Life drawing classes are the traditional method for teaching the drawing of the human figure. Live models are used so that students can study the muscles and anatomy of the figure in order to render the volume and dimensionality of the human body. Using photographs instead of models can often cause students to render the figure in too flat a manner.
Drawing classes that I attended at York College, CUNY, in Queens NY in the 1970’s, were held in 4-hour segments. Poses were held for short bursts of sketching time such as 5 or 15 minutes in the early part of a class to allow the artists time to warm up their drawing arm and eye. As the class progressed, poses often were held for longer periods and were in fact upon many occasions maintained for the entire remainder of the session. When the model took a break they would then return to their position in the center of the class so the students could continue to work on the drawing of that pose.
Life drawing is such an fundamental part of the curriculum of any art school that it is hard to believe that in the not so distant past these classes were taboo for women. Throughout history women were banned from traditional art school under the guise of protecting their delicate sensibilities. In order to pursue their art many women took a separate path towards expressing themselves and gravitated to watercolor paintings of flowers and gardens. These were considered acceptable mediums and subjects for a well-protected and well brought up middle class woman.
And then along came Georgia O’Keeffe and everyone saw flowers in a very different way. She helped to forge an acceptance of woman as artist and the doors of art schools flew open.
