The fact that his cosmology shares themes with those of Western Asia does not prove that he knew of the latter. I saw 10 Things I Hate About You years before I ever read, or became familiar with the Taming of The Shrew. I became familiar with the common themes of the stories through my exposure to the adaptation, not the originals. Had I never subsequently heard of the Taming of the Shrew, I would have remained familiar with those themes. I see no reason why Hesiod’s own familiarity could not stem from myths adapted from Eastern sources, allowing him familiarity with the themes despite having never seen the originals.
