This paper compares the interior spaces of the Great Halls of four Roman baths (Diocletian, Constantine, Caracalla and Agrippa), as documented in Palladio’s reconstruction drawings, to the interior space of the nave of his Venetian church, Il Redentore. Three-dimensional computer models based on these reconstruction drawings then are compared to 3D computer models of the Il Redentore nave and side chapels. An interactive interface provides fresh insight into the architect’s previously unexamined late design processes, and allows viewers to compare similarities in composition, form, and proportion by overlaying plan, sections and scaled 3D models of the bath’s Great Halls and the Il Redentore interior. While it is well known that the design of Palladio’s buildings, particularly his villas, drew many of their features from Roman architecture, this paper analyzes the design sources for the Il Redentore nave and side chapels and finds previously uninvestigated similarities in their form, composition, and proportions to the Great Halls of the Roman baths that a young, aspiring architect carefully documented, then studied closely.

本文将 Palladio 重建图纸中记载的四个罗马浴场（戴克里先、君士坦丁、卡拉卡拉和阿格里帕）的大厅内部空间与他的威尼斯教堂 Il Redentore 中殿的内部空间进行了比较。然后将基于这些重建图的三维计算机模型与 Il Redentore 中殿和侧礼拜堂的 3D 计算机模型进行比较。交互式界面提供了对建筑师以前未经审查的后期设计过程的新见解，并允许观众通过叠加浴室大厅和 Il Redentore 内部的平面图、剖面和缩放 3D 模型来比较构图、形式和比例的相似之处。众所周知，帕拉迪奥的建筑设计，尤其是他的别墅，从罗马建筑中汲取了许多特色，
