Hesychius

Hesychius, a grammarian of the fourth century A.D., is supposed to have been a native of Alexandria. He produced a Lexicon, partly original and partly compiled from older ones. It is considered the best of the early lexicons, and has great antiquarian value. A good edition was published at Leyden in 1746-66, and the supplements of Schow, Leipzig (1792), and of Schmidt, Jena (1857-64), are of value.
