Aria: Ô toi, Palermo (‘O, Palermo)’). [This character is based on the real Procida, a distinguished doctor born in Salerno and physician to Emperor Frederick II. Through his involvement in politics he became a conspirator of international repute and appears in history books.] Created (1855) by Louis‐Henri Obin.
