Apus (Latin for bird of paradise or swallow, from Greek απους, lit. "no-feet") is a faint southern constellation, not visible to the ancient Greeks. The constellation was one of twelve constellations created by Pieter Dirkszoon Keyser and Frederick de Houtman between 1595 and 1597, and it first appeared in Johann Bayer's Uranometria of 1603.
