The very elaborate decoration of the Spanish Chapel is fully described in C. &. C. (Hutton) Vol. I., pp. 309–312. There are useful literary illustrations in Venturi, Storia dell’ arte italiana, Vol. V., pp. 792–809. Ruskin in Mornings in Florence gives a partial analysis which is fascinating from a literary point of view, but badly overestimates the merit of the work.
