Gildas (xxiii,) so calls him.
"The groans of the Britons" are said by Bede to have been forwarded to Aetius "thrice Consul," i.e. in 446, on the eve of the great struggle with Attila.
Nennius (xxviii.) so calls them, and they are commonly supposed to have been clinker-built like the later Viking ships. But Sidonius Apollinaris (455) speaks of them as a kind of coracle. See p. 37.
"Quin et Armorici piratam Saxona tractus
Sperabant, cui pelle salum sulcare Britannum
Ludus, et assuto glaucum mare findere lembo."
('Carm.' vii. 86.)
