Accusative for dative with "latere" in Medieval Latin? From: Dolopathos sive de rege et septem sapientibus of Joannes of Alta Silva (c. 1200); in "A Primer of Medieval Latin" by Charles H. Beeson" ; Page 98, line 29.
"Quod tamen eum non latuit, quia iam antea ...."
If "eum" (acc) was used with "latere" in ML for "ei" (dat) in CL, then it could be translated as ".....it was not unknown to him ....."; yet I don't see this mentioned in the summary of medieval grammar in the introduction of Beeson's book.
