Take a look at how famed Dutch painter Rembrandt used hatching to create shadow and light in this lively little self-portrait (21 x 24 cm). Along the chin and lower jaw you can see how the lines cross over each other , hence the name crosshatching. And for the entire portrait, the more lines on top of each other, the darker it becomes. Notice how the mouth is only rendered in shadow, with no lines around the lips. Also, the nose is left completely open on the light side.
The Spanish artist Goya often used parallel hatching, where the lines do not cross each other but follow the curves of the shapes. Here too, the more lines on top of each other, the darker the shadow. The title of this drawing from 1799 is “Of what evil will he die?” The man in bed will probably die from the doctor’s ignorance because he is depicted as a donkey. The drawing deals with problems in society in Goya’s time that are incurable as long as the authorities (at that time the church and nobility with the army) govern poorly. The bystanders behind the curtain are only visible as silhouettes/shadows (see Chapter 2).
ELABORATIONS:
The correct answer to the question about the hollow tubes in chapter 1 was C.
The light source comes from the right. With A, B and D the drop shadow on the ground is on the light side and that is not correct. With D, also the shadow on the inside of the tube is on the wrong side.
