CETUS (sea monster of Greek myth)

Brought up from the misty South, the creature pressed against Andromeda due to the rush of the sea.^2,1 Cepheus warned the beast back with his mighty hand upraised.² The monster set below the horizon with his neck pointing downward, while his neck and tail rose from below when the Bull constellation ascended.^2,3

Fully visible above the horizon when the Twins constellation rose, Cetus sat slightly above the Starry River.^3,1 A bright star lay beneath the tail of the dark-blue creature, which was intersected by a specific southern celestial circle.^4,5 A single star marked the meeting point of his spine and head, and the Shackles joined together behind his neck.¹

The remains of Cetus were visible in the sky alongside the remains of Andromeda until the Scorpion constellation rose, causing the monster to flee.⁶
