Saturnalia

Saturnalia is a Roman celebration between December 17th and 23rd. It's held in honour of Saturn, a god of wealth and agriculture. We have echoes of the Roman celebration today with the decourative tree, gingerbread men, giving eachother gifts, kissing under the mistletoe, sweets, role reversal in pantomimes, feasts, white candles, games, Santa's hat, music and wild parties.
The Greek version of Saturn was Cronus and he ate his own children. He's often connected with two women, Ops and Lua. Ops is the wife and sister of Saturn. She's an Earth daughter and her Greek counterpart is Rhea. Lua is a mistress of Saturn and she represents destruction and war.  
During Saturnalia, was the season of misrule, chaos and sexual violence, people in various communities ran riot. Animals were sacrificed. Some people have said humans were sacrificed but other sources refute that. Leaving human ritual sacrfice out, the celebration was when rules broke down only for that time, slaves were allowed to bully their masters, people could wear whatever they liked, many wore masks,  and people sang naked in the streets. People drank, ate and gambled. What they did only lasted for a short time and afterwards everything returned to normal.
