The changing designs of the capitals from Ancient Greece to the Romanesque period reflect the cycle of architectural design peaking and then reverting back to simpler design types. The styles of capitals were clearly defined in the Greco-Roman period which required skilled laborers to create them. During the Byzantine period, the capitals became more varied which is speculated to be due to experimentation. In the Romanesque era, leaves on capitals that appear to be derived from the Corinthian style are present in the Abbey Church of Sainte Foy in France. These stylistic variations were indicative of the larger concept of an architectural design cycle.
