Asterius of Amasea was a 4th-century bishop and orator from Cappadocia. Before his election to the episcopate, which occurred between 380 and 390 AD, he practiced as a lawyer. A contemporary of the Cappadocian Fathers, he was known for his rhetorical skill and lively preaching style. His surviving works, including sixteen homilies, provide significant historical insight into the social customs and daily life of the Byzantine Empire during his era.
