A NOTE ON GROTESQUES
It is only relatively recently in human history that people with bodily and facial disfigurements have disappeared from view.
First, they were 
    kept off the streets, confined either to what amounted to house-arrest, or 
    placed in prisons
    known simply as 'institutions'.
More recently, plastic surgery has eliminated much malformation.
Although exhibitionists 
    are mostly grotesque in their bodies, not many have grotesque faces. 
    This became a feature of 'Gothic' sculpture - especially of gargoyles, bench-ends 
    and misericords
    - and may indeed have contributed to the coining of the very word 'Gothic'.
Recently, I came 
    across, on a gay contact site, 
    an example of a malformation or disfigurement
    which would not look out of place on any mediæval church.

If this apparently-blind 
    man did indeed post his own picture on that site, he deserves to be congratulated,
    because nowadays, in the Anglophone world at least, mothers would abuse him 
    for daring to walk abroad
    and frightening their precious, hideously-overprotected children.
