The gloriously ornamental frames in the Piccolomini Spannocchi collection
Jacob Simon, Research Fellow at the National Portrait Gallery in London, examines a fascinating and perhaps less well-known collection of 16th-18th century paintings, which has been reassembled after years of dispersal and is now on show again in Siena. One of its notable features is the even more extraordinary group of original and near-contemporary frames in which it is partly housed.
