An essay on the invention of engraving and printing in chiaro oscuro, as practised by Albert Durer, Hugo di Carpi, &c. and the application of it to the making paper hangings of taste, duration, and elegance
A 1754 London treatise by the woodcut printer John Baptist Jackson arguing for chiaro oscuro engraving and its use in printed wallpaper, issued for print collectors, connoisseurs and the decorating trade. The plates carry bearded heads and draped figures printed in brown and olive tone blocks, with washy tonal masses instead of outline, alongside engraved headpieces of paired birds and scrollwork framing a profile medallion. Useful for muted two-colour tonal shading and ornamental frames.
