In the Odyssey,[381] Ulysses goes to consult the diviner Tyresias; and this sorcerer having prepared a grave full of blood to evoke the manes, Ulysses draws his sword, and prevents them from coming to drink this blood, for which they appear to thirst, and of which they would not permit them to taste before they had replied to what was asked of them; they (the Greeks and Latins) believed also that souls were not at rest, and that they wandered around the corpses, so long as they remained uninhumed.[382] When they gave burial to a body, they called that _animam condere_,[383] to cover the soul, put it under the earth and shelter it. They called it with a loud voice, and offered it libations of milk and blood. They also called that ceremony, hiding the shades,[384] sending them with their body under ground. The sybil, speaking to AEneas, shows him the manes or shades wandering on the banks of the Acheron; and tells him that they are souls of persons who have not received sepulture, and who wander about for a hundred years.[385] The philosopher Sallust[386] speaks of the apparitions of the dead around their tombs in dark bodies; he tries to prove thereby the dogma of the metempsychosis. Here is a singular instance of a dead man, who refuses the rite of burial, acknowledging himself unworthy of it. Agathias relates[387] that some pagan philosophers, not being able to relish the dogma of the unity of a God, resolved to go from Constantinople to the court of Chosroes, King of Persia, who was spoken of as a humane prince, and one who loved learning. Simplicius of Silicia, Eulamius the Phrygian, Protanus the Lydian, Hermenes and Philogenes of Phoenicia, and Isidorus of Gaza, repaired then to the court of Chosroes, and were well received there; but they soon perceived that that country was much more corrupt than Greece, and they resolved to return to Constantinople, where Justinian then reigned. As they were on their way, they found an unburied corpse, took pity on it, and had it put in the ground by their own servants. The following night this man appeared to one of them, and told him not to inter him, who was not worthy of receiving sepulture; for the earth abhorred one who had defiled his own mother. The next day they found the same corpse cast out of the ground, and they comprehended that it was defiled by incest, which rendered it unworthy of the honor of receiving burial, although such crimes were known in Persia, and did not excite the same horror there as in other countries.
