The Ferramenta of the Oculi at Canterbury Cathedral

A groundbreaking discovery at Canterbury Cathedral reveals that the south oculus glass is supported by two layers of ironwork, representing an early form of space-frame construction. This innovative solution addressed the structural challenges posed by larger late Romanesque windows, which traditional armatures could no longer support effectively. The study assesses the significance of this technology and its potential influence across France and Germany, comparing it with subsequent developments in stone tracery. Detailed construction drawings and analysis by Rupert Austin further elucidate the assembly process of the frame.
