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” (Mal. 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, meaning literally “foot-fountain,” has been interpreted as the “fuller’s fountain,” because there the fullers trod the cloth with their feet.
