Ostara:


Ostara

Names: Proto-Germanic: *Austrôn ("Eastern One")
Western Germanic: Easter (English), Eostra (Anglo-Saxon), Eostre (Anglo-Saxon), Ooster (Dutch), Ostara, Oster (German)
Goddess of: Spring, Rebirth, Fertility, Rabbits, Chickens, Earth
Appearance: Ostara was seen as a wise Earthmother who granted fertility

Not much is known about Ostara, she is the incarnation of spring and rebirth after a cold winter and it is certain that she is an earthgoddess who is concerned with fertility, because of this there is a big chance that she is a member of the Wanen family though even this can not be said with certainty.
The name Ostara was only known to the western Germans though it is believed to have been a title for another (more commonly known) goddess, there are some implications that Ostara is another name for Idunna or Freya though considering her characteristics she was probably Erda/Holda/Berchta/Frigg/etc; the common Germanic earthgoddess.
Although little is known about Ostara she was of big importance to the western Germans; the spring festival Easter, one of the most important holidays of the year, was even dedicated to her as well as the month April.
The Indo-Europeans (and probably the Germans too) always prayed while facing eastwards, because that is where the sun comes up, so the name Ostara ("Eastern One") may be a kenning for a goddess who was worshipped in this way.
