The Indian , or Indian Oiseau is a Constellation of the Southern hemisphere. The area which it covers, near to the pole southern celestial, is relatively low in star S and little are visible with the naked eye. The meaning “Bird Indian” is relatively not very frequent, because of the risks of confusion with the constellation of the Bird of paradise.
History
The Indian is a constellation probably invented by the navigator S Dutch Pieter Dirkszoon Keyser and Frederick de Houtman at the end of the 16th century and introduced by Johann Bayer into his Uranometria in 1603.
It is supposed to represent a Indien of America, that Bayer wanted to honor with a place on the vault of heaven.
The Astronome Julius Schiller combined the Indian and the Paon in order to form a constellation that it named according to the biblical character Job. This constellation - as all other religious creations of Schiller - did not meet success on the long run.
