Lewis
Lewis of Clynfyw
Crest: a nag’s head couped, bridled proper. Motto: Be wise as a serpent, harmless as a dove.
A bridled horse in its natural colours. The Lewis shield behind it is red, with three silver serpents knotted in a triangle inside a gold border.
As recorded in Burke’s General Armory for Lewis of Clynfiew. The seal shows the horse with more of its body than Burke’s “head” describes.
