The frame surrounding Murillo’s Immaculate Conception is most likely English, made during the ownership of the painting by Sir Sampson Gideon (1745-1824). The painting is recorded in his collection in 1759.
It reflects British Rococo stylistically and the very elaborate form of the carving is enhanced by the as-symmetry notable in passages of ornament, principally in the centre top and bottom. The frame has been regilded at least once and perhaps now lacks some of the subtle articulation of surface it might once have carried.
The four sections of the frame are intended to be taken apart for travel. The corners are held together with tie-bolts, located horizontally, the corner joints being square cut on the face rather than mitred.
A number of designers and makers could be the source of this frame.
Thomas Johnson (active c.1755-63). Matthias Lock (active c.1740-70). Henry Copland (active 1746-66). John Linnell (1729-96).
The frame is one of a number of interesting frames in the collection which are stylistically out of sequence with the paintings they surround. Notable other examples are the frames on Poussin, The Crossing of the Red Sea (1843-4), van Dyck Countess of Southhampton (1246-3) and Ribera, The Martyrdom of St Lawrence (2006.390) , all paintings from the seventeenth century with frames from later periods.
