Vitruvius Pollio

De Arhitectura, 1521

Vitruvius is famous for asserting in his book “De architectura” that a structure must exhibit the three qualities of firmitas, utilitas, venustas – that is, it must be solid, useful, beautiful. These are sometimes termed the Vitruvian virtues or the Vitruvian Triad.

Leonardo DaVinci

L’Uomo Vitruviano, 1940

Drawn around 1940 by Leonardo DaVinci and based on the previous works of the architect Vitruvius.

The image demonstrates the proportions of human body-parts to the hole body, blending mathematical measurings from art and architecture. The drawing represents the symmetry of the human body and that of the universe.
