Megasthenes and the Indica: A Greek Envoy in Mauryan India

Megasthenes was a Greek diplomat sent around 302 BC by Seleucus I to the court of Chandragupta Maurya at Pataliputra, capital of the Maurya Empire. His book, the Indica, gave the most detailed description of India available to the Greek and Roman world. Although the original is lost, quotations by later writers preserve his account of Pataliputra, Mauryan government and Indian society, making him a key witness to India around 300 BC.

The envoy

Megasthenes was probably born around 350 BC, perhaps in Ionia in western Anatolia. The historian Arrian says he lived at the court of Sibyrtius, the Macedonian satrap of Arachosia, around modern Kandahar, and that he often visited the Indian king Sandrocottus, the Greek name for Chandragupta.

His mission followed the Seleucid-Mauryan War, which ended around 303 BC with a treaty and a marriage alliance. Seleucus sent Megasthenes to Chandragupta Maurya, probably around 302 BC. Whether he made one long stay or several visits, and exactly when, is debated; dates between about 302 and 288 BC have been proposed.

The Indica

Megasthenes wrote his Indica in four books, covering the geography, peoples, customs, history and government of India. The work has not survived. Most of what we know comes from Diodorus Siculus in the 1st century BC, Strabo in the early 1st century AD, Arrian in the 2nd century AD, and Pliny the Elder.

In 1846 the German scholar E. A. Schwanbeck collected these fragments, and in 1877 J. W. McCrindle published an English translation. Because each later writer chose and reworded what he quoted, it is often hard to know Megasthenes’ exact words.

Pataliputra and the Mauryan state

Megasthenes’ most famous passage describes Pataliputra, which he called Palibothra. He said it was 80 stadia long and 15 wide, about 14.5 by 2.7 km, enclosed by a timber wall with 570 towers and 64 gates and a ditch for defence and drainage. Wooden palisades found by archaeologists at Patna support his description.

He described a powerful, organised state. Officials looked after roads, rivers and irrigation, measured land and collected taxes. The city was run by six boards of five members each, and the army by six more boards, including one for elephants and one for transport and supplies. The king lived amid heavy security and was guarded by armed women.

Land, army and nature

Megasthenes was struck by the fertility of India. He described two harvests a year, thanks to summer and winter rains, and great rivers such as the Ganges, which he thought the largest in the world. According to Diodorus, he reported that farmers paid a share of their produce to the king, and that soldiers did not harm farmers working in the fields even while battles were fought nearby.

He also wrote about the army. Horses and elephants, he said, belonged to the king alone, and soldiers were paid from the royal treasury and supplied with weapons in peacetime as well as war. His accounts of how wild elephants were captured and trained, preserved by Arrian and Strabo, are among the most detailed in ancient literature.

Indian society

Megasthenes divided Indian society into seven classes: philosophers, farmers, herders and hunters, artisans and traders, soldiers, overseers or inspectors, and councillors of the king. He said marriage and change of occupation between classes were not allowed. His scheme does not match the four varnas of Indian texts, and historians think it combines real observation with Greek ways of classifying people.

He distinguished two kinds of philosophers, the Brachmanes and the Sarmanes, corresponding to Brahmins and Shramanas, the wandering ascetics who included Buddhists and Jains. He also said the people of Mathura worshipped a god he identified with Heracles, which many scholars take to be an early reference to Krishna.

Some of his claims are clearly wrong. He stated that there was no slavery in India, though Indian sources show that slavery existed, and that India never suffered famine. He also repeated fabulous stories, such as gold-digging ants and peoples without mouths. Strabo called him unreliable for such tales.

Legacy

For centuries, Megasthenes’ work shaped how Greeks and Romans imagined India, and later writers such as Arrian relied on him. Modern historians use him cautiously, alongside Indian texts like the Arthashastra and the edicts of Ashoka, but he remains one of the few contemporary outside observers of the early Maurya Empire, much as Herodotus is for Persia.

Why it matters

Megasthenes provides a rare outsider’s view of India around 300 BC, from the size of its capital to the workings of its government. Although his work survives only in fragments and contains errors, it is a cornerstone of the history of the Maurya Empire and of early contact between Greece and India.
