Corona Australis constellation
Corona Australis is nowadays recognized by IAU and listed in 88 modern known constellations. Corona Australis is the counterpart to Corona Borealis. Corona Australis is a small inconspicuous constellation located between Sagittarius and Scorpius in the southern hemisphere. Its name is Latin and means “Southern Crown”. Corona Australis is called Southern crown because it represents the crown that was worn by a centaur. The constellation is not linked to any particular myth story.
Greeks didn’t see it as a crown but as a laurel wreath. That story is associated with the Dionysus who was supposed to have placed a wreath of myrtle into the Underworld. That was actually a gift for his dead mother. The small circlet of dim stars this constellation contains has an appearance of a wreath or a crown.

Mythology of the Corona Australis constellation
Corona Australis or also known as the Southern Crown was first documented by the Greek astronomer Ptolemy in the 2nd century CE. Corona Borealis, that was also in Ptolemy’s list of then-known 48 constellations, is actually the Northern Crown.
In one version of the story is Corona Australis constellation associated with the myth of the God Dionysus. Corona Australis is here shown as the crown that Dionys’ placed in the sky after freeing his mother Semele from Hades. In another, Corona was known as a wreath and not as a crown.
Long before Ptolemy’s list of constellations was created, The Corona Australis Constellation was known as a circlet of stars near Centaur’s forefeet and was represented by Zodiac constellation Sagittarius. 13 stars were originally added to this constellation by Ptolemy, but later one was one of them moved to Telescopium and shortly became its Alpha star.
