He is usually depicted as a bearded old man; he sometimes bears architect's tools, to create and constrain the universe; or nets, with which he ensnares people in webs of law and conventional culture.
He gets much of his characterization from popular conceptions of Yahweh, the god of the Old Testament. The name may come from "You Reason", i.e., the accepted wisdom of the age; or from the Greek horizein, "to set limits." Not a benevolent character, Urizen oppresses Orc, who embodies revolutionary passion and creativity, and who serves as a suffering saviour figure. He is also an enemy of Luvah, the spirit of love.
