Rococo

Rococo was an art style of the 18th century aristocracy.  Women, particularly,
Madame de Pompadour were very instrumental in the development of
this movement of the 18th century, which incorporated lots of
feminine motifs.  The Rococo movement was first evidenced in 
the architecture and interior design of the elite monarch and then
later in the painting styles of Rigaud, Watteau, Fragonard, and 
Boucher.

In "The Swing" by Jean-Honore Fragonard, the pastel colors, white
porcelain figures, and escapist content can be seen as  typical examples of 
the Rococo style.

Rococo was a term derived from the french word "rocaille" which
means pebbles or shells, which are an intregal part of the ornate
motifs of this style.

Neoclassicism

The Neoclassical movement was an art style of the French Revolution.
Jacques Louis David was the first or premier painter to Napoleon.
Artists of this time period chose to reflect an art that coresponded
to the politics of the time.  The politics of the French Revolution
were based on Greek and Roman models, thus, the artists looked by
to Ancient times for artistic inspiration.  In the "Death of Marat,"
the political idealism, formal balance, and message of self-sacrifice
for politics and country are evident.  The figure is sculpturesque,
idealized, and wears a turbin.  He has given his life for the "cause,"
and all the action takes place within an interior setting, with 
a strong stage-like pose.  "George Washington," by Horation Greenough,
and "The Oath of the Horatii," are two other good examples of
this 19th century style which opened the door to modern art.
