John James translation

Optica imminutio capitelli Etrusci.

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

Eâdem cum reliquis formâ, eâdemque methodo capitella delineanda sunt: quum habeant ipsa quoque suum cimatium quadratum, & sint rotunda. Linea plani solet in iis fieri altior lineâ horizontali: quia quum capitella imponenda sint columnis homine altioribus, plerumque apparent sublimiora nostris oculis.
