This impressive wooden model of St Paul's Cathedral, on show at the summer Olympia Fine Art & Antiques Fair, was briefly believed to be by Sir Christopher Wren until the scholarship of Sir William Whitfield proved that it could not be so. Belgian dealer Yannick David obtained the model from a private family in Belgium, and showed the model to the Dean of St Paul's, who called in Whitfield, the masterplanner of Paternoster Square. Whitfield said it could not be Wren's work because it included changes to the west steps introduced in the late eighteenth century, and also that it was not of fine enough quality. The model, which measures about 1m in every direction, is now thought to be the work of a gifted European amateur of the early nineteenth century. The fair will run from 4-14 June.
