Dorado was one of twelve constellations named by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman,[1] and it first appeared on a 35-cm diameter celestial globe published in 1597 (or 1598) in Amsterdam by Plancius with Jodocus Hondius. Its first depiction in a celestial atlas was in Johann Bayer's Uranometria of 1603 where it was also named Dorado. Dorado has been represented historically as a dolphinfish and a swordfish; the latter depiction is inaccurate.[2] It has also been represented as a goldfish.[1] The constellation was also known in the 17th and 18th century as Xiphias, the swordfish, first attested in Johannes Kepler's edition of Tycho Brahe's star list in the Rudolphine Tables of 1627. The name Dorado ultimately become dominant and was adopted by the IAU.
