St Mary Redcliffe, Bristol (Avon)

Three column-swallowers photographed by Kjartan Hauglid.
The first is feline, but the other two have a very human appearance.

Can this motif be related to the beast (somewhere between a bear and a dog) in an Ouroboros-position of auto-fellatio,
at Mauriac (Cantal) ?
