The Venetian Council passed the law, and must have used the word. I saw the foundry just
called "geto". No clue as to where the "h" came from. And each of the European and Levantine
Jewish factions were represented. I'm sorry I didn't keep the History URL. I'll find it again, I've
little else to do at the moment.

P.S.
According to tradition, the name "ghetto" is derived from the Venetian word "geto", meaning foundry which was pronunced
with a hard "g" by the German Jews, who first settled here. The first zone assigned to the Jews was called "Ghetto Nuovo"
because there was a new foundry there; "Ghetto Vecchio", named for the old foundry, was the second zone granted to the
Jews, after 1541; finally, "Ghetto Novissimo" was the area given in 1633.
