Design for an Altar, Brush and gray wash, pen and gray ink, black chalk on paper, The left half of an architectural design for an altar is shown. The mensa had a convex plan, with four steps in front of the straight central part. The head piece has four steps. The retable consists of a high and complicated pedestal, with the figure of the Virgin praying in front of the Cross. The wall behind the retable had the form of a niche. At its front corner an angel is kneeling upon a pedestal, carrying a candlestick with five arms upon his head. At the corner of the mensa stands a candelabrum with two flying angels beside its shaft, and with a standing angel carrying three candle branches upon the head. The stucco decoration of the wall is suggested but not entirely executed., Italy, 1700-57, architecture, Drawing, Drawing
