EXGPIANATION: Oran aves aye 
Shell-mound of Purpura lapillus L., at the pre-historic 
settlements at Portnafeadog (Dog’s Bay), near Roundstone, 
Connemara, all broken by means of rude stone hammers, it 
is supposed, in order to obtain the body of the animal for the 
production of a purple dye, highly prized by the ancient Irish.
