Mitología de Equuleus

     In old times the constellation was already known Equuleus, was the babylonian time. On the contrary, the uncertain denomination is something, because neither Arato nor Hiparco mention to Equuleus, and only at the end of the Greek time it is when the first representation becomes of the region with the form of the nose of potrillo. The Latin legend  sees the Celeris horse there that Mercury donated Beaver. The pony is symbolized with the returned head but, on some old maps, the form of a sea horse plots to him  with a.  It exists, perhaps, in a this relation with the fact that the celestial zone follows by the east the dedicated one to the dolphin (Delphinus) and precedes to Aquarius (Aquarius), the fish (Piscis) and the whale (Cetus) which form an uninterrupted series of marine constellations.

           Equuleus, is the smallest constellation of the North hemisphere, indicated by five visible stars hardly at first, ready in delimited form of trapeze to the north and the west with Pegasus and Delphinus to the north and the east and  the south with Aquarius.  It crosses the parallel of North 10º, being visible in both hemispheres culminating during the month of August. One is next to the galactic equator for that reason she is rich in stars and accumulations, although the zone of the sky very is delimited. Objects of interest in Equuleus do not exist.
