There are no myths associated with Indus. This southern constellation was one of 12 constellations created by the Dutch astronomer Petrus Plancius based on the observations of Dutch navigators in the 16th century. It was first depicted in Johann Bayer’s star atlas which was published in 1603. It was depicted as naked male figure holding arrows in both hands. It is believed to represent the indigenous people that explorers encountered during their travels to the East Indies, Madagascar, and southern Africa.
