mathematical-impressionsSince the 1970s, Fomenko has produced more than 280 illustrations, 84 of which — 61 black-and-white and 23 color — are collected in this remarkable anthology. Alongside the images are Fomenko’s original captions, illuminating both the inspiration for the artwork and the historical subtexts for it.

Thanks to the people at Good Morning Silicon Valley for pointing this one out.
