The German furniture-maker was Rome’s leading cabinet maker during the 1660s and 1670s and worked for successive Popes and a number of leading Italian families after settling in Rome in 1655 where he entered the papal service.
Arts Minister Michael Ellis said “documented works of significance from this period are very rare and this ebony veneered cabinet is one of four created in Herman’s workshop between 1669 and 1678”.
One of the cabinets sold at Sotheby’s in December 2007 for a premium-inclusive £1.08m.
The cabinet is valued at £3.3m and the government is hoping a UK buyer will come forward by July 8, 2019. This date could be extended until November 8 if a buyer with a serious intention to raise funds comes forward.
The government issued the export bar to the owner of the cabinet following a recommendation from the Reviewing Committee on the Export of Works of Art and Objects of Cultural Interest (RCEWA) which made its decision on the grounds of its “outstanding significance to the study of Baroque decorative art and cultural history”.
RCEWA committee member Christopher Rowell said: “The cabinet has been recently reunited with its original cresting: a reduced gilt bronze copy of the Antique bronze equestrian statue of the Emperor Constantine, which Michelangelo placed in the centre of his Piazza di Campidoglio, Rome.
“This is the only one of the set of four cabinets to have been acquired for an English collection. Indeed, this remarkable composite work of art may well have been in England since 1738, when a very similar cabinet was seen by the antiquary George Vertue at Cowdray House, Sussex. It is very much to be hoped that the funds will be raised for it to remain in this country.”
Veneered with lapis lazuli, a blue semi-precious stone, and jasper gemstones and mounted in gilt bronze, the cabinet includes 14 gouache miniature paintings depicting Roman basilicas and the city-wide processions that took place following the coronation of a new Pope.
The cabinet also features a clock by Giovanni Wenderlino Hessler and a virginal by Giovanni Battista Maberiani. It is supported by an elaborate carved giltwood table formed of two male figures, masks and scrollwork.
The other cabinets making up this series of works are now housed at the Chapel of the Virgin of Loretto in Krakow, Poland, and at Rosenborg Castle and Fredensborg Castle, both in Denmark.
