One of twelve southern constellations mapped by Dutch explorer Frederick de Houtman and navigator Pieter Dirkszoon Keyser in 1595-97, formed into constellations by Dutch astronomer Petrus Plancius, and introduced to the world at large by Johann Bayer, in his 1603 Uranometria. Most of the stars in Grus were listed by Ptolemy, as part of Piscis Austrinus; so Grus was a new constellation, but to a certain extent, merely a division of an old one. |
