The men of Renaissance Florence were so renowned for sodomy that "Florenzer" in German meant "sodomite." Indeed, in the late fifteenth century, as many as one in two Florentine men had come to the attention of the authorities for sodomy by the time they were thirty. In the seventy years from 1432 to 1502, some 17,000 men - in a city of only 40,000 - were investigated for sodomy; 3,000 were convicted and thousands more confessed to gain amnesty.

Michael Rocke vividly depicts this vibrant sexual culture in a world where these same-sex acts were not the deviant transgressions of a small minority, but an integral part of a normal masculine identity.

Rocke uncovers a culture in which sexual roles were strictly defined by age, with boys under eighteen the "passive" participants in sodomy, youths in their twenties and older men the "active" participants, and most men at the age of thirty marrying women, their days of sexual frivolity with boys largely over. Such same sex activities were viewed as a normal phase in the transition to adulthood, and only a few pursued them much further.

Rather than precluding heterosexual experiences, they were considered an extension of youthful and masculine lust and desire. As Niccolo Machiavelli quipped about a handsome man, "When young he lured husbands away from their wives, and now he lures wives away from their husbands." Florentines generally accepted sodomy as a common misdemeanor, to be punished with a fine, rather than as a deadly sin and a transgression against nature.

There is no word, in the otherwise rich Florentine sexual lexicon, for "homosexual," nor is there a distinctive and well-developed homosexual "subculture." Rather, sexual acts between men and boys were an integral feature of the dominant culture.

Rocke roots this sexual activity in the broader context of Renaissance Florence, with its social networks of families, juvenile gangs, neighbors, patronage, guilds, and confraternities, and its busy political life from the early years of the Republic through the period of Lorenzo de' Medici, Savonarola, and the beginning of Medici princely rule.
