The Colosseum in Rome, Charles Michel-Ange Challe, 1742 - 1764
Challe had drawn after antique monuments in Rome while training to be an architect. He drew the Colosseum from many – often original – viewpoints, like this ruined arch, covered in overgrown vegetation. Using a stump, a tightly rolled up cylinder of soft material, he blended the chalk lines to create shadows.
