Angling.
The father of angling, Izaak Walton (15931683). Angling is called the gentle craft; shoemaking was also so called. Probably there is a pun concealed in the first of these; a common bait of anglers being a gentle. In the second case, St. Crispin was a Roman gentleman of high birth, and his craftsmen took from him their title of gentle (genersi).
