Subject: Comparative diagrams of the classical orders

These plates remain interesting not for what they describe, but for the method they establish. Comparison becomes a tool of understanding: elements are isolated, aligned, and made legible through juxtaposition. Architecture is translated into a system of relations before becoming a historical narrative.

What emerges is not simply a catalogue of forms, but a historiographic operation — an attempt to grasp complexity through typological comparison. The identification of a type, however, should not be confused with the creation of a canon. Classification clarifies differences; canonization tends to erase them.

Seen today, these diagrams reveal both the power and the limits of comparative history: a method that organizes knowledge while simultaneously decontextualizing information.
