zucchetto

n. skullcap worn by Catholic priests

The zucchetto (plural zucchetti, Italian for "small gourd"), also called pileolus, is a small skullcap worn by clerics of the Roman Catholic Church and within Anglicanism (the Episcopal Church in the U.S.). It was first adopted for practical reasons — to keep the clergy's tonsured heads warm in cold, damp churches — and has survived as a traditional item of dress. It consists of eight panels sewn together, with a stem at the top. Its name may derive from its resemblance to half of a  pumpkin, or from the fact that it covers a larger "pumpkin" (the head).
