Historia ecclesiastica gentis Anglorum
The Venerable Bede wrote in his "Historia ecclesiastica gentis Anglorum" of a well near Golborne sacred to St. Oswald's memory. This well had been suggested as the site where Penda, the pagan king of Mercia, slew the Christian King Oswald, later St Oswald, in the Battle of Maserfield, in 642. It is more generally accepted though that the site of that battle was some considerable distance to the southwest, near Oswestry.
