Wharton and Codman believed that architects
and decorators should study works found in Italy after
1500, in France from the time of Louis XIV, and in
England since the introduction of Italian Renaissance
works.
They argued that eighteenth-century French and English
homes, with precedents in Italian architecture, were
the best models for private homes in America. They
also claimed that the interiors of homes must reflect
both historical precedents and contemporary needs.
