Why Jews are named Alexander

From the Alexander Mosaic

Some say that Alexander was great because of the length and width of his empire.  Jews say he was great because of its depth.

Alexander III of Macedon was a profound thinker.  It didn't hurt him any to have Aristotle (Maimonides' hero) as his personal tutor.

When Alexander conquered Tyre and Egypt via the Holy Land, he made it a point to visit with the High Priest of the Jerusalem Temple.  This visit is recorded by the Jewish historian Josephus, as well as in the Talmud.

Upon meeting the High Priest, Alexander is said to have immediately dismounted and bowed to him.  This induced General Parmenio to (boldly) ask Alexander for an explanation.  Alexander then answered: "I did not bow before him, but before that God who has honored him with the High Priesthood - for I saw this very person in a dream, in this very apparel."

Nevertheless, Alexander had the habit of putting effigies of himself within his conquered people's temples.  This did not sit well with the Jews.  They therefore offered a clever alternative - that of naming their children Alexander.  The idea stuck.  Thousands of years later, Jews are still being named Alexander.
