Teach anatomy through the masters, not the cadaver
Used drawings by Michelangelo, Rubens, and Leonardo as the anatomy textbook, showing what the masters selected, exaggerated, and left out, rather than teaching medical completeness.
Why it matters · Artistic anatomy is a set of decisions, not an inventory. Studying the decisions inside master drawings teaches which anatomical facts matter for a convincing figure and which are noise, which is the difference between an artist's anatomy and a surgeon's.
Robert Beverly Hale, Drawing Lessons from the Great Masters (Watson-Guptill), 1964
Conceive every form as a simple solid
Reduced each part of the figure to a block, sphere, cylinder, or egg before considering its anatomy, and insisted the masters thought in these terms.
Why it matters · A simple solid has knowable planes, so its light is predictable and its perspective is drawable. Once the thigh is a cylinder, you can turn it, light it, and foreshorten it from imagination; as raw anatomy it is unmanageable.
Robert Beverly Hale, Master Class in Figure Drawing (Watson-Guptill, ed. Terence Coyle), 1985
Carry the long line through the figure
Favoured long, continuous directional lines that run through multiple forms, subordinating small bumps to the big sweep of the limb or torso.
Why it matters · Beginners draw the figure bump by bump and lose the gesture. The long line keeps the drawing organised around direction and flow, and the small forms read as variations on it rather than interruptions.
Robert Beverly Hale, Master Class in Figure Drawing (the lecture demonstrations), 1985
Run the light over the form by logic
Taught light as geometry: once a form is a known solid with known planes, the values on it follow from the light's direction, and can be reasoned rather than copied.
Why it matters · It frees the artist from the model. If value is a consequence of plane and light direction, you can light a figure from imagination, correct a photograph's bad lighting, and know why a passage looks wrong instead of guessing.
Robert Beverly Hale, Drawing Lessons from the Great Masters (the light-on-form chapters), 1964
Demonstrate at scale, at the blackboard
Delivered the famous League lectures drawing on a blackboard with a skeleton beside him, constructing the figure large, in front of hundreds, while narrating the reasoning.
Why it matters · The lecture format forced the method to be explicit: every mark had to be explainable out loud. That is why the posthumous transcriptions work as books, and why his students absorbed a way of reasoning rather than a set of tricks.
