Ostara
In England and Germany, this feast probably took place sometime between the spring equinox and the following full moon - the beginning of the summer half of the year. It is named after the goddess Ostara (Anglo-Saxon Eostre), who was so much a part of early English culture that the Christian spring feast, according to the Venerable Bede (a Christian chronicler with no reason to invent Heathen goddesses), took its name from her. Her name is related to the Germanic words for 'east' and 'glory'; she was probably the embodiment of the springtime. She was known only to the Anglo-Saxons and Germans, not the Scandinavians, who called the feast at the beginning of summer 'sigrblót' (victory-blessing). Since there is so much overlap of folk-tradition between this feast and the May Day festivities, it is quite possible that May Day could have been the summer-feast in the colder Scandinavian climate.
Heathen folk customs associated especially with Ostara's feast include the painting and hunting of Easter eggs, which, according to German tradition, were brought or laid by the 'Easter Hare' (the earliest form of the slightly diminished American 'Easter Bunny'). Diana Paxson suggests that the Hare was the holy beast of Ostara, slain and eaten only at her blessing; in Germany, bakeries sell hare-shaped cakes at this time of year. Fires were also kindled on the hilltops at dawn, especially in Germany.
Another common folk-custom which still survives in rural areas is the performance of plays at which Summer battles with Winter and drives him out, or at which an effigy embodying Winter is beaten, burned, or drowned.
Today, Ostara is seen as the feast of awakening - for the Earth, the gods and goddesses, and the human soul. Life becomes brighter and more joyful after the Ostara feast has been rightly held.
