Answer:
Modeling is a term in art that refers to the technique of creating the illusion of three-dimensional objects on a two-dimensional surface. In this technique, an artist uses shading, highlights, and shadows to create the illusion of depth, volume, and texture.
Michelangelo was considered a master of modeling because of his exceptional ability to create a sense of volume and mass in his works of art. He was able to achieve this by using a technique called "chiaroscuro," which is the use of strong contrasts between light and dark to create the illusion of three-dimensionality.
In The Holy Family, Michelangelo's use of modeling is evident in the way he depicts the figures of Mary, Joseph, and the baby Jesus. The figures have a strong sense of volume and are depicted as three-dimensional objects rather than flat shapes on a surface.
Additionally, Michelangelo's use of modeling is also evident in the way he depicts the folds of the drapery in the background. The folds have a sense of weight and depth, creating a more realistic and convincing illusion of space.
Overall, Michelangelo's exceptional ability to use modeling to create the illusion of three-dimensional space and form is what made him a master of this technique.
