Within modern Paganism these days an alternative name for the Spring Equinox is that of Eostre. When I initially underwent my studies in contemporary Wytchcraft back in the 1990s, the only alternative name that I was aware of for the Spring Equinox was the use of the adjective “vernal”. This has since led to research into who or what Eostre is. One of such pages that shed some light about Eostre was, who provided the following information.
The name Eostre is thought to be derived from a goddess of German legend, according to Jakob Grimm in his Deutsche Mythologie. A similar goddess named Eostre was described by the Venerable Bede, an English Benedictine monk of the 7th century. Bede indicated that this name was used in English when the Paschal holiday was introduced. Since then this name (not the holiday) has been converted to Easter, or in German Ostern. Some scholars question both Bede’s and Grimm’s conclusions due to a lack of supporting evidence for this goddess. Others argue that a lack of further documentation is not surprising given that Bede is credited with writing the first substantial history of England (in which he described Eostre as a goddess whose worship had already passed) and Grimm was specifically attempting to capture oral traditions before they might be lost.
