The Byzantine scholar Procopius, writing c. 565 in his "Gothic Wars" (Bk IV, Ch 20), said that "Brittia" in his time (a different word from his more usual "Bretannia") was occupied by three peoples: Angles, Frisians and Britons. Procopius said that he was relating information from an informant, likely a member of a Frankish delegation to the court at Byzantium, and did not assert the information as fact. Other information that he related included the assertion that there were no horses in Britain, that Hadrian's Wall separated the temperate parts of the island from the uninhabitable parts, and that 'countless people' had attested that Britain was the home of dead souls. His information about Britain, while occasionally useful, is not considered authoritative.
