Arthuis (Welsh, Arthwys/Latin, Artorius/English, Arthur), King
of thePennines. Arthuis succeeded his father, Mor, in the
southern area of hisKingdom: the Pennine region of today. He
was probably a contemporary ofthe great High-King Arthur of
romantic legend, and stories of thelatter's exploits in the
north may well be a muddled memory of thisNorthern King, who is
thought to have fought against the Picts onnumerous occasions.
