It was translated into Hebrew, under the title Gerem ha-Ma'alot, by Benveniste's son, Joseph Vidal.
This Joshua al-Lorqui is perhaps, as Philoxene Luzzatto points out, identical with the Joshua al-Lorqui who wrote an anti-Christian letter to his friend Solomon ha-Levi (Paul de Burgos), and who was also a physician in Alcañiz and was on friendly terms with Benveniste ben Labi, being present at Moses Benveniste's wedding.
In the letter the writer expresses his astonishment at the fact that Paul de Burgos should have resolved to change his faith; he investigates the motives which could have led him to take such a step—ambition, mania for wealth and power, satisfaction of sensual desires, doubt of the truths of Judaism.
This letter was addressed to Paul de Burgos at a time when the latter occupied a high position, was surrounded by luxury and a band of servants, and, as is supposed, had already been appointed tutor to the young king Juan II of Castile.
[1] His son, also Joseph ben Joshua ibn Vives al-Lorqui, was also a physician, and died before 1408.
