Yates does an admirable job of researching this art. She begins, as many before her, with the tale of Simonides and his invention of the loci method of mnemonics. She also captures the scope and breadth of an art which traditionally formed part of the liberal studies of any educated westerner, be he Greek, Roman, or German. Yates leads the book towards a more occult vein when she studies Bruno and some of the medieval contributors to this practice. In the book's most interesting moments, she suggests that the Renaissance thinkers' search through the ancient memory treatises directly led to the search for method that Descartes, Bacon, et al. ruminated upon to create the modern foundations of science. Though this is a well-researched, and at times interesting book, the read goes slowly. Many of the themes and ideas appear in an overly repetitive fashion. Further, it is not a 'how to' book but a book on the history of an idea; one will know little about the improvement of memory and all the claims of the ages appear to be tricks at best. The spectacular memories of a few individuals seem less associated with a method and more a function of physiology. Whether or not this ars memoria should be reinstated seems questionable even after this long essay. Worth a read if you have the time and interest; can lead one on a thought-provoking journey with patient reflection.
