The term 'Australian Sort of Roman Revelry' refers to the celebration of SATURNALIA, a festival in ancient Rome that was held in honor of the god Saturn. This festival was celebrated with feasting, gift-giving, and general merrymaking. It was also a time of role reversal, where slaves were allowed to act as masters and masters were expected to serve their slaves. The festival was eventually adopted by many other cultures, including Australia, where it is still celebrated today.
