he Known translations of Old English Bible translations (pre 1066)
Aldhelm (b. 639 d. 25 May 709) is thought to have written an Old English translation of the Psalms, although this is disputed.
Caedmon is mentioned by Bede as one who sang poems in Old English based on the Bible stories, but he was not involved in translation per se.
A translation of the Gospel of John into Old English by the Venerable Bede, which he is said to have prepared shortly before his death around the year 735. This translation is lost; we know of its existence from Cuthbert's account of Bede's death. 
The Vespasian Psalter , an interlinear gloss found in a manuscript of the Book of Psalms. The gloss was prepared around 850. This gloss is in the Mercian dialect.
Eleven other 9th century glosses of the Psalms are known including Eadwine's Canterbury Psalter 
King Alfred had a number of passages of the Bible circulated in the vernacular in around 900. These included passages from the Ten Commandments and the Pentateuch, which he prefixed to a code of laws he promulgated around this time. Alfred is also said to have directed the Book of Psalms to have been translated into Old English. Many scholars believe that the fifty Psalms in Old English that are found in the Paris Psalter  represent Alfred's translation.
Between 950 and 970, Aldred added a gloss in the Northumbrian dialect of Old English (the Northumbrian Gloss on the Gospels) to the Lindisfarne Gospels as well as a forward describing who wrote and decorated it.

At around the same time, a priest named Farman wrote a gloss on the Gospel of Matthew that is preserved in a manuscript called the Rushworth Gospels. 
In approximately 990, a full and freestanding version of the four Gospels in idiomatic Old English appeared, in the West Saxon dialect; these are known as the Wessex Gospels. Seven manuscript copies of this translation have survived; they apparently had some currency. This version gives the most familiar Old English version of Matthew 6:9–13, the Lord's Prayer:
Fæder ure þu þe eart on heofonum, si þin nama gehalgod. To becume þin rice, gewurþe ðin willa, on eorðan swa swa on heofonum. Urne gedæghwamlican hlaf syle us todæg, and forgyf us ure gyltas, swa swa we forgyfað urum gyltendum. And ne gelæd þu us on costnunge, ac alys us of yfele. Soþlice.
At about the same time as the Wessex Gospels, a priest of Dorsetshire named Ælfric produced an independent translation of the Pentateuch with Joshua and Judges.
The Caedmon manuscript which was initially ascribed to Caedmon, was written between 700-1000. The extant manuscript was copied about 1000. It includes Biblical material in vernacular verses.
In 1066, the Norman Conquest marked the beginning of the end of the Old English language and initiated profound changes in its vocabulary. The project of translating the Bible into Old English gradually ended after that process began. We then enter the period of change from Old English to Middle English, with concurrent efforts for Bible translations in that language.
