In many cases, a mythos can be seen as an allegory. For example, the biblical episode of Judith and Holofernes can be seen as the eradication of pride, accomplished at all costs, emphasizing the problem of superbia and the importance of its removing. The decapitation theme associated with the annihilation of pride can be also found in the Greek, Mesopotamian and even Kurdish tradition, and most likely in others I am not aware of.
Going back to my question after having defined what I am looking for, is there any allegorical reading of the destruction of Troy? That is, has any mythologist or philologist found any, so to speak, metaphysical (Aristoteles is turning in itshis tomb right now) interpretation of the leveling of the Dardan city?
