A remarkable window-top from the 15th century
which was in typical Irish fashion originally interpreted as a mason's hammer
!
Carvings of disembodied male genitals feature on the corbels of some churches
in the West of France
and NW Spain.
The motif on the right might be a spider's web, symbolising the snares of sin.

Compare with an end-stop carving on a window of Colsterworth church in Lincolnshire.
