Nagasena
Nāgasena was a Sarvāstivādan Buddhist sage who lived around 150 BC. His answers to questions about Buddhism posed by Menander I (Pali: Milinda), 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.
