  Oh, sword which is very beauty, which has never been dirty or rusty but was always beauty and clear and appropriate in its width and in its length; stronger and firmer than the rest; your hilt is of the whitest ivory, made in the form of the cross, with a very beauty golden handle, and an excellent golden apple of beryl in the end
