Kayleigh.. well said!!
Renaissance art valued much of what we talked about in class, including naturalistic and illusionistic characteristics. Artists aimed to create what they observed, without exaggeration. Working to decieve the eye, artists played with the idea of optics in order to create illusions that would convey realistic works. An example of these illusions is the large hands that Michelangelo sculpted on David so that when viewed from the ground, the hands would appear in proportion with the rest of the body.
Mannerism appears to be less realistic. The people are more slender and their body parts are not in proportion. The artist is creating works based on the way that they want them portrayed, which seems to be more dramatic. The drama can be seen in the painting Modonna of the Long Neck. As the name implys, the woman has a long neck. The "baby" is also completely out of proportion. Michelangelo has influenced many of these works as well. He valued human anatomy and often sculpted/painted humans in contorted, uncomfortable positions, as we see in the sculptures on the Medici tomb. Body parts are elongated and exaggerated. Mannerist artists also bring more light and brightness into their works.
As Renaissance art progresses into Mannerism it seems as though the artist is beginning to gain more control over their own works. As exemplified through Michelangelo's works on the Sistine Chapel ceiling, artists did not always want to create works that were realistic.
