Instructions du Comité historique des arts et monuments. Architecture gallo-romaine et architecture du moyen age
An 1857 Paris instruction manual issued by the French Comité historique des arts et monuments, compiled under Prosper Mérimée to guide surveyors recording Gallo-Roman and medieval architecture. The pictures are plain engraved line drawings of pilasters, a pointed arch with stepped moulded orders and foliate capitals, arch and vault sections, and arcade elevations, with lettered figures for comparison. A designer could draw from their clean hatched linework and the simple, legible way each structural profile is set out for measurement.
