And so, the Romans stand apart from the majority of the ancient peoples, in so far as the belief in Reincarnation is concerned. While there were individual mystics and occultists among them, it still remains a fact that the majority of the people held no such belief, and in fact the masses had no clearly defined ideas regarding the survival of the soul. It is a strange exception to the general rule, and one that has occasioned much comment and attention among thinkers along these lines. There was a vague form of ancestor worship among the Romans, but even this was along the lines of collective survival of the ancestors, and was free from the ordinary metaphysical speculations and religious dogmas. Roughly stated, the Roman belief may be expressed by an idea of a less material, or more subtle, part of man which escaped disintegration after death, and which in some mysterious way passed on to combine with the ancestral soul which composed the collective ancestral deity of the family, the peace and pleasure of which were held as sacred duties on the part of the descendants, sacrifices and offerings being made toward this end. Nevertheless, here and there, among the Romans, were eminent thinkers who seemingly held a vague, tentative belief in some form of Reincarnation, as, for instance, Ovid, who says: "Nothing perishes, although everything changes here on earth; the souls come and go unendingly in visible forms; the animals which have acquired goodness will take upon them human form"; and Virgil says: "After death, the souls come to the Elysian fields, or to Tartarus, and there meet with the reward or punishment of their deeds during life. Later, on drinking of the waters of Lethe, which takes away all memory of the past, they return to earth." But it must be admitted that Rome was deficient in spiritual insight and beliefs, on the whole, her material successes having diverted her attention from the problems which had so engrossed the mind of her neighbor Greece, and her older sisters Persia, Chaldea, and Egypt.
