To memorize anything, distribute vivid, emotionally stirring imagined images around a piece of familiar architecture. This is the method of loci, or memory palace method, first developed in classical antiquity.
Giordano Bruno perfected the art in the late 16th Century. He published a series of books on the subject, beginning with De Umbris Idearum (On the Shadows of Ideas). His work and life would lead him across the major centers of Renaissance Europe, to the patronage of kings and nobles, the scorn and envy of academics, and ultimately to his imprisonment and execution at the hands of the Roman Inquisition in 1600.
Bruno’s works have been reprinted periodically since his death. The current edition is the first complete English translation to be published.
