3. The fascinating meaning of Vitruvian
Man by Da Vinci
• Leonardo da Vinci's Vitruvian man is one of the most well-known images of Renaissance
art, which may be a bit surprising since it seems to be just a pencil and ink drawing of a
man with superimposed limbs inside a circle and a square . However, this drawing is
much more than that; it´s the symbolic solution of Leonardo to an ancient mathematical
problem that had some importance also in alchemy, in what is known as "squaring the
circle."
4. The Roman architect Marco Vitruvius found all kinds of
mathematical proportions in the human body, which he
considred as the measure of all architectural construction,
following the old dictum that man is the measure of all
things: "No symmetry and no proportion Temple can have
a regular plan, that is, it must have an exact ratio drawn
from the members of a well-formed human figure“. Much
has been speculated that many of the great temples of
antiquity kept the golden ratio.
