that of the Greeks, among whom pederasty was a socially acknowledged relationship between freeborn males of equal social status. Roman men, however, were free to engage in same-sex relations without a perceived loss of masculinity only as long as they took the penetrative role and their partner was a social inferior such as a slave or male prostitute: the paradigm of "correct" male sexuality was one of conquest and domination. There are significant differences to pederastic scenes found on classical Greek vases. The sex act is presented in graphic detail, and the "beardless youth" appears to encourage the penetration, grasping his lover's arm. In Roman artwork there is an assumption that the penetrated youth is a slave or prostitute and on the Warren Cup, a mutual tenderness is represented. Both scenes show draped textiles in the background, as well as a cithara (appearing as an eleven-stringed lyre, often symbolic of pleasure and drinking parties) in the former scene and tibiae (reeded pipes) with finger holes being depicted in the latter. These, along with the careful delineation of ages and status and the wreaths worn by the youths, all suggest a cultured, elite, Hellenized setting with music and entertainment. The active partners in the two sexual depictions are wearing leaf crowns, likely to be symbolically made from myrtle. Myrtle is an evergreen shrub, grown in the Roman period for medical and ritual purposes, such as weddings, and dedicated to Venus, the Roman goddess of sexuality and love. It has a smaller leaf than the more commonly depicted laurel. Myrtle was used to create the corona ovalis, a military crown awarded as an ovation but a far lesser award than the insignis corona triumphalis, one interpretation of the use of myrtle crowns on the Warren Cup, being a visual pun of homosexual penetration as an easy victory. Modern provenance Warren purchased the cup in Rome from a dealer in 1911 for £2,000. It was bought in Jerusalem and said to have been found near the city in Battir (ancient Betar), with coins of the emperor Claudius, possibly buried during the upheavals of the Jewish Revolt. The cup became a prized item in Warren's large art collection, referring to it with friends as the "Holy Grail". The first publication featuring the cup was in 1921, when Gaston Vorberg published a volume of 113 plates of erotic artwork from ancient artefacts. The photographs show
