Crockets
Crockets, derived from the idea of hook, and also connected with the idea of a lock of hair, are in architecture ornaments often to be found on gables, pinnacles, and the like, where they sometimes take the form of recurved leaves, with sometimes additional ornament. They are also used as ornaments upon the convex part of the crook of a pastoral staff.
