Natura artis studio feliciter repraesentata, sive, Humana statura per singula membra juxta aetates et sexus nova inventione accuratissime delineata = oder, Gründlich und vollkommene Anweisung zum Zeichnen und kunstmässige völlige Ausarbeitung menschlicher Statur ...
An early eighteenth-century Latin and German drawing manual by Johann Daniel Hertz, published in Augsburg in 1723, teaching artists to draw the human figure limb by limb across ages and sexes. The plates are engraved studies of feet, hands and arms, shown in several angles on one sheet, with light cross-hatching to model the forms. A designer could borrow the method of breaking the body into isolated parts and sketching each from multiple views to build a reference sheet.
