Merry Saturnalia

Today is the anniversary of the first Saturnalia per Wikipedia:

497 BC – The first Saturnalia festival was celebrated in ancient Rome.

Saturnalia was the celebration of the dedication of the Temple of Saturn. Saturn (in addition to being a planet) was a Roman god who represented generation, dissolution, plenty, wealth, agriculture, periodical renewal, liberation, and time. (He was kinda a dick, too.)
Saturnalia was celebrated with "a public banquet, followed by private gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms... ."
Huh. Sounds a lot like Christmas.
