Nagasena

Nāgasena was a Sarvāstivādan Buddhist sage who lived around 150 BC. His answers to questions about Buddhism posed by Menander I, the Greek king in northwestern India, are recorded in the Milindapañhā and the Sanskrit Nāgasenabhiksusūtra. According to Pali accounts, he was born into a Brahmin family in the Himalayas and was well-versed in the Vedas at an early age. However, he later converted to Buddhism.
