There is a cast of it in the Belle Arti at Florence.

The hanging limbs of the Christ have a most pathetic effect, and so has the whole expression of the group.

The effect is obtained by the length of the principal lines.
There is a medallion of the Madonna clasping her dead son at the Albergo dei Poveri, at Genoa, attributed to Michael Angelo; it may have been begun by him during this long period of old age, but it cannot be called his work.

It has been entirely recarved by an imitator.
Michael Angelo made his famous report condemning the design of Antonio da Sangallo for the rebuilding of the Farnese palace upon the shores of the Tiber; it is a mysterious document, in Michael Angelo's own hand, and does not leave Sangallo a single merit.

All the theories are proved by the precepts of Vitruvius.
