Final answer:
Bede's eighth-century text, the Lindisfarne Gospels, was not written in Old English, but it does contain a vernacular translation in English.
Step-by-step explanation:
No, Bede's eighth-century text was not written in Old English. The manuscript, known as the Lindisfarne Gospels, was created by Eadfrith, a bishop of Lindisfarne, and it is written in Latin. However, it is important to note that a vernacular translation was added between the lines of the Latin text, making it the earliest known Gospels written in a form of English.
