Explanation
Why Correct: Agathocles, an Indo-Greek king who ruled around 190–180 BCE, issued a series of coins depicting the Hindu deities Krishna and Balarama. These coins are significant as some of the earliest numismatic evidence of Vaishnavism in the Indian subcontinent, showing the cultural synthesis between the Greeks and Indians.
Distractor Analysis: Menander (Milinda) is the most famous Indo-Greek ruler, known for his conversion to Buddhism and his dialogue with the Buddhist monk Nagasena, recorded in the Milindapanha. Heliocles was one of the last Indo-Greek kings, ruling in Bactria, and is known for his portrait coins rather than religious depictions. Archebius was a later Indo-Greek king who ruled in the Gandhara region, and his coins typically feature Greek deities like Zeus and Athena.
Takeaway: The Agathocles coins are also notable for depicting the goddess Lakshmi and a six-headed Kartikeya, making them a key source for understanding the spread of Indian religious iconography in the Hellenistic world.
