Mythology and History
Crater is an ancient constellation that represents the golden chalice of Apollo and is associated with the neighboring Corvus in the legend. In the course of the Christianization of the sky, the constellation was renamed to one of the stone water jugs of Cana, but also to the chalice of the passion of Christ, in vain. [7, 20]
