As evidence that Homer was a castrato, the Austrian academic cites three factors. First, the author of the Iliad perseverated almost too emphatically on normal sexuality, limiting the definition of the sexual act to that occurring between a man and a woman, depicting male fantasies about captive female slaves, and presenting motherly advice on why the bedding of females is good. From this contemporary investigator emerges an image of the author as a supreme homebody poring over scrolls on botany, or else a druid-like priest and, possibly, a eunuch. Second, such a deduction is consistent with the prevailing Assyrian tradition to appoint eunuchs as governors of Cilicia. No full beard appeared on the high-ranking sovereign writer, only a barely discernible fluff on his cheeks, which likely confirmed the poor fellow's castration.
Lastly, inherent to castrati is a physically agonizing bulimia, also intrinsic to the hero of the Iliad.
