But the engraver, it would seem, thought it a pity that the other portion of such a fine stone should be left unemployed; so he made that into another antique fragment, with another subject; that is to say, the head, neck, and fore-quarter of a lion (118) passant, very well engraved; not a modern heraldic lion passant, but a real grumpy-looking lion, from an arena, perhaps, of the Coliseum—it would pass for the fore-part of the group of Cybele riding on a Lion, which is a common antique subject (119); this fragment he antiquified more than the other; for whereas the one with the sacrifice is smooth on the back, the other with the lion has been much scratched.
