Dyardanes

DYARDANES a large river of India, mentioned only by Curtius (Curt. 8.9.9). Forbiger conjectures, happily, that it is the same as the Brahmaputra, as no other river but it and the Ganges is likely to have nourished crocodiles and dolphins. Strabo (15. p. 719) gives a similar description of a river called the Oedanes (Οἰδάνης), which Grosskurd and others, without much reason, have supposed to be the same as the Iomanes of Pliny.

or Oedănes (Οἰδάνης). A great river of India (Q. Curt. viii. 9), possibly to be identified with the Brahmaputra.
