This said, they both betook them several ways 

Gustave Doré made this engraving, This said, they both betook them several ways, using metal plates to create a complex interplay of light and shadow. Doré was a master of line, and here you can see how he built up tone with simple hatching and cross-hatching. Look closely and you will notice that it’s all just lines and dots; no shading at all. This allowed him to achieve incredibly fine detail, from the texture of the robes to the rugged surfaces of the rocks. The image was created through a process that combined artistic skill with commercial production. Doré would draw the design, and then teams of skilled engravers would translate his vision onto wood or metal blocks. These blocks could then be used to print illustrations on a mass scale, which reflects the booming print culture of 19th century Europe. The final result speaks of a collaborative effort, uniting the artist's conception with the craftsman's execution, blurring the lines between fine art and commercial production.
