Page "Equuleus" Paragraph 5

In Greek mythology, one myth associates Equuleus with the foal Celeris ( meaning " swiftness " or " speed "), who was the offspring or brother of the winged horse Pegasus.

Celeris was given to Castor by Mercury.

Other myths say that Equuleus is the horse struck from Poseidon's trident, during the contest between him and Athena when deciding which would be the superior.

Because this section of stars rises before Pegasus, it is often called Equus Primus, or the First Horse.

Equuleus is also linked to the story of Philyra and Saturn.
