1st millennium BC. A limestone cylinder seal with two chasing monsters and various objects in the field; accompanied by a museum-quality impression and typed and signed scholarly note issued by W.G. Lambert, Professor of Assyriology at the University of Birmingham, 1970-1993, which states: 'Cylinder Seal of Chalcedony 29.5 x 13.5 mm. The design shows a frieze of two rushing monsters as if chasing each other: both lions' bodies, but [sic] wings, birds' heads and brush tails. The differences are that one has closed beak and much fur along the underside of the body, while the other has open beak and no such fur. There is a star and a crescent in the sky, and a rhomb and fish are fillers. Below the scene there is a kind of base of lines and globes, part of which is repeated below the monster with closed beak. This is a Neo-Babylonian seal, c.1000-800 B.C. It is fine work of its kind, and save for a chipped edge is in good condition.' 6.68 grams, 28mm (1"). The Signo collection, the property of a West London businessman, formed in the late 1980s-early 1990s; item number W-619; academically researched and catalogued by the late Professor Lambert in the early 1990s; accompanied by an original typed and signed scholarly note by Professor Wilfrid George Lambert.
