These are notes from Martin Kemp, 'The mark of truth: Looking and learning in some anatomical illustrations from the Renaissance and eighteenth century' in WF Byrum and R Porter, eds., Medicine and the Five Senses (Cambridge, 1993) pp85-121
Notes for the seminar on 29 Jan 2013. They may not be strictly coherent but offer a summary of Kemp.
