From: The History of Rome, by Theodor Mommsen
Translated with the sanction of the author by William Purdie Dickson
An unexpected light has been thrown on various enigmatical forms in the Greek mythology by recent researches regarding the earlier divinities of India. The hoary mysterious forms of the Erinnyes are no Greek invention; they were immigrants along with the oldest settlers from the East. The divine greyhound Sarama, who guards for the Lord of heaven the golden herd of stars and sunbeams and collects for him the nourishing rain-clouds as the cows of heaven to the milking, and who moreover faithfully conducts the pious dead into the world of the blessed, becomes in the hands of the Greeks the son of Sarama, Sarameyas, or Hermeias; and the enigmatical Greek story of the stealing of the cattle of Helios, which is beyond doubt connected with the Roman legend about Cacus, is now seen to be a last echo (with the meaning no longer understood) of that old fanciful and significant conception of nature.
