Item one: for the type, cf. M. Henig, The Lewis Collection of Gemstones, Oxford, 1975, p.65, no. 279; and M. Henig, M. Whiting and D. Scarisbrick, Classical Gems, Ancient and Modern Intaglios and Cameos in the Fitzwilliam Museum, Cambridge, 1994, p.186, no. 408 where it has been suggested that this scene represents a contract, perhaps between two deities. Item three: similar in style to Henig et al., Classical Gems, pp. 426-427, nos. 876-879.
