StratComm, while I agree with your logic, I find your conclusion perhaps somewhat hasty. A myth often has an element of truth to it, somewhere in the core. Do not be so quick to dismiss the myth as naught but a petty story.
That doesn't mean that you are necessarily wrong, merely perhaps a tad quick to judge the situation. In fact, I too rather doubt that Plato's account is entirely accurate. But there may, in the end, be a core of truth to the legend he wrote down. After all, Troy was a myth, dismissed for centuries, until one man's fascination found that old city of wooden walls. And all of this is said in an academic sense, no insult is intended, merely an interesting scholarly discussion. Preferrably with mutual respect on both sides.
In any case, this should be fascinating to see how it plays out. This is one of the more interesting leads I've seen explored.
