This figure resides on St. Michaels church Laxton, Nottinghamshire. It combines the exhibitionist motif with the devoured sinner.
Sr Michaels in Laxton dates back to the 12th century with the nave and the pillars being given a date of around 1190. The figure above however does not date to this period. It consists of a hellish monster devouring a man with only the legs buttocks and genitals being visible. This motif can be seen elsewhere in the UK two examples on this site can be found at Devizes with only the legs and shooed feet visible and a female example at Alstonefield in Derbyshire. Both of these examples date from the 12th century unlike this figure.
