 The interior of the room has other signs of wealth; the brass chandelier is large and elaborate by contemporary standards, and would have been very expensive.It would probably have had a mechanism with pulley and chains above, to lower it for managing the candles (possibly omitted from the painting for lack of room).The convex mirror at the back, in a wooden frame with scenes of The Passion painted behind glass, is shown larger than such mirrors could actually be made at this date – another discreet departure from realism by van Eyck.
