But my favorite front runner was mentioned by The Venerable Bede, a Christian scholar (672-735 CE) when he recorded that Easter was named after Eostre (a.k.a. Eastre). She was the Great Mother Goddess of the Saxon people in Northern Europe. Her name was derived from the ancient word for spring: "eastre."
It didn't hurt any that there was already a pagan celebration predating Christianity by 200 years, about Cybele, the Phrygian fertility goddess, and her fictional consort Attis, who was believed to have died and been resurrected each year during the month of March.
Attis (who was the re-constituted Osiris, Dionysus, or Orpheus with a new name) was a god of plants, particularily perennials. Born of a virgin, he died and was reborn annually. The festival began on Black Friday and culminated after three days in a day of rejoicing over the resurrection.
