Concerns Origin of the Name
Currently States What the twins originally stood for has been read as the two twilights, the morning and evening star, the sun and moon, day and night, and a pair of stars.
The Ashwini Kumaras, the twin horsemen gods of the Rigveda, have a name whose origin was already disputed within the Indian commentarial tradition before European Indology took up the question in the nineteenth century. Arthur Anthony Macdonell's Vedic Mythology (1897) records that classical Indian commentators on the Rigveda had already recorded rival explanations of the name ashvin, from the Sanskrit root for horse, and its connection to the twins' equine associations and to competing identifications of what natural phenomenon, dawn and dusk, morning and evening stars, or the sun and moon, the pair might represent. The method from Macdonell onward is philological, comparing the twins' epithets and mythic episodes across the Rigveda's hymns against each candidate identification, and no single proposal has since carried the field, ancient or modern. Because real, readable positions exist on both sides of a debate older than modern scholarship itself, the entry is recorded as argued rather than as an unexamined blank.
