We received a letter written by Matteo Palmieri, captain of Volterra, which I saw and read; it related the following marvel, namely, that in these days there had been born in Volterra a boy (that is, a monster) which had the head of a bull, and three teeth, with a lump of skin on the head like a horn, and the top of the head was open like a pomegranate, with fiery rays coming out. Its arms were all hairy, and its feet were like a lion's with lion's claws. Its body was of the nature of a female of the human race, but its legs down to the feet were those of a bull like the head. And it lived about three hours. The mother died the fourth day. The midwives and the other women present half died of fried. And this was shown to the said Matteo as a terrible thing. And the said Matteo, captain of Volterra, wrote here to Florence with his own hand; and I copied the said letter in the actual words, neither omitting nor adding anything. And because the said Matteo was my father's intimate friend and my godfather, the letter itself came into my hands, although it was directed to other citizens.
There was an eclipse of the moon. And it happened that three people fell dead on this day: a boy about twelve years old, whom I myself saw lying dead in the church of San Simone, a notary called Ser Bonacorso, and a girl. It was considered in Florence to have been an extraordinary day, the moon having had a powerful influence.
