(Ὀξάθρης), a Persian name, which is also written OXOATHRES and OXYATHRES, and is frequently confounded or interchanged both by Greek and Latin writers with OXARTES and OXYARTES. Indeed, it is probable that these are all merely different forms of the same name. (See Ellendt, ad Arrian. Anab. 3.8.8; Mützell, ad Curt. 8.4.21.)
