Crater - Cup

“Wise ancient knew when Crater rose to sight,

Nile’s fertile deluge had attained its height.”

The cup is formed above Hydra’s back just westward of Corvus and 30° south of Denebola. For that reason it often was considered part of a constellation called Hydra et Corvus et Crater. Today they are catalogued separately.
