I nearly forgot - today (the 17th) is the first day of the Roman Saturnalia. Apologies if this has been mentioned already today...

This day (NP), is for special religious observance.
This is the first day of the Saturnalia. The Saturnalia honors Saturn (Cronus) and is one of the most festive and uninhibited that the ancient Romans celebrated. It went on for seven days and encompassed the Winter Solstice, a time of religious observance for cultures the world over. Feasts were provided by the temples and were open to the public, the poor and the homeless. Servants and masters were met on equal terms. Unable to prevent the people's natural festive inclinations at this time of year, early Christian leaders, clever Greeks that they were, moved Christmas to December and claimed the celebration for their own.
During the Saturnalia, rules were set aside, schools were closed, and slaves could meet their masters on equal terms. Human kindness was the theme and war and the punishment of criminals was halted. The exchange of gifts was universally practiced. Strenae, which were boughs to which were attached cakes or sweetmeats, were exchanged by visitors and guests. Other common gifts included wax candles (cerei) and sigillaria, which were doll-like clay figures, a particular favorite of children.
