki took our biodiversity — trees, birds, fish, reptiles — and placed them in everyone’s hands.”

Each note burst with colour and ecological symbolism. The design captured more than beauty; it celebrated endemism. “It was as if the island’s forests, rivers, and dry plains had come alive in ink,” he added.

Senanayake, who spent years observing nature from his home at Diyabubula, understood that art and conservation could coexist. His designs echoed his belief that human progress and natural heritage must grow together — a message as urgent now as it was then.

The Reptiles Beneath the Ink

Among the six notes in the 1979 series, two bore creatures that rarely make headlines: the Haly’s Tree Skink (Dasia haliana) and the Damon Ground Gecko (Cyrtodactylus yakhuna) — both endemic, both distinctly Sri Lankan.

On the two-rupee note, Dasia haliana appears alongside the curry leaf tree (Murraya koenigii), black ruby barb, and lacewing butterfly — a snapshot of the dry zone’s living tapestry. The skink, slender and slow-moving, prefers large trees and feeds on insects. Its dark crossbands stand out vividly on the young lizard’s body, a striking pattern that once caught Senanayake’s artistic eye.

“The presence of this humble tree skink on our currency,” Dr. Rathnayake observed, “is deeply symbolic. It reminds us that even the smallest lives in our forests are part of our national wealth.”

The five-rupee note featured Cyrtodactylus yakhuna, or the Damon Ground Gecko — a nocturnal reptile that inhabits the leaf litter of Polonnaruwa and Anuradhapura. With its cream-brown body and irregular bands, the gecko may not command attention, but in the quiet rhythm of the dry zone night, it reigns.

“These species are not majestic like elephants or flamboyant like peacocks,” he told The Sunday Island. “Yet they embody resilience — surviving in balance with the environment. Laki captured that truth beautifully.”

Sri Lanka’s Reptilian Riches

Sri Lanka today is home to 246 species of reptiles — from the elusive chameleons and skinks to the formidable crocodiles and monitor lizards. Out of these, 165 are endemic, and 122 are threatened, placing the island among the world’s top tropical regions for reptilian diversity.

“The numbers tell a powerful story,” Dr. Rathnayake said. “They speak of both abundance and vulnerability.”

He stressed that conservation is no longer an optional pursuit. “When a child sees a gecko or skink on a banknote and asks, ‘What is this creature?’, that question itself is a spark — it’s how awareness begins.”

Currency as a Cultural Canvas

Dr. Rathnayake believes that the role of currency extends beyond economics. “Notes are cultural ambassadors,” he asserted. “They travel, they’re exchanged, they circulate — carrying with them the story of who we are.”

Indeed, Sri Lanka’s evolution through twelve series of banknotes — from King George VI’s portrait to the 2010 ‘Development, Prosperity and Sri Lankan Dancers’ series — maps a nation’s journey from colonial dependency to confident sovereignty.

“In 1951, our notes carried foreign monarchs,” he recalled. “Today, they carry our dancers, heritage sites, and wildlife. That’s progress in print.”

Even as the world moves toward cashless transactions, he argues that printed money still holds a profound emotional and educational value. “A digital wallet cannot capture the brushstrokes of a Laki Senanayake,” he said with a smile. “You can’t smell the ink, or feel the texture of heritage.”

Echoes of the Past, Lessons for the Future

As Dr. Rathnayake leafed through his collection of old coins and faded notes, there was reverence in his gaze. Each artifact, he said, carries not just economic history but ecological wisdom.

“Our ancestors didn’t separate nature from value,” he reflected. “They understood that the land, its rivers, and its creatures were sources of wealth. In many ways, our coins and notes are quiet reminders of that balance.”

He paused before adding, “When we destroy ecosystems, we’re erasing not just species — we’re erasing stories. The Haly’s Tree Skink and Damon Ground Gecko may be small, but they’ve earned a place in our national narrative. That’s something to celebrate.”

An Enduring Symbol

In an era when plastic money and virtual payments dominate, few pause to look at the quiet artistry in their wallet. But perhaps they should. The next time you hand over a note, think of the brush that drew it, the forest it represents, and the reptile it immortalised.

“Money,” said Dr. Rathnayake, speaking to The Sunday Island, “may change form, but its power to tell stories endures. And on our island, those stories often begin with nature.”

He smiled, tucking a weathered five-rupee note back into his folder. “It’s not just currency,” he said softly. “It’s memory — of who we are, and the living world that shaped us.”

Fractious West facing a more solidified Eastern opposition

Published

on

Going forward, it is hoped that a reported ceasefire agreement between the US and Iran would provide a basis for a degree of stability in the Middle East and pave the way for substantive peace talks between the powers concerned. The world is compelled to fall back on hope because there is never knowing when President Donald Trump would change his mind and plans on matters of the first importance. So erratic has he been.

Yet, confusion abounds on who has agreed to what. The US President is on record that a number of conditions put forward by him to Iran to deescalate tensions have been accepted by the latter, whereas Iran is yet to state unambiguously that this is so. For instance, the US side claims that Iran has come clear on the point that it would not work towards acquiring a nuclear weapons capability, but there is no official confirmation by Iran that this is so. The same goes for the rest of the conditions.

Accordingly, the peace process between the US and Iran, if such a thing solidly exists, could be said to be mired in uncertainty. Nevertheless, the wider publics of the world are bound to welcome the prospects of some sort of ceasing of hostilities because it would have the effect of improving their economic and material well being which is today under a cloud.

However, questions of the first magnitude would continue to bedevil international politics and provide the breeding ground for continued tensions between East and West. Iran-US hostilities helped highlight some of these divisive issues and a deescalation of these tensions would not inevitably translate into even a temporary resolution of these questions. The world community would have no choice but to take them up and work towards comprehending them better and managing them more effectively.

For example, there are thorny questions arising from the Treaty on the Non-Proliferation of Nuclear Weapons (NPT). Essentially, this treaty bans the processing and use of nuclear weapons by states but some of the foremost powers are not signatories to it.

Moreover, the NPT does not provide for the destroying of nuclear arsenals by those signatory states which are already in possession of these WMDs. Consequently, there would be a glaring power imbalance between the latter nuclear-armed states and others which possess only conventional weapons.

Such a situation has grave implications for Iran’s security, for instance. The latter could argue, in view of the NPT restrictions, that the US poses a security threat to it but that it is debarred by the Treaty from developing a nuclear arms capability of its own to enable it to match the nuclear capability of the US. Moreover, its regional rival Israel is believed to possess a nuclear weapons capability.

Accordingly, a case could be made that the NPT is inherently unfair. The US would need to help resolve this vexatious matter going forward. But if it remains, US-Iran tensions would not prove easy to resolve. The same goes for Iran-Israeli tensions. Consequently, the Middle East would remain the proverbial ‘powder keg’.

Besides the above issues, the world has ample evidence that it could no longer speak in terms of a united NATO or West. Apparently, there could be no guarantee that US-NATO relations would remain untroubled in future, even if the current Iran-US standoff is peacefully resolved. US-NATO ties almost reached breaking point in the current crisis when the US President called on its NATO partners, particularly Britain, to help keep open the Hormuz Straits for easy navigation by commercial vessels, militarily, on seeing that such help was not forthcoming. Such questions are bound to remain sore points in intra-Western ties.

In other words, it would be imperative for the US’ NATO partners to help pull the US’ ‘chestnuts out of the fire’ going ahead. The question is, would NATO be willing to thus toe the US line even at the cost of its best interests.

For the West, these fractious issues are coming to the fore at a most unpropitious moment. The reality that could faze the West at present is the strong opposition shown to its efforts to bolster its power and influence by China and Russia. Right through the present crisis, the latter have stood by Iran, materially and morally. For instance, the most recent Security Council resolution spearheaded by the US which was strongly critical of Iran, was vetoed by China and Russia.

Accordingly, we have in the latter developments some marked polarities in international politics that could stand in the way of the West advancing its interests unchallenged. They point to progressively intensifying East-West tensions in international relations in the absence of consensuality.

It is only to be expected that given the substance of international politics that the West would be opposed by the East, read China and Russia, in any of the former’s efforts to advance its self interests unilaterally in ways that could be seen as illegitimate, but what is sorely needed at present is consensuality among the foremost powers if the world is to be ‘a less dangerous place to live in.’ Minus a focus on the latter, it would be a ‘no-win’ situation for all concerned.

It would be central to world stability for International Law to be upheld by all states and international actors. Military intervention by major powers in the internal affairs of other countries remains a principal cause of international mayhem. Both East and West are obliged to abide scrupulously with this principle.

From the latter viewpoint, not only did the West err in recent times, but the East did so as well. Iran, for instance, acted in gross violation of International Law when it attacked neighbouring Gulf states which are seen as US allies. Neither Iran nor the US-Israel combine have helped in advancing international law and order by thus taking the law into their own hands.

Unfortunately, the UN has been a passive spectator to these disruptive developments. It needs to play a more robust role in promoting world peace and in furthering consensual understanding among the principal powers in particular. The need is also urgent to advance UN reform and render the UN a vital instrument in furthering world peace. The East and West need to think alike and quickly on this urgent undertaking.

Science-driven health policies key to tackling emerging challenges — UNFPA

Published

on

Dr. Dayanath Ranatunga

Marking World Health Day on April 7, health experts have called for a stronger commitment to science-based decision-making to address increasingly complex and evolving health challenges in Sri Lanka and beyond.

Dr. Dayanath Ranatunga, Assistant Representative of the United Nations Population Fund, stressed that health is no longer confined to hospitals or traditional medical systems, but is shaped by a broad spectrum of social, environmental, and technological factors.

“This year’s theme, ‘Together for Health. Stand with Science,’ reminds us that science is not only for laboratories or policymakers. It is a way of thinking and a tool that shapes everyday decisions,” he said.

Dr. Ranatunga noted that modern health challenges are increasingly interconnected, ranging from infectious diseases such as COVID-19 to climate-related risks, demographic shifts, and emerging forms of online violence.

He warned that maternal and newborn health continues to demand urgent attention despite progress. Globally, an estimated 260,000 women died from pregnancy and childbirth-related causes in 2023 alone—many of them preventable through timely, science-based interventions.

“In countries like Sri Lanka, where fertility rates are declining and survival rates improving, every pregnancy carries greater significance—not just for families, but for the future of communities and economies,” he said.

The UNFPA official also highlighted the growing threat of Technology Facilitated Gender-Based Violence (TFGBV), including cyber harassment and online abuse, noting that these forms of violence can have deep psychological consequences despite lacking visible physical harm.

He emphasised the need for multidisciplinary, science-informed approaches that integrate mental health, digital safety, and survivor-centered care.

Turning to demographic trends, Dr. Ranatunga pointed out that increasing life expectancy is bringing new challenges, particularly the rise of non-communicable diseases such as diabetes, cardiovascular illnesses, and cancers.

In Sri Lanka, nearly 13.9% of mothers develop diabetes during pregnancy, a trend attributed to obesity and unhealthy lifestyles, underscoring the urgent need for preventive healthcare strategies.

“Are we investing enough in prevention?” he asked, noting that early intervention and healthier lifestyles could significantly reduce long-term healthcare costs, especially in a country with a free public healthcare system.

He underscored the importance of data-driven policymaking, stating that scientific research and analytics enable governments to identify gaps, anticipate future needs, and allocate resources more effectively.

The UNFPA, he said, is already leveraging tools such as Geographic Information Systems (GIS) to improve access to maternal healthcare, including mapping travel times for pregnant women to reach health facilities.

Digital innovation is also transforming healthcare delivery, from telemedicine to real-time data systems, improving efficiency and ensuring continuity of care even during emergencies.

In Sri Lanka, partnerships between the government and development agencies are helping to modernise training institutions, including facilities in Batticaloa, equipping healthcare workers with both clinical and digital skills.

However, Dr. Ranatunga cautioned that technology alone is not a solution.

“It must be guided by evidence and grounded in equity,” he said, pointing out that women’s health remains significantly underfunded, with only about 7% of global healthcare research focusing on conditions specific to women.

He also drew attention to the growing health impacts of climate change, including extreme weather, food insecurity, and displacement, describing it as an emerging public health crisis.

“Health does not begin in hospitals. It is shaped by the environments we live in, the choices we make, and the systems we build,” he said.

Calling for renewed commitment, Dr. Ranatunga urged stakeholders to invest in prevention, embrace innovation, and ensure that science remains central to policy and practice.

“Science is not just about knowledge—it is about ensuring that everyone has the opportunity to live healthy, dignified lives, and that no one is left behind,” he added.
