Compare the theriomorph above left with the dolphin on this Pictish pillar at

Garioch (Aberdeenshire)

The comb and the mirror underneath the dolphin are symbols of vanity and luxury also attached to mermaids.

Compare the theriomorph above also with (threatening ?) figures on a 10th century Irish cross at
Castledermot,

and with a theriomorph threatening Eve who is covering her 'pudenda' on a doorway at Barret (Charente)
