The renowned notebook of the twelfth-century architect Villard de Honnecourt contains some deleted diagrams, which have been studied by Roland Bechmann. An infra-red photograph of a page revealing an erased drawing of a pointed arch is reproduced as Fig. 25, a redrawn diagram is given as Fig. 26 and an enhanced version (with supplementary constructions) is given as Fig. 27. That enhanced version includes a simple geometrical construction of a line AE, with the radius of each of the semi-circles labelled as R.
