Waxing flustered, the teacher took him to a 10th grade history teacher who uses the same material. He claimed that many of these stories were recorded by Hesiod. Then he asked Antonio where he was getting his doubts. That explains it.
Classical scholars tend to defend the views of classical Greek patriarchy.
Later that afternoon I got a phone call at my office from Antonio's teacher. She said that this material was distributed to local IB teachers at a workshop eight years ago, and she has used it ever since. Sorry to bore you with all of this. Perhaps this is what many of you encounter when your kids finally meet the classical world in the public schools. But what's really uncanny in all this is that I happen to have been encountering a marginally more sophisticated version of the same thing in connection with my freshman Honors class.
