This mirror is one of a set; three are known but the back of this one is incised IIIII which suggests that the set was longer. The seraphim mask and the apparent length of the set suggests that they may have originally been in a church.
This mirror has been in two of the most distinguished collections formed this century. Percival Griffiths was of the first generation of collectors and part of his collection was dispersed in these Rooms in 1939. J.S. Sykes was of the next generation of collectors; like Lord Plender and Geoffrey Blackwell he was advised by the prolific author and furniture-historian Robert Wemyss Symonds (d.1958)
