Being a modern constellation there is no mythology surrounding Triangulum Australe. The first depiction of the constellation appeared in 1589 on a celestial globe by the Flemish cartographer and astronomer Petrus Plancius, where it was called Triangulus Antarcticus and incorrectly placed to the south of the constellation Argo Navis, which has since been split into three smaller constellations. Johann Bayer gave the constellation the name Triangulum Australe in his Uranometria in 1603.
