‘The tradition of visually representing madness in the form of various icons, whether physiognomy, or body type, gesture or dress, points towards the need of a society to identify the mad absolutely. Society, which defines itself as sane, must be able to localize and confine the mad, if only visually, in order to create a separation between the sane and the insane.’
