Origins Classical architecture is derived from the
architecture of
ancient Greece and ancient Rome. After the
collapse of the western part of the Roman empire, the architectural traditions of the Roman Empire ceased to be practised in large parts of western Europe. In the
Byzantine Empire, however, ancient ways of building methods survived, though they gradually developed into a distinct
Byzantine style. The first conscious attempts to bring back the architectural language of classical antiquity into Western Europe emerged during the
Carolingian Renaissance of the late 8th and 9th centuries. The gatehouse of
Lorsch Abbey () in present-day
Germany features alternating attached columns and arches, a paraphrase of, for example, those of the
Colosseum in Rome. While
Byzantine,
Romanesque, and even to some aspects of
Gothic architecture (with which classical architecture is often posed) incorporate classical elements and details, they generally do not reflect a systematic effort to revive or emulate the architectural principles of antiquity. For instance, they typically do not adhere the idea of
a systematic order of proportions for columns. As such, these styles are not considered classical architecture in the strict sense. During this time period, the study of ancient architecture developed into the architectural theory of classical architecture; somewhat over-simplified, that classical architecture in its variety of forms ever since have been interpretations and elaborations of the architectural rules set down during antiquity. Most of the styles originating in post-
Renaissance Europe can be described as classical architecture. This broad use of the term is employed by Sir
John Summerson in
The Classical Language of Architecture. The elements of classical architecture have been applied in radically different architectural contexts than those for which they were developed, however. For example,
Baroque or
Rococo architecture are styles which, although classical at root, display an architectural language much in their own right. During these periods,
architectural theory still referred to classical ideas but rather less sincerely than during the Renaissance. ==Scope==
