Annotation:[Canterbury Catalog: Cornelian with agate banding. Oval flat. Head of an Emperor, possibly Titus. Also with a cast of the image (b). Cornelian is a red variety of chalcedony, which is cryptocrystalline quartz. Its red colour is due to the presence of iron impurities in the form of iron oxide or hematite. It can vary from a flesh red to a clear red. It is usually cut en cabochon, or into beads, and is also used for intaglios and cameos. Imitations of cornelian are made by the staining of agate. Cornelian is related to amethyst and citrine. Titus Flavius Vespasianus, commonly known as Titus (December 30, 39AD September 13, 81AD), was a Roman Emperor who briefly reigned from 79AD until his death in 81AD. Titus was the second emperor of the Flavian dynasty, which ruled the Roman Empire between 69AD and 96AD.] (approx 79-81AD)
