About

Indus is a constellation in the southern sky first professionally surveyed by Europeans in the 1590s and mapped on a globe by Petrus Plancius by early 1598. It was included on a plate illustrating southern constellations in Bayer's sky atlas Uranometria in 1603. It lies well south of the Tropic of Capricorn but its triangular shape can be seen for most of the year from the Equator. It is elongated from north to south and has a complex boundary. The English translation of its name is generally given as the Indian, though it is unclear which indigenous people the constellation was originally supposed to represent.

History and mythology

The constellation was created by Petrus Plancius who made a fairly large celestial globe from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman. The first depiction of this constellation in a celestial atlas followed in Johann Bayer's Uranometria of 1603. Plancius portrayed the figure as a nude male with three arrows in one hand and one in the other, as a native, lacking quiver and bow. It is among the twelve constellations introduced by Keyser and de Houtman, which first appeared on a celestial globe in 1598.
