Description:
Stranded whales were, of course, very important in medieval times. In July, 1295, for example, there is on record the pleadings of a case in County Kerry in which Robert de Clohulle was charged with having appropriated a whale to his own use "in prejudice of the Crown" (Cal. Just. Rolls Ire., 1295-1303, pp 29, 54-5).
