This is the best-known of the Venetian masks. It is said his name derives from San Pantaleone, one of the city's most venerated saints after whom a church is even named. Others say the name comes from 'Piantaleoni' referring to the merchants who went to 'plant the lion' of San Marco in conquered lands.

Pantaloon is an old merchant, he is still a very special old man because, despite his age he is still capable of making amorous advances which never conclude in a positive way.

The costume consists of a Greek woolen cap, a red jacket, short belted breeches with a sword, or a hanky or a bag hanging form the belt. He wears a black cloak over his shoulders, lined with red on the inside, black slippers or Turkish babouches with the ends pointing upwards. The mask reveals a large hooked nose, accentuated eyebrows and a curious goaty beard, which he usually strokes with his fingers.

The Pantaloon costume is amongst the most popular during the carnival period.
