Colour is rare in Leonardo’s anatomical drawings, but in his late embryological studies of the fetus he used red chalk to evoke the coiled potential of the child in the womb. Though Leonardo does seem to have dissected a woman who had died in pregnancy, many of the structures seen here are based on his earlier dissection of a pregnant cow.
