According to the Greek mythology Celeris is the name with which it is known to "Equuleus" - minor horse or colt - the smaller brother of Pegaso that gave Hermes to Cástor.
According to the Latin version, Pegasus is not the older brother but the father of Celeris, being Pegasus the horse that was born as the fruit of the blood of the Medusa Gorgon to be beheaded by Perseus.
According to classical sources, Perseus did not even fly Pegasus, since he did so thanks to winged sandals. Astronomy
At present, Celeris or Equuleus is known as a small constellation of the northern hemisphere, near the celestial equator, located between Pegasus and Delphinus, just north of Aquarius.
Its brightest star is called Kitalpha, an Arabic name meaning "little horse." Its location next to Pegaso is not surprising because, during the end of the Greek era the first representation of the region was made with the shape of a foal's nose. It is the Latin legends that place there the horse Celeris that Mercury donated to Castor.
Catasterism is the mythological transformation of a character into a star or a constellation in Greek mythology. In the case of Celeris, his catasterismo corresponds with the constellation of Ecúleo.
