Helios der Titan, oder, Rom und Neapel : eine Zeitschrift aus Italien
Helios der Titan, oder, Rom und Neapel is a German periodical printed in Leipzig by H. Gräff in 1802, written by Karl Friedrich Benkowitz as a travel journal about Rome and Naples. Its three plates are plain line diagrams of engineering or architectural layouts on pages of printed text, with no shading, showing how a designer could borrow simple schematic and plan-drawing conventions.
