These naïve scenes decorated, as we have said, a burial place. Many other tombs are not so elaborate, but express the same symbolism by opposing the hard labour of man, represented on the lower part of the stele, to the rest which this same man enjoys on the upper part of the stone, that is, in heaven.[362] The symbol of the Y was early applied to the future life by the Pythagoreans, who transferred the roads representing the courses of the moral and the immoral life to Hades. Their stories of the descent to the nether world depicted the journey of the dead in the same way, and it is still thus described in the sixth book of the Aeneid. The dead first follow a common road; and those whose lot is still undetermined wait in this first abode, just as on earth children are not yet separate at the uncertain age at which they have not yet made their decision for virtue or for vice. At the crossroads of earthly existence the choice must be made; at the crossroad of the infernal regions (τρίοδος) the judges of souls are seated,[363] and send to the right those who have by their merits made themselves worthy to enter the Elysian Fields, while they drive to the left the wicked who are to be hurled into Tartarus. For in both worlds “right” is to the Pythagorean, as to the soothsayers, synonymous with “good,” and “left” synonymous with “evil.” The original conception was necessarily transformed and explained symbolically when the abode of virtuous souls was transported to heaven. The stories of the ancients were no longer taken in their literal sense, but an allegorical meaning, allowing them to be brought into harmony with the new beliefs, was given to them. Henceforward one of the two roads leads to the higher regions, the road, namely, of the Blessed (ὁδὸς μακάρων) or of the gods. The other, the path of men, is that which after long windings brings back to earth the impure souls who accomplish the cycle of their migrations and must be reincarnated in new bodies.
