Coppola (cap) courtesy of wikipedia
The coppola is a traditional kind of flat cap typically worn in Sicily. First used by English nobles during the late 1700s, the coppola began being used in Sicily in the early 1900s as a driving cap, usually worn when at the wheel driving the car. The coppola is usually made in tweed.
The origin of the name coppola is likely to be a Sicilian adaptation of the English word cap. By extension, coppola is also Sicilian for head. The word coppola then became popular also in the rest of Italy, and was quickly acquired by Italian language by extension. Today, the coppola is widely regarded, at least in Italy, as a definitive symbol of Sicilian heritage.
