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.
