The Albertina Collection at Vienna yields us an elaborate design for the sacristy, which appears to have been worked up from some of the rougher sketches.

It is executed in pen, shaded with bistre, and belongs to what I have ventured to describe as office work.

It may have been prepared for the inspection of Leo and the Cardinal.

Here we have the sarcophagi in pairs, recumbent figures stretched upon a shallow curve inverted, colossal orders of a bastard Ionic type, a great central niche framing a seated Madonna, two male figures in side niches, suggestive of Giuliano and Lorenzo as they were at last conceived, four allegorical statues, and, to crown the whole structure, candelabra of a peculiar shape, with a central round, supported by two naked genii.

It is difficult, as I have before observed, to be sure how much of the drawings executed in this way can be ascribed with safety to Michelangelo himself.
