Urizen

Urizen the Architect was the name the Eremites gave to the first President of the Great Houses. In Eremite art, they portrayed him as a blind old man using a set of dividers to measure his own dung as spittle hung from his lips. Despite their vows of silence, the Eremites celebrated the "rites of Urizen" by laughing freely. (PROSE: The Book of the War)
