From the 3rd ed. of the American Heritage Dictionary: Saint Pantaleon was so closely associated with Venice that the Venetians were nicknamed Pantaloni by other Italians. In plays, the stereotypical Venetian merchant was called Pantalone. The French identified Pantalone with a particular style of trousers, which was transferred to English as pantaloons. Pantaloons later referred to trousers in general, and in the 19th century was shortened to a vulgar 'pants.'
The original name is "Panteleimon" and means "protection".

This name reminds me too much of the Spanish word "pantalones" (which means pants) and the English word "pantaloon" (which means pants or an aging, senile person).
