Latin Europe’s low point came soon after 900 when, within the space of a couple of years, areas of central France were ravaged in quick succession by pagan Vikings from the north, Muslim Moors from the south, and pagan Magyars from the east: Christians had nowhere left to hide. Perhaps history would ultimately write off the Christian venture into western Europe as rash overreach, a diversion from Christianity’s natural destiny, which evidently lay in Asia. Europe might have been a continent too far.
