The Open Timber Roofs of the Middle Ages

Originally published in 1849, this is a detailed study of roof structures, including aesthetic details of churches of the Middle Ages in England. The illustrations are highly detailed drawings of open timber roofs, with measurements, enlarged decorative details, etc. of tie-beam, trussed rafter, hammer beam and collar braced roofs. The work presents working drawings of no fewer than 35 church roofs.
The authors were architects who visited many of the remaining specimens, and selected for illustration those roofs which appeared most worthy of remark, as well as for the excellence of their framing and design, as for affording specimens of the various methods of discussion. Of these the authors have furnished geometrical and perspective drawings from careful measurements taken by themselves.
