History

The origin of this constellation is mostly attributed to Johann Bayer in his Uranometria from 1603, the first atlas of the entire sky. He had taken it from the records of numerous sailors in the southern hemisphere from the previous century, including Amerigo Vespucci. Bayer formed a total of twelve new constellations. [7]
