Although the inhabitants of York were at least nominally Christian
from the mid 9th century, they appear to have continued to hedge
their bets, mingling Christian and pagan beliefs. This is illustrated
well by the use of both Thors hammer and the symbol of the
cross on a rare die for minting St Peters pennies found at
Coppergate. The Viking period saw the beginning of the parish system
and a number of churches are known to have existed at this early
date. A 10th century stone grave marker, carved with animal design
and found at Coppergate, may have come from All Saints church nearby.
