(Μαισῶλος; Maisôlos). Indian river, has its source in the Orudia mountain range (unclear according to ) and flows south to the Gulf of the Ganges (Ptol. 7,1,15; 37). Either modern Godavari or rather Kistna (Krishna) at whose delta the city of Masulipatam still lies today. Dey  also equates the name of the river M. with Old Indian Mahāósāla, a place of pilgrimage on the Godavari.
