The remarkable engraved title page for Dupont's book reflects Dupont's historical interests. On the top is the inventor of printing from movable type, Gutenberg. On the left is a plaque for the famous Elzevir press; on the right for the Didot printing dynasty at which Dupont apprenticed. Beneath the curtain we see Dupont's rather enormous printing facility. Putti at the top of the ornate design work a modern cylinder press on the left and a Stanhope press on the right. In the lower left we see typesetting equipment and on the right finished books and perhaps manuscripts.
