A 1655 Roman engraved folio by Pietro Santi Bartoli, published by Giovanni Giacomo de Rossi, reproducing monochrome grisaille frescoes in the Sala di Costantino of the Vatican Palace, painted after designs by Giulio Romano under Clement VII and nearly lost to age. The pictures are a sequence of long horizontal friezes of battle, march and river crossing scenes, with crowded figures, horses, chariots and soldiers in dense black-and-white line engraving, showing a designer how historical narrative bands were organised across a wall.
