The meaning of this name is unknown. It could be derived from the Celtic elements
artos "bear" combined with
viros "man" or
rigos "king". Alternatively it could be related to an obscure Roman family name
Artorius. Arthur is the name of the central character in Arthurian legend, a 6th-century king of the Britons who resisted Saxon invaders. He may or may not have been a real person. He first appears in Welsh poems and chronicles (some possibly as early as the 7th century) but his character was not developed until the chronicles of the 12th-century Geoffrey of Monmouth.
