Jefferson wanted a glass roof on the South Wing, based on his dazzling memory
of a 1785 visit to the Paris grain market with Maria Cosway. He later wrote that the
grain market was, "... the most superb thing on earth."
Architect Latrobe disagreed with his client on the roof design. To accommodate
both the skylight scheme and his own idea for a light monitor of vertical glass, he framed the
roof for both eventualities.

called the domical wooden roof a masterpiece of carpentry.

Two images of computer model showing the Jefferson idea for the roof
and the Latrobe idea for the roof. Jefferson's idea was designed and built and that's what
was destroyed in 1814 when the building burned.

The skylight version upon entry. Latrobe considered this
tableau to be the crowning achievement of the whole chamber. The sculpture was an organic
feature of the design - it was largely designed by Latrobe and carved by Giuseppe Franzoni.
