Plague

results in rapid death, within hours, because the massive amounts of bac-
teria overwhelm the body before the victim has time to develop other
symptoms, such as buboes. The outbreak of 1347 may have been predomi-
nantly pneumonic, with some cases of septicemia, based on the descriptions
of observers.
Spread through Europe
The European outbreak of 1347 was heavily documented by many writ-
ers, since literacy was widespread by then. We have records from towns and
cities, parishes, bishops, private individuals who kept journals, and at least
two well-known writers, Petrarch and Boccacio. Boccacio was in Florence
when the plague struck, while Petrarch was in Avignon, where his beloved
Laura died from the plague. We know a great deal about the plague in Italy
and England, where meticulous record keeping went with large-scale com-
merce, but we know relatively less about Spain and Germany.
All sources from around the Mediterranean agree that ships from Genoa
spread the infection fi rst. Genoa had established a colony, called Caffa, on
the Black Sea. It was on the Crimean Peninsula, where modern Feodosia
is located. Inland, the Tartars had conquered Russia, and war broke out
between Caffa and the Tartars. The besieging Tartars caught the plague,
and, as they became too sick to fi ght, they fl ung dead bodies into Caffa.
The plague spread in Caffa, and some escaped in ships and headed back
to Genoa. It is less clear what happened after that because there were re-
ports of Genoese death ships in Constantinople, Sicily, Sardinia, Italian
ports such as Genoa and Naples, and Marseille. It seems unlikely that the
same ships from Caffa called at all these ports, since their crews were dying
rapidly. What is clear is that the trade network, extremely active in the
Mediterranean by the 14th century, rapidly spread the highly contagious
infection.
Constantinople, at the mouth of the Black Sea, was the fi rst region to fall
sick in great numbers. Genoese ships passed through the Aegean Sea and
reached Messina, Sicily. Sicilians rapidly caught the plague, and it passed all
through the island. The Italian peninsula followed, and, at the same time,
the plague entered France through the port of Marseille. It spread rap-
idly through these regions. As the rumor of the Genoese death ships
spread, ports became unwilling to allow ships to stay, and some cities drove
them away violently. The city of Genoa itself drove off its ships with burn-
ing arrows.
The plague was so highly contagious, though, that nothing could hold
back its march through Europe. By the end of 1347, Messina, Marseille,
and Genoa were infected, and a month later, Avignon, Venice, and Ra-
gusa were sick. In March and April of 1348, the plague entered Spain and
