Triangulum Australe - Southern Triangle

The Southern Triangle is much more noticeable than its northern (the original) cousin. It was first recognized by Bayer, who published news of its existence in 1603. Supposedly it honored the three patriarchs, Abraham, Isaac, and Jacob. It lies south of Ara and Norma between the tail of Pavo and the front feet of the Centaur.
