The Gupta dynasty gold coin was named the dinara after the Roman denarius aureus - a reflection of Indian trading contacts with the West and the export of Roman coinage as bullion to India.
However, the designs of Gupta coinage were completely Indianized, and they were closely connected with the ancient Indian concept of a chakravartin (a universal monarch or ideal ruler).
This unique design shows a tethered horse. It symbolises the ashvamedha ritual of legitimizing the conquests of a honourable and pious king, in this case Kumaragupta I (around AD 415-50). After a great victory, a horse was left to roam for a year and all the lands he passed through in that time belonged rightfully to the king. At the end of the year the horse was sacrificed in celebration of the great king's victory.
The reverse of this coin shows a goddess (probably Lakshmi, the Hindu goddess of good fortune), with the royal attributes of a standard and a flywhisk.
