Dinon in Wikipedia
Dinon or Deinon (Greek Δίνων or Δείνων) of Colophon (c. 360 BC – 340 BC) was a Greek historian and chronicler, the author of a history of Persia, the Persica (Greek Περσικα), many fragments of which survive. The Suda mistakenly attributes this work to Dio Cassius. He is the father of Cleitarchus.
He takes the history of the near East from where Ctesias leaves off, and, while indulging in the taste for the low, was held in considerably more regard than that author's Persica.
