Halicarnassus was a city on the southwestern shore of what is now Turkey. Dionysius was a Greek historian who lived there in the first century B.C., dying in 7 B.C. He settled in Rome about 29 B.C. and wrote a history of Rome in twenty volumes, half of which still exists. It was his avowed purpose to write a panegyric (high praise in verse) of the Romans in order to reconcile the Greeks to being ruled by them.
