Agathosthenes (Ἀγαθοσθένης) was a Greekhistorian or philosopher of uncertain date,[1] who is referred to by Tzetzes as his authority in matters connected with geography.[2] There is mention of a work of Agathosthenes called "Asiatica Carmina",[3] where some writers read the name "Aglaosthenes";[4] for Aglaosthenes or Aglosthenes, who is by some considered to be the same as Agathosthenes, wrote a work on the history of Naxos, of which nothing remains, but which was much used by ancient writers.[5][6][7][8][9]
