”…took to deriding the Christians and Christ Himself in their boasting; they ridiculed the cross and anyone trusting in the crucifix, putting the following joke in practice. “They took a Christian child, tied it to a cross and hanged him. Initially they made him the object of jokes and drollery; then, after a while, they lost control of themselves and mistreated him to such a degree that they killed him." The report, which makes no mention of miracles occurring at the site of the relics of the martyred child, seems to possess all the indications of truthfulness. Moreover, as we have seen above, there are people who have viewed the immoderate celebrations of Purim, accompanied by anti-Christian insults and violence, as the core from which the belief in Jewish ritual homicide of Christian children is thought to have developed during the Middle Ages, as an integral part of a ritual centered around on the festival of Pesach, considered the ideal culmination of Purim (33).
