Ivory Hunting horn now at Greystoke Castle
about two feet in length, bought at Roterdam [sic] 1830, which came from Germany, this from the style of its workmanship (which is in slight relief) I conceive to be as early a date as the horn at Aix la Chapelle, and that given to Orlando at Toulouse. There is a spirited representation of a Dog hunting the Ibex, this is repeated on both sides of the horn, and the other part represents a hunter spearing a Stag.
