Los Demiurgos

Cracking along on his feet, tapping shells and sand with his cane, Stephen thinks, "Sounds solid: made by the mallet of Los Demiurgos. Am I walking into eternity along Sandymount strand?" The eternal principles here are supplied by William Blake, who conceived of "Los, the creator" as the earthly form of one of the Four Zoas (the primal faculties), and by Plato, who conceived of a δημιουργός (demiourgos) or "creator" that fashioned the visible world. Stephen's idea of "walking into eternity" was probably directly inspired by reading Blake.
