Erinys.

The Furies, the Eumenides, the Erinys are well known from Greek mythology and tragedy (they chased the matricide, Orestes, driving him mad). It occurs in Mycenaean as e-ri-nu. EIEC relates this to PIE *seren(w)uhxs, 'name of a goddess'. This is also related to the Old Indic goddess, Saranyu. This is from the article 'Goddesses (Misc) by Edgar Polome (p. 232).

Saranyu is the daughter of the divine craftsman Tvastr and the wife of the Sun, to whom she bears the twins Yama and Yami. She ran away, taking the shape of a mare and leaving in her stead Savarna, a woman of similar appearance, with whom her husband Vivasvat (the shining one = the rising sun) begets Manu. When Vivasvat discoveres how his actual wife escaped him, he assumes the form of a stallion, and arouses the desire of the mare Asvini, as Saranyu is now called. They mate and give birth to the Asvins.

Polome has no problems with the etymology, but objects to identifing Saranyu with the Erinys. They are separate developments.
