Quarantine is derived from the Venetian (and Italian) word for forty, because the quarantine period on the Lazzaretto Nuovo ended up around forty days.
Ciao – the Italian informal salute – is actually Venetian, and has its roots in the medieval slave trade.
The Venetian lawmakers voted by casting a small ball in a vase. That ball, a balote, became a ballot in the United States.
The word “Lazaret” (“Lazzaretto” in Italian) comes from the original name of the medieval plague hospital in the Venetian Lagoon.
