Religion, Royal Representation and Cultural Exchange in the Indo-Greek World

The Indo-Greek kingdoms were a changing group of monarchies in the northwestern Indian subcontinent, with territories that included parts of present-day Afghanistan, Pakistan and northwestern India. From the second century BCE into the early first century CE, their rulers used coin images and inscriptions to represent royal authority in regions where Greek and local traditions met. The evidence points to varied religious connections, not a single, uniform state religion.

A coin could place a king’s name beside a divine image, while a dedication named a particular person making a gift. The religious connections in these records involved both courtly representation and individual participation. Later Buddhist writing added another form of remembrance by making Menander a questioner in an extended dialogue about the teaching.

A plural religious landscape across changing kingdoms

Indo-Greek rulers used images of Zeus, Athena, Heracles and Apollo on their money. These figures carried recognisable attributes: Athena could appear with weapons, Heracles with a club, and Zeus with a thunderbolt. Repetition made a design identifiable as a royal issue while linking the ruler’s public image with a chosen divine figure.

An image and its inscription worked together. A name established whose issue it was, a title stated a royal claim and a divine figure supplied a visual association. Different kings could alter one element while retaining the familiar format, creating continuity in money even as authority changed.

Coinage and the language of kingship

Coins were a recurring way for rulers to display their portraits, names, titles and divine associations. Indo-Greek issues could pair Greek legends with local-language inscriptions in Indian scripts. Kharosthi, used widely in the northwestern region, appeared on many bilingual coins; some early issues also used Brahmi. Different languages and scripts on a single coin displayed royal authority across a culturally varied realm.

Around 180 BCE, coins of Agathocles presented figures generally identified as Vasudeva-Krishna and Sankarshana-Balarama. Their attributes included a wheel and conch for Vasudeva-Krishna, and a plough and club for Sankarshana-Balarama. The coins also used an Indian-standard square form. Such issues show Greek rulers working with Indian religious imagery and monetary conventions, but this display of Indian deities did not become a regular pattern on later Indo-Greek coins.

One issue of Menander I shows an eight-spoked wheel on one face and a palm on the other. The wheel is often interpreted in relation to Buddhism, where it symbolises the teaching, while the palm belongs to a wider vocabulary of victory. Together they could join religious association with royal success. The type is a particular choice within Menander’s varied coinage.

Some later kings paired the Greek title Dikaios, meaning just, with Dharmikasa in the local-language legend. The latter refers to alignment with Dharma, a term used for religious teaching and moral order in several Indian traditions. Translating royal virtue into this vocabulary made the claim meaningful in another setting without requiring the two words to have precisely identical associations.

Buddhist symbols, dedications and networks

Archaeological evidence at the Butkara stupa, a relic monument in Swat, connects Buddhist building activity with Indo-Greek rule. A coin of Menander was found in the site’s second-oldest construction layer, and Hellenistic architectural decoration was added during the second century BCE. This supports an Indo-Greek-period phase of expansion; it does not establish that Menander personally commissioned the work.

A miniature stone stupa from Swat bears a dedication by Theodotos. He is called a meridarch, a district or provincial official. The inscription says he established relics of the Buddha for the benefit of many people. The text is usually placed before the middle of the first century BCE, but it names no reigning king.

The object’s form gave the dedication a physical purpose. A reliquary held remains venerated as connected with the Buddha, and the miniature stupa reproduced the kind of monument in which relics were enshrined. Naming the donor and the intended benefit made the gift a recorded act of support for a Buddhist sacred setting.

Vāsudeva and Mithra in cross-cultural settings

Around 110 BCE, Heliodorus, an envoy of the Indo-Greek king Antialcidas, dedicated a pillar at Vidisha to Vāsudeva, a deity associated with Krishna. The inscription identifies him as a devotee and as a man from Taxila. His diplomatic journey to the court of King Bhagabhadra thus also left a personal religious monument. The pillar was conceived as a Garuda standard, linking it with the deity’s bird emblem.

Coinage from western Indo-Greek rulers also reflects connections with Iranian religious imagery. A radiant, cap-wearing divine figure on some issues is commonly identified as Mithra or Zeus-Mithra, though precise interpretations can vary. The western kingdoms lay close to Central Asian and Iranian cultural regions, and their coins show that religious representation could differ across the Indo-Greek world.

Menander in Buddhist dialogue and later memory

The Milindapañha, or Questions of Milinda, presents Menander under the name Milinda in dialogue with the Buddhist teacher Nāgasena. The work developed after the king’s lifetime and uses the encounter to explain religious ideas. Its conversion story belongs to the text’s account of an enquiring ruler persuaded by the teaching, rather than to a contemporary royal chronicle.

In one exchange, Nāgasena asks what makes a chariot a chariot: its axle, wheels, frame or something separate from them. Milinda recognises the name as a conventional description of the assembled parts. Nāgasena applies the analogy to a person, arguing against an independent, unchanging self behind the bodily and mental constituents. The episode shows how the dialogue teaches through questions and familiar objects.

Plutarch gives a separate account of Menander’s death: he says that cities claimed portions of the king’s remains and raised monuments to house them. The story may recall Buddhist relic traditions, but it does not identify the monuments as stupas or independently prove that Menander was Buddhist.

Later Gandharan art developed many ways of representing Buddhist figures and stories, drawing on several visual traditions. Much of that surviving art belongs to periods after Indo-Greek kingship. Its history connects with the region’s earlier cultural contacts, but it requires its own chronology rather than attribution to a particular Greek ruler.
