Libanius, the ablest Greek writer of the 4th century A.D., was born near Antioch about 315. His popularity as a teacher at Constantinople led to his expulsion in 346 on a charge of studying magic. He now passed five years in Nicomedia, and, after again spending some years in Constantinople, retired to his native place in 354, and died there in the last year of the century. Though a pagan, he was favoured by the Christian emperors, and was the teacher of St. Chrysostom and St. Basil.
