 For example, Baroque or Rococo architecture are styles which, although classical at root, display an architectural language very much in their own right.During these periods, architectural theory still referred to classical ideas but rather less sincerely than during the Renaissance.The Palladian architecture developed from the style of the Venetian architect Andrea Palladio (1508–1580) had a great influence long after his death, above all in Britain, where it was adopted for many of the grander buildings of the Georgian architecture of the 18th and early 19th century.
