At that time they contributed 25,000 florins monthly to Venice, maintained full garrisons in the fortresses of the republic, and paid as well for upwards of 1,000 men at arms.

In order that a correct notion of these balance-sheets may be obtained, Villani is careful to give particulars about the value of the florin and the lira, and the number of florins coined yearly.

In describing the condition of Florence at this period, he computes the number of citizens capable of bearing arms, between the ages fifteen and seventy, at 25,000; the population of the city at 90,000, not counting the monastic communities, nor including the strangers, who are estimated at about 15,000.

The country districts belonging to Florence add 80,000 to this calculation.

It is further noticed that the excess of male births over female was between 300 and 500 yearly in Florence, that from 8,000 to 10,000 boys and girls learned to read; that there were six schools, in which from 10,000 to 12,000 children learned arithmetic; and four high schools, in which from 550 to 600 learned grammar and logic.
Then follows a list of the religious houses and churches: among the charitable institutions are reckoned 30 hospitals capable of receiving more than 1,000 sick people.
