There as some unique similarities in the context of each of these works, since they could all be viewed as symbols of sadness and loss. The Pietà portrays sadness in the eyes of Mary the mother of Jesus as she holds her sons limp, lifeless body after the crucifixion is that her "youth symbolizes her incorruptible purity, as Michelangelo himself said to his biographer and fellow sculptor Ascanio Condivi." (Wikipedia, 2007). The Crouching Boy is curled up, described as having a lot of tension and may be the symbol of a wounded soldier. The Monument is a tomb for the vicory of Naples, Don Pedro of Toledo, again showing the end of a person 's life as in The Pietà and therefore the loss of the leader.
The main focus of each work can be viewed differently depending on your outlook. In the Pietà, the main focus could be Mary or Jesus. Mary because of the expression on her face as she looks down on her son as she cradles his body or Jesus and the finality of his human life and suffering he endured. Similar differences are found in the Monument. One could suspect that the main focus of the tomb and statues is the representation of the headdress in the middle of the tomb. This symbolizes the status and position of the person who has been laid to rest or the focus could be the strength and adornment shown to the deceased by the figures who surround the tomb and protect it. The Crouching Boy is an unfinished work by Michelangelo and many have tried to guess what he was saying. It is in cubic form and seems constrained or could it be a wounded soldier or a spirit of mourning. (Hermitage
