From an important Dutch collection; acquired in the early 1990s from Geert Nyboer, Bedum, Netherlands, who acquired the brooch in Northern Holland in the 1970s; this lot has been checked against the Interpol Database of stolen works of art and is accompanied by AIAD certificate number no.10941-181636. This is an extremely rare example of a trefoil brooch with high-relief modelling to the surface detail. The Borre Style decoration was executed with precision in wax and the brooch itself cast by a master craftsman by the cire perdue process, then gilded to capture the glittering effect of the fine surface detailing; a true masterpiece. The trefoil type is based on a three-armed strap distributor for a sword-belt used by the Carolingian Franks, copied and re-modelled to Scandinavian taste and finally re-purposed as a female dress-ornament or brooch. A similar example from Tranby, Denmark, is held by the British Museum under acquisition number 1873,1211.1. The Tranby brooch is however less well-defined in its modelling and appears 'flatter' than the present example.
