La révolution nautique médiévale : l’exemple génois

Abstract

This article explores the “medieval nautical revolution” through the Genoese perspective, expanding on Frédéric Lane’s work. Key innovations, including the compass, portolan charts, square rigging, and the stern rudder, enhanced maritime efficiency by reducing costs and increasing cargo capacity. Genoa’s early adoption of the cocca, influenced by Northern koggen, revolutionized the transport of heavy goods like alum. Notarial records provide insights into ship types and construction, contrasting Genoese practices with Venetian approaches. The evolution of military galleys from biremes to triremes also improved speed and capacity. The study emphasizes Genoa’s pivotal role in reshaping medieval Mediterranean trade networks.
