Agias or Hagias was an ancient Greek poet, whose name was formerly written Augias through a mistake of the first editor of the Excerpta of Proclus. This misreading was corrected by Friedrich Thiersch, from the Codex Monacensis, which in one passage has "Agias", and in another "Hagias". The name itself does not occur in early Greek writers, unless it be supposed that the "Egias" or "Hegias" in Clement of Alexandria and Pausanias, are only different forms of the same name.
