The purpose here is to demonstrate the diversity of classical formulae which appeared in architectural design, and if we look at classical architecture as a repertoire of forms rather than statements of specific design credos we can challenge teleological constructions of stylistic histories. The method of grouping the architecture from given periods of time under general stylistic labels has, without doubt, been the backbone of the discipline of architectural history. And when used skilfully and carefully it can provide useful punctuation marks in the lengthy and complex narrative that is the subject-matter of the history of western building. Yet it is only one of many tools with which to explore social and cultural contexts.
