kṛśāśvasya tu devarṣer devapraharaṇāḥ sutāḥ //

The twenty-seven daughters of the patriarch who became the virtuous wives of the moon were all known as the nymphs of the lunar constellations, which were called by their names, and had children who were brilliant through their great splendour. The wives of Arisht́anemi bore him sixteen children. The daughters of Bahuputra were the four lightnings. The excellent Pratyangirasa Richas were the children of Angiras, descended from the holy sage: and the deified weapons of the gods were the progeny of Kriśáśwa.
