Illustration from Rules and Examples of Perspective proper for Painters and Architects, etc. In English and Latin: Containing a most easie and expeditious method to delineate in perspective all designs relating to architecture

Si laquear sit quadratum, & valde distans ab oculo, architecturam huic similem in eo depingere licebit. A est elevatio geometrica; eadem verò deformata in B & C, gerit munus vestigii & elevationis. Medietas unius ex quatuor partibus, usui esse potest in toto opere, aut premendo chartam, aut eâ perforatâ, immittendo per foramina carbonem minutissimè contusum.
