Die architektonischen Stylarten, eine kurze, allgemeinfassliche Darstellung der charakteristischen Verschiedenheiten der architektonischen Stylarten ..
Albert Rosengarten's 1869 Braunschweig survey of architectural styles, written in German for a general readership, compares building styles through elevation drawings. The pictures are plain black-and-white facade elevations of palaces and towers in different periods, set side by side so a designer can compare window forms, arcades, and wall articulation across eras.
