Aśvini (अश्विनी) is the name of an Indian twin deity that is asscoiated with the first nakshatra. As gods they initially represent physicians; as asterism they are associated with the star β and γ Arietis in Aries. However, the oldest reconstruction of the image shows a horse head with three stars, suggesting that α Arietis might also have belonged to the asterism.

Origin of Constellation
