"Ēostre or Ostara is a Germanic divinity who, by way of the Germanic month bearing her name is the namesake of the festival of Easter. Ēostre is attested solely by Bede in his 8th-century work The Reckoning of Time, where Bede states that during Ēosturmōnaþ (the equivalent of April), pagan Anglo-Saxons had held feasts in Eostre's honor, but that this tradition had died out by his time, replaced by the Christian Paschal month, a celebration of the resurrection of Jesus.
By way of linguistic reconstruction, the matter of a goddess called *Austrō in the Proto-Germanic language has been examined in detail since the foundation of Germanic philology in the 19th century by scholar Jacob Grimm and others. As the Germanic languages descend from Proto-Indo-European (PIE), historical linguists have traced the name to a Proto-Indo-European goddess of the dawn *H₂ewsṓs (→ *Ausṓs),...*aus-, meaning 'to shine' (modern English east also derives from this root)." wikipedia

If thy brother, the son of thy mother, or thy son,
or thy daughter, or the wife of thy bosom,
or thy friend, which is as thine own soul,
entice thee secretly, saying,
Let us go and serve other gods,
which thou hast not known,
thou, nor thy fathers;
Namely, of the gods of the people which are round about you,
nigh unto thee, or far off from thee,
from the one end of the earth even unto the other end of the earth;
Thou shalt not consent unto him, nor hearken unto him;
Deuteronomy 13:6-8
