Portrait of Sir Jonathan Trelawny, successively Bishop of Bristol, Exeter and Winchester Sir Godfrey Kneller (1646-1723)

The picture has something of this: people, portrait, wear, outerwear, veil, royalty, wig, queen, jacket, man, cape, woman, Renaissance, outfit, sash.
Perhaps it’s a portrait of a man with white hair wearing a purple and white robe and holding a cane in his right hand and sitting in a wooden chair.
