Few figures in late antiquity present as compelling a historical debate as Julian the Apostate’s attempt to restore the Greek gods in opposition to Christianity in the Roman Empire.

During his brief but highly consequential reign in the fourth century AD, the Roman Empire stood at a profound religious crossroads. For a short period, Julian attempted to slow the empire’s accelerating Christianization, launching a sweeping effort to revive the ancient Olympian pantheon and return Rome to its traditional pagan practices. His sudden death on the battlefield has led historians to debate how dramatically the cultural trajectory of Western civilization might have shifted had his reforms endured.

Julian was born into the heart of the Constantinian dynasty, a family that had only recently converted to Christianity. Nonetheless, he became the last Roman emperor to openly support and worship the traditional Greek gods. He ruled for only about two years from 361 to 363 AD, but he acted with urgency and purpose. Julian the Apostate initiated an extensive program of philosophical and religious reform, aiming to reverse the Christian expansion advanced by his predecessors. To the growing Christian population, he was seen as a traitor to the new religious order, but to those who still admired the intellectual and cultural legacy of the classical world, he appeared as a philosopher-king attempting to restore an older vision of Rome.

Julian the Apostate’s early life

Julian did not experience the typical sheltered upbringing of an imperial heir. He grew up constantly looking over his shoulder, surviving political purges that eliminated many members of his own family. Although he was raised in a strict Christian environment under the supervision of powerful bishops, he is often understood to have developed a private intellectual attraction to classical texts and traditions associated with the ancient world.

His life took a decisive turn when he went to study in Athens. There, he was secretly initiated into the Eleusinian Mysteries, an experience that deeply shaped his philosophical outlook and strengthened his commitment to rejecting Christianity in favor of Neoplatonism. This forced dual existence helped form a uniquely strategic mindset. He became familiar with the inner workings of the Church, knowledge he later leveraged in support of his own religious and philosophical aims. By the time his troops in Gaul unexpectedly proclaimed him emperor, Julian was convinced that the gods themselves had chosen him to restore the ancient order.

Julian the Apostate as Emperor and the worship of the Ancient Greek gods in the Roman Empire

When he finally took power, Julian did not launch the kind of widespread, violent persecutions often associated with earlier periods of religious conflict. Instead, he pursued a more calculated cultural strategy. His approach focused on weakening Christian influence within imperial institutions while strengthening traditional religious structures. Julian the Apostate reduced the privileges and state support enjoyed by Christian clergy and redirected resources and prestige toward the priesthood of the traditional Greco-Roman religion centered on the Greek gods.

In a particularly controversial move, he restricted Christians from teaching classical literature. His reasoning was that those who rejected the traditional religious framework of Homer and Hesiod should not profit from instructing it. At the same time, Julian sought to make traditional religion more socially competitive by encouraging pagan priests to adopt public charitable functions, including aid for the poor and the establishment of hospitals—areas in which Christianity had been especially successful in gaining support. He appears to have believed that traditional worship had declined not because of its inherent weakness but because its institutions had failed to match the organizational and charitable presence of Christianity.

In practice, many historians argue that this cultural and intellectual strategy posed a different kind of challenge to early Christianity than outright violence. While persecution could strengthen Christian identity through martyr narratives, Julian the Apostate’s policies instead aimed to limit the social structures that supported its continued expansion while restoring the worship of the Ancient Greek gods within the broader Greco-Roman religious tradition.

Unfortunately for his beliefs, that grand vision of such a revived Greco-Roman empire came to an abrupt end in the arid regions of Persia. During a military campaign, Julian was struck in the side by a spear, cutting his reign tragically short. Ancient sources and later traditions continue to debate the circumstances of his death, with some attributing the blow to a Persian soldier and others speculating—without evidence—that it may have come from within his own ranks. The true origin remains uncertain.

A well-known tradition holds that, as he lay dying, Julian the Apostate is said to have declared, “Thou hast conquered, O Galilean,” acknowledging the perceived triumph of Christianity. Whether or not he actually spoke these words, his brief reign left a lasting imprint on Roman and Western history. His efforts to restore the Ancient Greek gods within the Roman world continue to be discussed by historians as a striking moment in the empire’s religious transformation. Even in modern Greek cultural memory, echoes of this tension can still be felt in the broader contrast between the rational legacy of ancient philosophy and the spiritual tradition of Orthodox Christianity.

Every day, thousands of Athenians and visitors pass through Michalakopoulou Avenue, one of the main arteries of central Athens. Yet few know the story of Andreas Michalakopoulos, the forgotten Greek Prime Minister and diplomatic genius whose name the avenue carries.

Who was the man behind the Michalakopoulos name?

Andreas Michalakopoulos was born in Patras in 1876 and went on to become one of the most important statesmen in modern Greek history. He was a man who helped redraw Greece’s borders, solved Athens’ water crisis, and brokered peace with Turkey at a time when Greece couldn’t have suffered more militarily.

Yet most Greeks today could not tell you a single thing about him. History has been unkind to Michalakopoulos, largely because he spent most of his career standing next to one of the most towering figures Greece has ever produced: Eleftherios Venizelos. That proximity was both his greatest role and the reason he is so rarely remembered—a blessing and a curse for a public figure like him. Michalakopoulos rose through the Liberal Party (Κόμμα των Φιλελευθέρων) ranks after 1910, holding portfolios in Economy, Agriculture, and Military Affairs under successive Venizelos governments.

He was not a man who craved the spotlight. He was a man who understood how government actually worked, and he was trusted with the levers of it accordingly—a true politician in the best definition of the term possible. When Venizelos went before the great powers of Europe to argue for a bigger Greece after the First World War, Michalakopoulos was beside him at the negotiating table. He participated in the long, tough diplomacy that produced both the Treaty of Sèvres in 1920 and the Treaty of Lausanne in 1923, the two documents that first promised the unthinkable and then permanently fixed, without too heavy losses, the borders of the modern Greek state. Venizelos got 100% of the credit.

However, Michalakopoulos did much of the work. He became Prime Minister in October 1924, inheriting a country in a genuine, profound, and almost existential crisis. The Asia Minor Catastrophe of 1922 had sent over a million Greek refugees flooding into Greece in a matter of months. From dreams about the reinstatement of Byzantine glory, Greece woke up in ruins, literal and metaphorical. Athens had nearly doubled in population within just a few years, and the city’s ancient water infrastructure simply could not cope. Water was being sold from carts in the streets. Taps ran dry. For a capital city that had stood for thousands of years, it was an embarrassing and dangerous situation. Greece was on the brink of collapse.

Michalakopoulos wasted little time. In December 1924, his government signed a landmark contract with American engineering firm Ulen & Company and the Bank of Athens to construct the Marathon Dam. It was one of the largest infrastructure projects in Europe at the time. The Marathon Dam was a gravity dam built of the famous Pentelic marble—the same stone used to construct the Parthenon—rising 54 meters above the Haradros River outside of Athens. The project cost more than the entire National Bank of Greece and was funded with a $10 million loan. Yes, modern Greece and loans, this stereotypical love affair…

Construction ran from 1926 to 1929. The finished system delivered water to Athens through nearly 880 kilometers (547 miles) of new pipes and was inaugurated in 1931. The water that flows from Athenian taps today finds its roots in that contract and in that decision. Michalakopoulos never saw it completed. A military coup by General Theodoros Pangalos ended his government in June 1925, just months after the contract was signed.

But, thankfully, the work was done. He returned to government as Foreign Minister under Venizelos starting in 1928, and it was here that he made perhaps his most lasting contribution to the nation. Greece in the late 1920s was a country that had been through a lot. The Megali Idea, the great dream of a Greece stretching across the Aegean and into Anatolia, had collapsed spectacularly and catastrophically. The population exchange with Turkey had displaced more than a million people on each side. The two countries were locked in mutual suspicion and unresolved property disputes.

Michalakopoulos understood, more clearly than most, that Greece could not afford to stay that way. On October 30, 1930, he co-signed the Greek-Turkish Friendship Convention, also known as the Treaty of Ankara. He did that alongside Venizelos and Turkish Prime Minister İsmet İnönü. The treaty settled the border, resolved the property claims of the displaced populations, and established naval parity in the eastern Mediterranean.

It was a remarkable diplomatic achievement that helped lay the groundwork for the Balkan Pact of 1934 and brought a genuine, working peace between two nations that had spent generations at war. When Ioannis Metaxas declared his dictatorship on August 4, 1936, Michalakopoulos refused to go along with it. He had spent thirty years building democratic institutions from the inside. He spoke out against the regime and paid a heavy price for it. He was sent into internal exile on the island of Paros. He died on March 7, 1938, aged sixty-one.

Michalakopoulos’ legacy is a strange one: a man who brought water to a thirsty city, helped draw the map of modern Greece, made peace with its archenemy, and died in exile because he would not pretend that democracy was something you could simply switch off. Next time the traffic backs up on Odos Michalakopoulou in downtown Athens, take a moment to read the sign. The water in your glass and the borders of this nation have everything to do with the man it honors.

Throughout history, and since the first exchanges between India and ancient Greece, Greeks have been captivated by the intriguing stories of the mysterious gymnosophists of India or the “naked philosophers.”

These philosophers became infamous for their austere and ascetic lifestyle along with their enigmatic wisdom. There are numerous Greek accounts of these wise people, offering a fascinating picture of the important cultural exchanges between two of the greatest civilizations on Earth.

Encounters with Alexander the Great

One could argue that perhaps the most famous interactions between Greeks and the gymnosophists took place during the campaign of Alexander the Great in India in 326 BC.
Ancient historians such as Onesicritus and Nearchus described (in their works) the dialogues that the great Macedonian Greek commander had with these naked wise men.

During these dialogues, we can see their distinctive disregard for any material possessions and their truly spectacular willingness to embrace death as a part of life. The philosopher Calanus famously demonstrated this by actually setting himself on fire in front of Alexander in an extreme attempt to showcase his fearless nature.

These examples are only a part of the entire collection of accounts that have managed to paint a vivid picture of the unconventional way of life of the gymnosophists. Porphyry, for instance, noted in his works that these Indian philosophers were strictly vegetarians, much like the Brahmins. Their absolute rejection of garments and clothing, in general, along with their distaste for worldly goods in pursuit of spiritual enlightenment made a deep impression on the Greeks, who were genuinely amazed by the dedication of these men.

Ancient Greece’s views on philosophy of India

For the Greeks and their worldview, the gymnosophists represented a very different and acutely unique philosophical tradition with both many similarities to but also divergences from their own. From the accounts of ancient writers we learn that Greeks saw similarities between the ideas from gymnosophists of India and their own Greek philosophical concepts.

The belief of the gymnosophists for example in reincarnation, or metempsychosis, was of particular interest to many. Some scholars even speculated that Greek thinkers such as Pythagoras may have been influenced by Indian thought in the way he shaped his own worldview.

However, it is obvious that the Greeks also noted differences. This is something that probably led to a greater curiosity about and fascination with the Indian gymnosophists. Unlike the gymnosophists, mainstream Greek philosophers tended to engage more with society and politics, becoming much more active in the everyday life of their cities. The radical asceticism of the gymnosophists, on the other hand, as well as their rejection of material life, was more extreme than most Greeks had ever witnessed.

Asceticism and self-denial—from India’s gymnosophists to ancient Greece

What seems to have impressed the Greeks the most about the gymnosophists and their life was their incredible commitment to self-denial and extreme austerity. These naked wise men renounced almost all possessions and lived in the wilderness away from urban centers of the time.

Their sole goal was to pursue spiritual wisdom through material deprivation. To Greek eyes, their extremely ascetic lifestyle represented the ultimate mastery over physical desires and earthly attachments. For the Greeks, this was almost inherently difficult to comprehend, as the Greeks had a fundamentally different view, which was much closer to today’s Western attitude towards material possessions.

This is the reason why the example of living adopted by the gymnosophists inspired some Greek philosophical movements, particularly the Cynics. The Cynics were the ones who emulated the Indian rejection of social norms and material goods in favor of the benefits of asceticism. Christian ascetics also later looked to the Indian philosophers as true role models of self-discipline and pure piety.

India’s gymnosophists and influences on ancient Greece

As is understandable, the gymnosophists played a fundamental role in shaping and affecting the Greek imagination. They appeared as archetypal wise men in works by authors like Plutarch, Lucian, and Clement of Alexandria. Their fascinating way of life continued to amaze later Greek and Roman writers. These writers saw them as exotic embodiments of the philosophical ideal.

More broadly speaking, the Greek encounters with the gymnosophists show us the importance and richness of the cultural exchanges and the discourse of ideas between ancient cultures and civilizations. These Indian wise men expanded many of the Greek notions of philosophy and the possibilities of the ascetic path, even shaping Christian thought, although they lived centuries before the birth of Jesus. At the same time, the Greek accounts give us valuable information about the fundamentals of Indian thought and practice.

Most of us assume that looking after our teeth is a modern habit shaped by supermarket shelves, mint-flavored ads, and childhood dentist scares, but a surviving Ancient Greek toothpaste recipe suggests otherwise.

Sitting quietly in the Austrian National Library in Vienna is one of the most remarkable documents in the history of medicine: a small, faded papyrus from the fourth century AD containing what is widely considered the world’s oldest surviving, precise toothpaste formula.

The existence of this Ancient Greek toothpaste recipe points to something larger at work. By the time it was copied onto papyrus, Greek had long since become the language of science, medicine, and intellectual life across the Mediterranean. This linguistic dominance was a legacy of the conquests of Alexander the Great and, above all, of Alexandria, the city his successors transformed into the ancient world’s foremost hub of knowledge. Even in Roman Egypt, centuries after the Ptolemies had given way to the Caesars, Greek remained the language a physician used when he wanted to be taken seriously.

When was the toothpaste recipe written in Ancient Greek discovered?

The papyrus first came to the attention of modern researchers in 2003, when curators at the Austrian National Library in Vienna identified it while preparing for an international dental congress. It had likely been sitting in the collection for years, its significance unnoticed and largely forgotten. Once translated, however, scholars quickly realized what they were looking at—a toothpaste formula that predates the first commercially marketed toothpaste, Colgate, launched in 1873, by well over fifteen hundred years.

The formula itself is strikingly systematic. The scribe prescribes “a powder for white and perfect teeth” composed of four ingredients: one drachma of rock salt, two drachmas of mint, one drachma of dried iris flower, and twenty grains of pepper. The drachma in this context was a standard unit of Greek medical weight, roughly equivalent to one-eighth of an ounce (about 3–4 grams), part of the same measurement system used throughout the major pharmacological texts of the ancient world. Taken together, the recipe reads less like folklore and more like a physician’s deliberate prescription, carefully calibrated for a patient.

But one might wonder if it actually worked. In 2003, Austrian dentist Dr. Heinz Neuman decided to test it for himself by recreating the formula. His conclusion was cautious but intriguing: the mixture was mildly abrasive and caused slight gum bleeding, yet it also produced a noticeable sensation of cleanliness and freshness. Modern dental science helps explain why. Dried iris flower, or orris root, is now known to contain antibacterial compounds that target the pathogens responsible for gum disease. What might once have looked like ancient guesswork increasingly appears to be empirical knowledge derived through observation and practice. In this sense, modern pharmaceutical science is only now arriving at conclusions the Greeks and Egyptians had already explored more than a thousand years earlier.

None of this should entirely surprise us when we consider the world from which this recipe emerged. Ancient Greece had produced Pedanius Dioscorides, whose monumental work on medicinal plants shaped medical practice for more than a millennium. It had also produced physicians, botanists, and scholars who approached the human body with a level of rigor and curiosity that few ancient traditions matched. The anonymous scribe who recorded this formula was working squarely within that intellectual lineage, effectively encoding practical medical knowledge in Greek because it was the language in which serious medicine was conducted at the time.

The paste itself would have been applied without anything resembling a modern toothbrush. A folded linen cloth or a frayed chew stick—a fibrous twig worn soft at the tip through repeated use—would have served the purpose well enough. The tools were simple, but the intention was essentially the same as ours.

There is a quiet continuity in that detail. The next time you reach for mint toothpaste in the morning, you are participating in a ritual that a Greek-speaking scribe in Roman Egypt thought important enough to preserve on papyrus seventeen centuries ago. The ingredients have been refined, the packaging has changed beyond recognition, and no one is applying the mixture with linen anymore. Still, the impulse behind it—the very human desire for clean, white teeth—remains as old as the ancient world itself, and in many ways, the Ancient Greek world had already put the first working version of the answer into writing.
