Peter Conrad in The Guardian:
Forbidden Desire, Noel Malcolm’s sober and footnote-heavy history of male homosexuality between 1400 and 1750, has some friskier bedfellows: on Amazon it shares its title with a slew of hairy chested bromances, one or two Sapphic romps, and a sulphurous tale about a witch’s affair with a tormented demon. Against such competition, Malcolm fields a cast that includes lustful Turkish potentates, predatory Catholic priests, corruptible scullions and smooth-cheeked choristers, together with two English kings who allegedly fooled around with virile young favourites. But mostly the sodomites, as Malcolm grimly insists on calling them, are left to satisfy their desires in private; the historian’s concern is the forbidding religious commandments that the same-sex couples flouted and the crazily brutal penalties imposed by laws that purported to uphold the divine order of the universe.
Sex here seems to be followed, almost automatically, by excruciating death. In the 15th century, sodomy in Venice was punished by decapitation, after which the corpses of the malefactors were burned to ensure that no trace of them remained. Because it was unlawful to kill an ordained man, a lecherous cleric was locked in a cage in the Piazza San Marco and left to starve in full view of a gloating populace. In Florence a boy aged 15 was castrated on the scaffold, then fatally sodomised with a hot iron poker. A Dutch youth placed in the pillory was pelted with filth and bombarded with stones, which finally finished him off. Others were sentenced to row themselves to death as galley slaves; the lucky ones, in a bizarre act of mercy, had their noses, not their heads or penises, chopped off.
