Meanwhile the position of the Jews grew constantly more deplorable. Decimated and impoverished, they were met by a steadily increasing temper of hatred and oppression. The massacres of 1391 had been followed by a constant stream of emigration to Granada and Portugal, which threatened to complete the depopulation of the aljamas and, with the view of arresting this, Henry III, in 1395, promised them the royal protection for the future. The worth of that promise was seen in 1406, when in Córdova the remnant of the Judería was again assailed by the mob, hundreds of Jews were slain and their houses were sacked and burnt. It is true that the king ordered the magistrates to punish the guilty and expressed his displeasure by a fine of twenty-four thousand doblas on the city, but he had, the year before, in the Córtes of 1405, assented to a series of laws depriving the Jews at once of property and of defence, by declaring void all bonds of Christians held by them, reducing to one-half all debts due to them and requiring a Christian witness and the debtor's acknowledgement for the other half, annulling their privileges in the trial of mixed cases and requiring the hateful red circle to be worn except in travelling, when it could be laid aside in view of the murders which it invited.[337] This was cruel enough, yet it was but a foretaste of what was in store. In 1410, when the Queen-regent Doña Catalina was in Segovia, there was revealed a sacrilegious attempt by some Jews to maltreat a consecrated host. The story was that the sacristan of San Fagun had pledged it as security for a loan--the street in which the bargain was made acquiring in consequence the name of _Calle del Mal Consejo_. The Jews cast it repeatedly into a boiling caldron, when it persistently arose and remained suspended in the air, a miracle which so impressed some of them that they were converted and carried the form to the Dominican convent and related the facts. The wafer was piously administered in communion to a child who died in three days. Doña Catalina instituted a vigorous investigation which implicated Don Mayr, one of the most prominent Jews in the kingdom, whose services as physician had prolonged the life of the late king. He was subjected to torture sufficient to elicit not only his participation in the sacrilege but also that he had poisoned his royal master. The convicts were drawn through the streets and quartered, as were also some others who in revenge had attempted to poison Juan de Tordesillas, the Bishop of Segovia. The Jewish synagogue was converted into the church of Corpus Christi and an annual procession still commemorates the event. San Vicente Ferrer turned it to good account, for we are told that in 1411 he almost destroyed the remnants of Judaism in the bishopric.[338] [Sidenote: _OPPRESSION OF THE JEWS_]
