Easter, otherwise known as the week long Roman festivities for The Great Mother Goddess Cybele and her consort/child Attis.
Attis who died after self castrating and was after severals days ressurected as an eternal beauty / woman. The festivities were the roman spring equinox, with Attis's own death to symbolize the death of fruits in winter to only reappear in spring.
A pine tree would be felled and taken and erected in front of the Temple of Cybele with its branches decorated with wreaths of violets.
The ceremonies proper would begin Starting with the Dies Sanguinius -
:blood: The Day of Blood :blood: where many followers of the religion, the Galli would flagellate themselves until they bled and some self castrating in order to join their ranks - and become women-like in honour of Attis.
Then the Dies Hilaria - The Day of Joy to celebrate the ressurection of Attis - an act of kindness from Cybele (Gaia/Mother Earth)
Then a day of rest, then a day of washing, and finally a procession and ceremony at the Vatican Sanctuary.
