Milindapanho is in the form of a dialogue between the King Menander and the Buddhist monk

The Milindapañha (Milinda Panha) is conventionally presented as a series of questions posed by the Indo-Greek king Milinda (Menander) and answered by a senior Buddhist monk named Nagasena; standard textbook treatments identify the dialogue specifically between Menander and Nagasena [1]. Scholarly and source introductions to the text likewise describe it as a compilation of questions from King Milinda with replies by the monk Nagasena, treating Nagasena as the primary interlocutor who explains key Buddhist doctrines such as anatta using analogies like the chariot simile [2]. The other names listed (Nagarjuna, Nagabhatta, Kumarilabhatta) are not associated with this Pali dialogue.
