Raphael Custos - engraver

[Paul Ferguson]

"Featuring four alchemical engravings by Raphael Custos — much reproduced since Carl Jung included the third as “The Mountain of the Adepts” in Psychology and Alchemy (1968) — Cabala’s leading symbol is the looking glass, which the author offers as a tool for penetrating the mysteries of alchemy and divinity."
