Summary :
IN 1346, wrote the Florentine chronicler Matteo Villani, Mars, Jupiter, and Saturn conjoined in Aquarius. In the same year a wave of pestilence appeared in the East, "toward Cathay and northern India," and began to spread westward. It was a plague which touched people of every condition, age, and sex. They began to spit blood and then they died—some immediately, some in two or three days, and some in a longer time. And it happened that whoever cared for the sick caught the disease from them or, infected by the same corrupt air, became rapidly ill and died in the same way. Most had swellings in the groin, and many had them in the left and right armpits and other places; one could almost always find an unusual swelling somewhere on the victim's body.1
