Saturnalia

Saturnalia became one of the most popular Roman festivals. It was marked by drunken orgies, tomfoolery and reversal of social roles, in which slaves and masters ostensibly switched places, much like the Lord of Misrule in later Christian celebrations.

Saturnalia was introduced around 217 BC to raise citizen morale after a crushing military defeat at the hands of the Carthaginians.[1] Originally celebrated for a day, on December 17, its popularity saw it grow until it became a week-long extravaganza, ending on the 23rd. Efforts to shorten the celebration were unsuccessful. Augustus tried to reduce it to three days, and Caligula to five. These attempts caused uproar and massive revolts among the Roman citizens.

Saturnalia involved the conventional sacrifices, a couch (lectisternium) set out in front of the temple of Saturn and the untying of the ropes that bound the statue of Saturn during the rest of the year. A Saturnalicius princeps was elected master of ceremonies for the proceedings. Besides the public rites there were a series of holidays and customs celebrated privately. The celebrations included a school holiday, the making and giving of small presents (saturnalia et sigillaricia), massive and multiple group orgies, and a special market (sigillaria). Gambling was allowed for all, even slaves.

The toga was not worn, but rather the synthesis, i.e. colourful, informal "dinner clothes"; and the pileus (freedman's hat) was worn by everyone. Slaves were exempt from punishment, and treated their masters with (a pretense of) disrespect. The slaves celebrated a banquet: before, with, or served by the masters. Yet the reversal of the social order was mostly superficial; the banquet, for example, would often be prepared by the slaves, and they would prepare their masters' dinner as well. It was license within careful boundaries; it reversed the social order without subverting it.[2]

The customary greeting for the occasion is a "Io, Saturnalia!" — Io (pronounced "e-o") being a Latin interjection related to "ho" (as in "Ho, praise to Saturn").
