It has, however, been considered most probable that it is the same as the Sonus of Pliny, the modern Soane, though both that author, as well as Arrian, speaks of two rivers, which they call respectively Erannoboas and Sonus. The name was probably derived from the Sanscrit Hyranyavahas, the poetical name of the Sonus.
