Ašvieniai are divine twins in the Lithuanian mythology, identical to Latvian Dieva dēli and the Baltic counterparts of Vedic Ashvins. Both names derive from the same Proto-Indo-European root for the horse - *ek'w-: Old Lithuanian ašva and Sanskrit ashva mean horse. Like the Greek Dioscuri Castor and Pollux, they are reflexes of a common Indo-European mytheme, the Divine Twins.
