The first printer's mark is found in the 1457 Mainz Psalter by Johann Fust and Peter Schöffer. The owner of a printing house in Venice chose a dolphin and an anchor as his publishing mark. The sign is based on the ancient paradox "Hurry slowly" (Latin Festina lente). The dolphin was a sign of speed, the anchor — stability. In addition, both symbols were on the image of port Venice, the capital of the Adriatic.
