Hermippus of Berytus, also known as Hermippus Berytius or Hermippus the Berytian[1] (Greek: Ἕρμιππος ὁ Βηρύτιος; fl. 2nd century AD) was a Greek grammarian from Berytus (modern-day Beirut) who flourished under Trajan and Hadrian. By birth he was a slave, but having become the disciple of Philo of Byblos, he was recommended by him to Herennius Severus, and attained to great eminence by his eloquence and learning.[2] He wrote many works, among which were an account of dreams in five books,[3] and a book Περὶ Ἑβδομάδος.[4] He wrote a work on famous slaves,[5] which included Parthenius of Nicaea.[6] He is also quoted by Clement of Alexandria,[7] and by Stephanus of Byzantium.[8]
