Lycophron (/ˈlaɪkəfrɒn/; Greek: ὁ Χαλκιδεύς) was a Hellenistic Greek tragic poet, grammarian, and commentator on comedy, to whom the poem Alexandra is attributed (perhaps falsely).
He was born at Chalcis in Euboea, and flourished at Alexandria in the time of Ptolemy Philadelphus (285-247 BC). According to the Suda, the massive tenth century Byzantine Greek historical encyclopaedia, he was the son of Socles, but was adopted by Lycus of Rhegium. He was entrusted by Ptolemy with the task of arranging the comedies in the Library of Alexandria; as the result of his labours he composed a treatise On Comedy. Lycophron is also said to have been a skilful writer of anagrams.
The poetic compositions of Lycophron chiefly consisted of tragedies, which secured him a place in the Pleiad of Alexandrian tragedians. The Suda gives the titles of twenty tragedies, of which a very few fragments have been preserved: Aeolus, Allies (Symmakhoi), Andromeda, Chrysippus, Daughters of Aeolus, Daughters of Pelops, Elephenor, Herakles, Hippolytus, Kassandreis, Laius, Marathonians, Menedemus, Nauplius, Oedipus (two versions), Orphan (Orphanos), Pentheus, Suppliants (Hiketai), Telegonus, and the Wanderer (Aletes). Among these, a few well-turned lines show a much better style than the Alexandra. Lycophron's tragedies are said to have been much admired by Menedemus of Eretria, although Lycophron had ridiculed him in a satyr play.
