 With the decline of the Roman Empire, and its replacement by various barbarian kingdoms, a general tolerance (with the sole exception of Visigothic Spain) for homosexual acts prevailed. As one prominent scholar puts it, “European secular law contained few measures against homosexuality until the middle of the thirteenth century.” (Greenberg, 1988, 260) Even while some Christian theologians continued to denounce nonprocreative sexuality, including same-sex acts, a genre of homophilic literature, especially among the clergy, developed in the eleventh and twelfth centuries (Boswell, 1980, chapters 8 and 9).
