Similarly, in sculptures, most of the weight seems to on one foot, which also results in this slanted position,
making it seem like the figure is about to walk or move.
This adds to the realistic aspect of the figure.
But there are actually a lot of things that could go wrong in the attempt to create such a pose.
You could make a figure’s arms bigger than its legs, or the head too small for the body.
Messing up the proportions can leave a figure looking cartoon-like and unnatural.
But Alberti had a solution. He encouraged artists to visualize a figure’s bones and structure.
This would give the artist an idea of the proportions of the figure.
From there, Alberti suggested that the artists imagine attaching the tendons and muscles, then covering those with flesh and skin.
