This is the first translation into English of Juan Bautista Villalpando's Book Five of In Ezechielem Explanationes et Apparatus Vrbis Templi Hierosolymitani. After its publication in 1604 the work stimulated a debate-over not only the architecture of Solomon's Temple but on the very nature of the origins of architecture-that endured for more than one hundred and fifty years, in the form of commentaries and other reconstructions.
