This print shows the “brain of someone described as an idiot”. Published in the Journal of Mental Science, the illustration is by George Edward Shuttleworth, who was Superintendent of the Royal Albert Asylum in Lancaster, U. K., between the years 1870-1893.
Shuttleworth’s drawing comes from a huge database of images released recently by the Wellcome Trust Library under a Creative Commons Licence. The database contains old and new images depicting 2,000 years of medical history and human culture.
