Ptolemy, Tacitus and the tribes of north Britain

Abstract

Ptolemy's list of places in north Britain, arranged by tribe, may include both native sites and Roman forts. Unallocated fort names may have been added by Ptolemy to the list of what he thought was the appropriate tribe, possibly not always correctly. Separation of the two groups of names allows a re-allocation of territories to be attempted. Au (abr A R)
