The sacrifices of the Zoroastrians were never human. The ordinary victim was the horse; and we hear of occasions on which a single individual sacrificed as many as ten of these animals. Mares seem to have been regarded as the most pleasing offerings, probably on account of their superior value; and if it was desired to draw down the special favor of the Deity, those mares were selected which were already heavy in foal. Oxen, sheep, and goats were probably also used as victims. A priest always performed the sacrifice, slaying the animal, and showing the flesh to the sacred fire by way of consecration, after which it was eaten at a solemn feast by the priest and worshippers.
The Zoroastrians were devout believers in the immortality of the soul and a conscious future existence. They taught that immediately after death the souls of men, both good and bad, proceeded together along an appointed path to “the bridge of the gatherer” (chinvatperetu). This was a narrow road conducting to heaven or paradise, over which the souls of the pious alone could pass, while the wicked fell from it into the gulf below, where they found themselves in the place of punishment. The good soul was assisted across the bridge by the angel Serosh—“the happy, well-formed, swift, tall Serosh”—who met the weary wayfarer and sustained his steps as he effected the difficult passage. The prayers of his friends in this world were of much avail to the deceased, and greatly, helped him on his journey. As he entered, the archangel Vohu-mano or Bahman rose from his throne and greeted him with the words, “How happy art thou who hast come here to us from the mortality to the immortality!” Then the pious soul went joyfully onward to Ahura-mazda, to the immortal saints, to the golden throne, to Paradise. As for the wicked, when they fell into the gulf, they found themselves in outer darkness, in the kingdom of Angro-mainyus, where they were forced to remain and to feed upon poisoned banquets.
It is believed by some that the doctrine of the resurrection of the body was also part of the Zoroastrian creed. Theopompus assigned this doctrine to the Magi; and there is no reason to doubt that it was held by the priestly caste of the Arian nations in his day. We find it plainly stated in portions of the Zendavesta, which, if not among the earliest, are at any rate of very considerable antiquity, as in the eighteenth chapter of the Vendidad. It is argued that even in the Gathas there is an expression used which shows the doctrine to have been already held when they were composed; but the phrase adduced is so obscure that its true meaning must be pronounced in the highest degree uncertain. The absence of any plain allusion to the resurrection from the earlier portions of the sacred volume is a strong argument against its having formed any part of the original Arian creed—an argument which is far from outweighed by the occurrence of a more possible reference to it in a single ambiguous passage.
