of Roman glass. The Hohen-Sülzen bowl, most valuable of six glasses found in 1869 in two Roman sarcophagi. Except the Dionysos bottle at the Landesmuseum Mainz, all of them are missing since 1945. Historiography There was little discussion of the group until the 1950s. In 1950 Victor, Lord Rothschild asked the British Museum to investigate his Lycurgus Cup, which he subsequently sold to the museum in 1958. In 1956 the German scholar Fritz Fremersdorf published an account of their manufacture by cutting and grinding, which remains the conventional theory. In 1959 a detailed account of the Lycurgus Cup was published by Donald Harden and Jocelyn Toynbee, which also discussed diatreta as a group, effectively for the first time. A major exhibition in 1987, "Glass of the Caesars", organized by the Corning Museum of Glass and shown in the British Museum, Cologne and Milan, united several of the leading examples, and its catalogue, edited by Harden, remains a key work. Modern replica cups have been made several times, partly to test hypotheses of the method. Supposedly an early German example, made in 1906, was filled with a celebratory drink of champagne and then broke at the rim when the cutter began to drink.
