Very good! I loved it. The note in the end is a good idea, because the pedantic side of me was rearing its ugly head and frowning at the tablets, the punctuation and the Eros business. :) But this is fanfiction, after all: we are allowed some liberties. Besides, Homer himself slipped into quite a few anacronisms in the Iliad and that doesn't change anything to the fact that it's one of the greatest pieces of literature ever written.
Your Telemachus is not only historically accurate, it's also a pretty good portrait of a boy growing into a man in the ever-present absence of his father, taken from him to fight on somebody else's war.
