The Heliodorus pillar is a stone column that was erected around 113 BCE in central India[43] in Vidisha near modern Besnagar, by Heliodorus, an ambassador of the Indo-Greek king Antialcidas in Taxila[44] to the court of the Shunga king Bhagabhadra. Historically, it is one of the earliest known inscriptions related to the Vaishnavism in India.[45][46][47]
