The Aisle of the Setting Sun is between the Court of the Universe and
the Court of the Four Seasons.

The Aisle of the Rising Sun is between the Court of the Universe and the
Court of the Ages.

These two aisles are very much alike, the great difference being in the
flora used.

The style is Italian Renaissance and should not be called Venetian, as
many have named it.

The walls are covered with a diaper design of ochre, pink and
travertine.

Blue rondels are used with telling effect. They give a delightful touch
of color and have a fine Italian feeling. These rondels have no special
meaning, being purely decorative.

The coupled columns with different decorations have their prototypes in
the columns of the churches of southern Italy.

The arched windows have interesting grotesque keystones.

Notice that the spirals of the great Siena marble columns turn in
opposite directions. Think how they would appear if they all turned the
same way!

Notice also the beautiful manipulation of color on the Triumphal Arches.
