The Black Death's first blow started in 1348 in Ragusa, we now call Dubrovnik, spreading to all of Europe. Ships likewise were made to anchor off the coast to be sure the crew and their goods were not infected. Residents were barred from visiting them. The order was copied into the city’s lawbook, the Liber Viridis, or “Green Book,” which still survives in Dubrovnik’s archives. The word still survives too: quarantine from quaranta, Italian for 40.
