Cf. Hattatt, R., Ancient and Romano-British Brooches, Sherborne, 1982, p.147, no.140; for the Hadrian’s coin see Mattingly, Roman Coins from the earliest times to the fall of the Western Empire, London, 1977, pl.XXXIX, 25 (BM inventory no.1672).12.9 grams, 33 mm (1 1/4 in.). From a Cambridgeshire, UK, collection, 1990s. This brooch is an extreme rarity and is believed to be the finest known example.Apanied by an academic report by Dr Raffaele D'Amato. This lot has been checked against the Interpol Database of stolen works of art and is apanied by search certificate number no.11747-202502. These brooches were a mystery until one was excavated at Wiggonholt, Sussex, together with three other damaged specimens now in the Devizes Museum, all from Wiltshire (more precisely Cold Kitchen Hill). The image of the original coin was slightly modified. The local craftsman improved the coin type making his brooch more interesting, transforming the Emperor Hadrian on horseback into two cavalrymen, probably the sacred Dioscuri, while the Roman Aquila, symbol of the legions, was taken from the top of the signa and placed in the foreground.
