Rowe's original approach was based on making comparisons between cultural events that conventional history kept widely separated and categorised, but which he unearthed from his vast personal erudition (in constant development) and placed together for comparison. His unorthodox and non-chronological view of history then made it possible for him to develop theoretical speculations such as his famous essay "The Mathematics of the Ideal Villa" (1947) in which he theorised that there were compositional "rules" in Palladio's villas that could be demonstrated to correspond to similar "rules" in Le Corbusier's villas at Poissy and Garches. Although like his MA thesis, this proposal was impossible to support with any evidence, as a speculation it enabled Rowe to elaborate an astonishingly fresh and provocative trans-historical critique of both Palladio and Le Corbusier, in which the architecture of both was assessed not in chronological time, but side by side in the present moment.
