In 1098 Crusader destruction of the Syrian town of Ma'arra had been accompanied by acknowledged acts of Frankish cannibalism. Graphically described in the chronicle of Radulph of Caen (he admits that "In Ma'arra our troops boiled pagan adults in cooking pots; they impaled children on spits and devoured them grilled"), they were later "justified" in a letter sent to the Pope by the Christian commander, who blamed the lapse on extreme hunger. Needless to say, this excuse was dismissed by Arab historians who continued to describe their bloodthirsty enemies as eaters not only of people, but, what was worse, even of dogs, considered the uncleanest of species (Maalouf, 1984: 39-40).
