Those chapters of the _Sirr-el-asrar_ which relate to regimen were translated into Latin by Johannes Hispalensis. Jourdain identifies this author with John Avendeath, who worked for the Archbishop of Toledo between the years 1130 and 1150.[70] But Foerster shows that caution is needed here.[71] The Latin version was dedicated to Tarasia, Queen of Spain. A queen of this name certainly lived contemporaneously with John Avendeath, but she was Queen of Portugal. Another Tarasia, however, was Queen of Leon from 1176 to 1180. We may observe that this latter epoch agrees well enough with the lifetime of Ibn Butrus, who died in 1217, and we find trace of another Johannes Hispanus, who was a monk of Mount Tabor in 1175. Such a man, who from his situation in Syria could scarcely have been ignorant of Arabic, and whose nationality agrees so well with a dedication to the Queen of Spain, and who was a contemporary of Tarasia of Leon, may well have translated the _Sirr-el-asrar_ into Latin. That part of the book thus made public in the West appeared under the following title: ‘De conservatione corporis humani, ad Alexandrum.’ It is found in several manuscripts of the Laurentian Library in Florence.[72] Soon afterwards, and probably in the opening years of the thirteenth century, the whole book was published in a Latin version by the same Philippus Clericus, with whom we have already become acquainted. We may recall the fact that he belonged to the diocese of Tripoli, as Ibn Butrus also did, and as Johannes Hispanus was also a monk of Syria, these three scholars are seen to be joined by a link of locality highly increasing the probability that they actually co-operated in the publication of this hitherto unknown text. In his preface, Philip speaks of the Arabic manuscript as a precious pearl, discovered while he was still in Syria. This leads us to think that his work in translating it was done after he had left the East, and possibly in the course of his voyage westward. We know that the Hebrew version of Aristotle’s _Meteora_ was produced in similar circumstances. Samuel ben Juda ben Tibbun says he completed that translation in the year 1210, while the ship that bore him from Alexandria to Spain was passing between the isles of Lampadusa and Pantellaria.[73] However this may be, Philip of Tripoli dedicated his version of the _Sirr-el-asrar_, which he called the _Secreta Secretorum_, to the Bishop under whom he had hitherto lived and laboured: ‘Guidoni vere de Valentia, civitatis Tripolis glorioso pontifici’: a name and title little understood by the copyists, who have subjected them to strange corruptions.[74]
