It’s my understanding the scribes/monks ultimately found safe haven in Ireland far away from the destruction of Rome.
Nah. The monks were only in Ireland because of St Patrick, who was sold as a slave in Ireland, Christianity spread into the rest of Britain from Ireland; building monasteries was a response to the local gentry and not long after, the Vikings.
