Daniel chapter 11:1-6 Interpretation errors

I don't know who started the wrong interpretation referencing King Alexander the Great as the "mighty king" n Daniel 11:30. Using AI to do some research, one AI says it began with Josephus in the later part of 100 C.E., Another AI says it began with St Jerome who lived in the later part of the 300's A.D.. Either way, they didn't have close to the better perspective of last-days events compared to us today.
