The "Marlborough gem" is a carved onyxcameo that depicts an initiation ceremony of Psyche and Eros. It is the most famous engraved gem in the extensive and prominent collection both inherited and expanded by George Spencer, 4th Duke of Marlborough. It is conserved in the Boston Museum of Fine Arts, where it is called Cameo with the Wedding of Cupid and Psyche, or an initiation rite, reflecting the view of its subject generally held until the last century. In the carving, Cupid and Psyche are depicted as veiled putti accompanied by other infants, one of whom holds over their heads a winnowing-fan filled with pomegranates, emblems of bios and fertility. Signed Tryphon, it was probably made in the 1st century AD, though its date has been questioned and a case made for a 16th-century origin. The Gem was given by Peter Paul Rubens, who declared that he loved gems beyond all other relics of antiquity, to Thomas Howard, 21st Earl of Arundel, in the 17th century. Another famous gem from the Marlborough Collection that is also sometimes known just as the "Marlborough Gem" is a head of Antinous. The artist's signature is minutely incised into the black background of the stone, just above the central figures in the frieze-like procession. Various 18th-century sources reported that Louis XIV of France had been prepared to offer the equivalent of £4000 in the previous century. An early 16th-century drawing of the subject by the architect and antiquarianPirro Ligorio was seen among the papers of Rascas de Bagarris recorded by Jacob Spon. The gem was carefully drawn by Theodorus Netscher and engraved by Bernard Picart for Philipp von Stosch's Gemmae antiquae caelatae which placed its magnified image in the hands of all Europe's antiquarians and rendered it part of the visual repertory of milordi on the Grand Tour, who knew it from its illustration added to the 1728 French edition of the Jonathan Richardsons' Account..., published in French as Traité de la Peinture et de la Sculpture... Amsterdam, 1728; in the 18th century the English could be counted on to pay top prices for outstanding carved hardstones of assured antiquity. Once in the Marlborough collection, the gem was often redrawn: Giovanni Battista Cipriani painted a version of the gem, Francesco Bartolozzi engraved it, James Tassie cast it in opaque coloured glass paste, and for Josiah Wedgwood, first William Hackwood reproduced a low relief from Tassie's cast, and then John Flaxman modeled it at a larger scale; both versions were executed in Wedgwood & Bentley's white-on-blue jasperware that imitated cameos; the 'Marlborough Gem' first appeared in Wedgwood's 1779 catalogue. The Wedgwood plaque, available in several sizes, appears mounted on Parisian and London furniture, and a marble relief of the scene is set in the chimneypiece of the red drawing room at the original home of the Marlborough gems. It became so familiar that the caricaturist James Gillray engraved a parody of it in 1797, lampooning the long-delayed marriage of Lord Derby to the actressElizabeth Farren, who is travestied as a tall, lanky veiled figure, who is offered a countess's coronet instead of the winnowing fan of pomegranates, with the plump cherubic Lord Derby at her side. By 1870 the Marlborough collection cataloguer observed, "the design has been reproduced in all sorts and materials of art, perhaps oftener than any other similar subject." The 7th Duke of Marlborough sold the gem, catalogued as "The Marriage of Cupid and Psyche", together with the other Marlborough Gems, at Christie Manson & Wood, London, in 1875. The collection, sold in a single lot that brought £35,000, went to David Bromilow of Bitteswell Hall, Leicestershire, who maintained the collection intact; when his daughter subsequently sold the Marlborough gem with the rest of the Bromilow Marlborough hardstones by Christie's, 26–29 July 1899, the cameo was sold for £2000. Now the collection is very widely dispersed, with large numbers in American museums. Pictures of impressions, electrotypes and many originals are now published on-line by the Beazley Archive.
