Prototype. Plates are public domain: Andreas Vesalius, De Humani Corporis Fabrica (1543), via Wikimedia; Henry Vandyke Carter, Gray's Anatomy (1918). Weights shown are approximate, pending a sourced table. The finished piece will draw on Bourgery, Albinus and Gautier d'Agoty from the Wellcome Collection and Gallica.
