About the year 300 it became plain that a new religion was spreading through the eastern provinces of the Roman Empire. This was the faith taught by one Manes or Mânî, a native of Babylonia, who was put to death by order of the Shah Bahram or Varanes I in 275. One story is that he began to teach when 13 years old, another when he was 24. We know with fair certainty that he was 60 when he died; so that if we take the more probable date his missionary activity must have lasted for thirty-five years— a longer period than has generally been allowed to founders of new religions. His teaching must also have started in the reign of Ardeshîr, the restorer of the Zoroastrian religion, by whose orders were collected the books known as the Avesta. Ardeshîr's religious restoration was avowedly made for political reasons, and with the view of binding together the newly-founded empire of the Sassanides by a common faith. It seems to have given a good deal of offence to the older Persian nobles, and it was very likely among these that Mânî found his first converts. The later Manichæans boasted that he converted to his doctrines Ardeshîr's successor, Shâpûr or Sapor, the conqueror of the Emperor Valerian, and also the next king, Hormuz or Hormidas, who reigned only a few months.
