Nagasena

Nāgasena was a Buddhist sage who lived about 150 BCE. His answers to questions about Buddhism posed by Menander I (Pali: Milinda), the Indo-Greek king of northwertern India, are recorded in the Milinda Paņha.

The text mentions that Nagasena learned the Tripitaka under the Greek Buddhist monk Dhammarakkhita near Pātaliputta. He also reached enlightenment and became an arhat under his guidance.

Other personalities mentioned in the text are Nāgasena's father Soņuttara, his teachers Rohaa, Assagutta of Vattaniya and another teacher named Āyupāla from Sankheyya near Sāgala.

Nagasena is not known through other sources besides the Milinda Panha.
