  A statistical study on 565 works of art of different great painters was done
and it was calculated the ratio of the 2 sides of a paintings. Assuming that
all the painters under discussion enter in a statistics with equal weights it
is shown that the average value obtained for the ratio of the sides is 1.34.
This value, determined experimentally is significantly different from the value
of the Golden Section F=1.618, which is a theoretical ratio, obtained from an
abstract, mathematical theory, which supposedly ought to impress on a painting
a supreme harmony.
