The Greek witness gives the motif its full sentence: crime, commutation, service. Apollo, avenging Asclepius, "slew the Cyclopes who had fashioned the thunderbolt"; Zeus "would have hurled him to Tartarus" but at Latona's plea "ordered him to serve as a thrall" to a man for a year [The Library (Bibliotheca), BOOK III, ch. X]. "So he went to Admetus, son of Pheres, at Pherae", and even in servitude divinity leaks: the divine herdsman "caused all the cows to drop twins" [ibid.]. Frazer's note widens the file: by one account "the motive for Apollo’s servitude was his love for Admetus", and "Apollo is said to have served Branchus as well as Admetus" — the humiliation is a habit [ibid., editor's note]. The candidate lane offered a second tradition, and it dissolves on reading: the Mahābhārata hit is Brahman's caste-charter, ordaining that "the Sudra should serve the three orders as a menial" — men serving men, no god in exile [The Mahābhārata, Book 12, Section LXXII]. Keyword "menial", wrong subject: this motif needs a master who is mortal and a servant who is not.
