Dionysius of Halicarnassus (Greek: Διονύσιος Ἀλεξάνδρου Ἁλικαρνᾱσσεύς "Dionysios son of Alexandros of Halikarnassos"; c. 60 BC – after 7 BC) was a Greek historian and teacher of rhetoric, who flourished during the reign of Caesar Augustus. His literary style was Atticistic — imitating Classical Attic Greek in its prime.
