Fuller: The word "full" is from the Anglo-Saxon fullian, meaning "to whiten."
To full is to press or scour cloth in a mill. This art is one of
great antiquity. Mention is made of "fuller's soap"
(Malachi 3:2) and of
"the fuller's field"
(2 Kings 18:17) At his transfiguration our Lord's
rainment is said to have been white "so as no fuller on earth could
white them"
(Mark 9:3) En-rogel (q.v.), meaning literally
"foot-fountain," has been interpreted as the "fuller's fountain,"
because there the fullers trod the cloth with their feet.
