During this period Europe was ravaged by barbarians like the
Goths, the Vandals and the Huns, who swept down from the east and
north. They destroyed many of the better things that had existed
under the Romans. When they finally settled down, little was left of
the civilization which they had plundered.
The Church invented the monastery as a refuge to preserve
something of the Christian life and culture that there had been
under the later Roman Empire. Reading and writing continued in the
monasteries: in them some of the old authors' books were saved,
studied and copied.
When the churches and monasteries were destroyed in one area, enough survived elsewhere for missionaries to return to a fresh start after the worst was past. In the simple cells of the Irish monks, Greek was still taught after it had been lost over much of Europe.
