This is a catalogue of the rather nice collection of gems in the Royal Albert Memorial Museum, Exeter, consisting almost entirely of the bequests of Lt. Col. L. A. D. Montague in 1946 and of Dr N. L. Corkill in 1966. Together they document the history of seal engraving from 3000 BC to the nineteenth century, from the Near East, Greece and Rome, and the Renaissance, from Akkadian cylinder seals to Sassanian stamp seals and Bactrian ringstones.
