File:Roman 'tutulus' disc brooch (FindID 574188).jpg

English: A damaged and incomplete copper-alloy 2nd-century Roman disc brooch of the tutulus type. The circular brooch would have originally had eight plain, squared off peripheral lugs; three are now missing. The lugs are external on a rim. The rim is echoed by a ridge within; the groove within may have held enamel. This border has received considerable old damage leading to fractures and losses at the circumference and the grooved zone within. A second zone of similar width sits within the inner ridge and before the central boss; this has suffered considerable losses and abrasions too. The central boss rises to a central flared button with pellet centre; the area around may have held enamel. On side of the button has been bent upwards. There is also a perforation to one side of the cone of the boss. The edge of the boss has a ropework border with wireline within. On the lower surface is a concavity corresponding with the cone. Outside this, at the circumference, is a double D-shaped double lug, perforated to take a hinged pin, now missing. At the opposite side, also aligned with a lug, is the sub-triangular catch-plate. The brooch has a orange/brown colour. A tutulus brooch with eight circumferential lugs, though less elaborate, can be found illustrated in Hattatt (2000, 347; ref. 1431).
