The Ancient Roman Festival of Saturnalia began as a one-day festival in honor of the Roman god Saturn, but by the late Republic, it spanned over an entire week.
The Saturnalia consisted of feasting, drinking, games and general merriment and was celebrated during the Winter Solstice.
The strict social order of Roman society was not only loosened, but partially reversed with the slaves given more freedoms during this time, and their masters often wore the felt hat (pilleus) of the freed slave.
The Saturnalia was the jolliest of all Roman festivals, and it was customary for everyone to greet each other with a hearty 'Io Saturnalia!' The connection with Sol Invictus and the importance of the Temple of Saturn in the Roman Forum will all be discussed in this video!
