Principles of beauty, relative to the human head
Principles of beauty, relative to the human head is a 1778 London drawing manual by Alexander Cozens, with plates engraved by Francesco Bartolozzi, aimed at students of artistic anatomy. Its plates show profile heads in outline, with hair drawn as flowing, ribboned masses and a few sketches of head forms reduced to simple shapes, so a designer could take a clear method for building hair, brow and profile line from them.
