The glimpse of good fortune which the Spanish Jews enjoyed under Alfonso XI served only to bring down upon their brethren in the other Christian countries a widespread, intense, indescribably cruel persecution with which none of the massacres that had hitherto taken place can be compared. The destroying angel called the Black Death, which carried on its ravages for over three years, made its way from China across lands and seas into the heart of Europe, heralded by premonitory earthquakes and other terrifying natural phenomena. Sparing neither rank nor age, it left a devastated track behind, sweeping away a fourth part of all mankind (nearly 25,000,000) as with a poison-laden breath and stifling every noble impulse. In Europe the invisible Death with its horrors turned the Christians into veritable destroying angels for the Jews. Those whom the epidemic had spared were handed over to torture, the sword, or the stake. Whilst neither Mahometans nor Mongols who suffered from the plague attacked the Jews, Christian peoples charged the unhappy race with being the originators of the pestilence, and slaughtered them _en masse_. The church had so often and impressively preached that infidels were to be destroyed; that Jews were worse than heretics, even worse than unbelieving heathens; that they were the murderers of Christians and the slayers of children, that at last its true sons believed what was said, and carried its doctrines into effect. Owing to the prevailing misery, discipline and order, obedience and submissiveness were at an end, and each man was thrown upon his own resources. Under these circumstances, the effects of the education of the church appeared in a most hideous form. The Black Death had indeed made itself felt among Jews also; but the plague had visited them in a comparatively milder form than the Christians, probably on account of their greater moderation, and the very careful attention paid their sick. Thus the suspicion arose that the Jews had poisoned the brooks and wells, and even the air, in order to annihilate the Christians of every country at one blow.
