In the centre of the triptych, the Virgin sits on a throne of Flemish
renaissance design. On the right, St. Ambrose; on the left, St. Louis
of Toulouse. The royal rank of the latter Saint (nephew of St. Louis,
King of France, and son of Charles of Anjou, King of Naples), who
renounced his succession and became Bishop of Toulouse, is commonly
indicated as here, by fleur-de-lys upon a blue ground.
