“The whole hand will be the tenth part of the man; From the bottom of the chin to the top of the head is an eighth of its height; From the nipples to the top of the head it will be the fourth part of the height.” If you’re still here without going to get a measuring tape, these phrases were written by Marcus Vitruvius Pollio, a Roman architect who lived in the 1st century BC, who delineated them in his influential treatise “De Architectura Libri Decem” – Ten Books on Architecture. The data presented by Vitruvius was compiled and depicted visually around fifteen hundred years later by Leonardo Da Vinci in his famous work “Vitruvian Man,” which is reproduced in all different contexts today, from book covers to kitchen aprons.
