While Fthinóporo is a festival invented in the modern age to reflect our Temple's traditions, including our adherance to The Truth of Devotion, the festival also takes inspiration and influence from the Wiccan Sabbat of Mabon.

From Wicca Living, regarding Mabon:

"Mabon falls on the Autumn Equinox and is the second of the three harvest festivals [...] at Mabon the days and nights are of equal length [...] Though temperatures may still be warm during the day, summer has truly come to an end. [...] The days were longer than the nights until this moment, and after this the nights will begin their reign. [...] reminding us that everything is temporary, that no season lasts forever, and that neither dark nor light ever overpowers the other for long."​

Temple Hyacinthus observes Fthinóporo as a celebration of the Autumnal Equinox. Additionally, the festival occurs during the month of Boathoos - during which we honor the duality of Lady Kore and Queen Persephone. It is at midnight on Fthinóporo that we observe the mythic return of Lady Persephone to the underworld, where she will remain until Anoixi (the Vernal Equinox). During Fthinóporo, we encourage incorporating Queen Persephone, Lady Demeter, and King Pluton into your rituals and celebrations.
