Ichthyocentaur
In late Classical Greek art, an ichthyocentaur (Ancient Greek: ἰχθῠοκένταυρος, plural: ἰχθῠοκένταυροι, romanized: ikhthúokéntauros, ikhthúokéntauroi) is a centaurine sea being with the upper body of a human, the lower anterior half and forelegs of a horse, and the tailed posterior half of a fish. The earliest example dates to the 2nd century BC, among the friezes in the Pergamon Altar.
