SATURNALIA

Saturnalia was the ancient Roman festival of the god Saturnus. It was held in the middle of December from the 17th to the 19th and later until the 24th, and was originally a rustic harvest-home. It was a time of general holiday and merry-making and of the interchange of presents between friends, and the streets were full of joyous crowds, dressed not in formal toga, but in a loose robe called a synthesis.
