Acesias

Acesias (Greek '''''') was an ancient Greek physician whose age and country are both unknown.

It is ascertained however that he lived at least as early as 4th century BC, as the proverb , "Acesias cured him", is quoted on the authority of Aristophanes. This saying (by which only Acesias is known to us) was used when any person's disease became worse instead of better under medical treatment, and is mentioned in the Suda, Zenobius, Diogenianus, Michael Apostolius, and Plutarch.
