LUPERCALIA: (February 15th) celebration of bodily autonomy, sexual liberation, and reproduction. Based on the Roman festival of the same name, Lupercalia falls on February 15. In keeping with the ancient tradition, February 13th and 14th are observed as feast days leading up to the actual holiday. What we are translating this to in TST is a "hail yourself" day. This idea offers a parallel to the "others-centered" traditions of Sol Invictus.

A centerpiece of our religious movement and icon of modern Satanism, the Baphomet with Children statue was commissioned by The Satanic Temple in 2014 and created by Mark Porter with "respect for diversity and religious minorities" in mind. On July 25, 2015, The Satanic Temple unveiled Baphomet to a large crowd of devotees in Detroit, signaling the beginning of the new Satanic era. We observe this milestone in Satanic history by celebrating Unveiling Day.
