The author presents evidence from three ancient Devon church buildings to support his proposition that their Norman architects and builders used the same Norse measurements that are to be found in present day Russia, namely the 'sajena' of seven feet, and the third part of the sajena (28"), known in Russia as an 'arschine'. As well as touching on the history of these medieval Devon edifices, Watkin provides the names of the Devonians and others associated with their earliest years.
