Study of Cats and Other Animals c. 1513

Da Vinci thought hard about dragons--he pondered most of all the proper placement of their wings. With his superior knowledge of anatomy and physics, he made sure dragon-wings were positioned in the place of arms, rather than appended helicopter-style to the shoulder blades (he drew winged dragons elsewhere; I cannot find the image at the moment).
I require such scientific exactitude in my creatures of fantasy.
Except when they are bumble bees.
