DEF

... the ratio into which a line segment must be divided so that the entire length is to the long part as the long part is to the short. The value of the ratio is about 1.618.

CONT

From [the golden section] can be derived the golden number ... 1.618, which was widely claimed in the nineteenth and twentieth centuries to be the key to the beautiful proportions of Greek and other classical architecture.

CONT

Many artists believe that of all rectangles, the one whose length and width make a golden ratio has the most pleasing dimensions; hence the prominence of the golden ratio in architecture, exemplified by the Parthenon.
