well, Chris Columbus may very well have been of Jewish origin, but his religious beliefs are of course, open to speculation despite the fact that he was outwardly a devout Christian.
I think this jockeying over pride is senseless. We can’t take credit for our parents actions, leave alone by co-religionists.
One of my favorite books is “The Velvet Doublet”, by James Street, describing fictional events surrounding Columbus.
I don’t recall Columbus being labeled a jew but do recall that the first sighting of land from the ship’s crow’s nest was made by a Moor.
