“ All Parsis wear the sacred thread of serpent and phallic extraction, and the investiture of this is a solemn and essential rite with both sects [i.e., the Hindus and [565] Parsis] , showing their joint Aryan origin in high Asia, for the thread is of the very highest antiquity. The Parsi does not, however, wear his thread across the shoulder, and knows nothing of the all-but-forgotten origin of its required length. ”
