This article argues that despite individual Fellows’ interest in artistic practices, and similarities between a philosophical and a connoisseurial appreciation of art, the Royal Society as an institution may have been wary of image-making as a way of conveying knowledge because of the power of images to stir the passions and sway the intellect.
