Ar`thur, a British prince of wide-spread fame, who is supposed to have lived at the time of the Saxon invasion in the 6th century, whose exploits and those of his court have given birth to the tradition of the Round Table, to the rendering of which Tennyson devoted so much of his genius.

ARTHUR, KING ARTHUR, A game used at sea, when near
the line, or in a hot latitude. It is performed thus: A man
who is to represent king Arthur, ridiculously dressed,
having a large wig made out of oakum, or some old swabs, is
seated on the side, or over a large vessel of water. Every
person in his turn is to be ceremoniously introduced to
him, and to pour a bucket of water over him, crying,
hail, king Arthur! if during this ceremony the person
introduced laughs or smiles (to which his majesty endeavours
to excite him, by all sorts of ridiculous gesticulations), he
changes place with, and then becomes, king Arthur, till
relieved by some brother tar, who has as little command
over his muscles as himself.
