[5] This final sculpture revisited the theme of the Virgin Mary mourning over the emaciated body of the dead Christ, which he had first explored in his Pietà of 1499.
Like his late series of drawings of the Crucifixion and the sculpture of the Deposition of Christ intended for his own tomb, it was produced at a time when Michelangelo's sense of his own mortality was growing.
In his dying days, Michelangelo hacked at the marble block until only the dismembered right arm of Christ survived from the sculpture as originally conceived.
[10][11] The unfinished quality of the work fits with Michelangelo's late progress away from naturalism and humanism and toward a mystical Neoplatonism, in which he conceived of a sculpture as latent in the marble and requiring merely the removal of superfluous material; in this manner, he seems to have deprived his human symbols of corporeal quality in an attempt to convey directly a purely spiritual idea.
[12] It has also been suggested that the sculpture should not be considered unfinished, but a work in a continuous process of being made visible by the viewer as he or she moves around to see it from multiple angles.
