12th century scholar

John of Seville (Latin: Johannes Hispalensis or Johannes Hispaniensis) (fl. 1133 53) was one of the main translators from Arabic into Castilian in partnership with Dominicus Gundissalinus during the early days of the Toledo School of Translators. John of Seville translated a litany of Arabic astrological works in addition to being credited with the production of several original works in Latin.

John of Seville was a baptized Jew, whose Jewish name (now unknown) has been corrupted into "Avendeut", "Avendehut", "Avendar" or "Aven Daud". This evolved into the middle name "David", so that, as a native of Toledo, he is frequently referred to as Johannes (David) Toletanus. His date of death is sometimes placed around 1157, but this remains an uncertainty. as well as the Arab astrologer Albohali's "Book of Birth" into Latin in 1153. This also includes the work to translate another one of Al Farghani’s works titled Kitāb fī Jawāmiʿ ʿIlm al Nujūm ("Elements of astronomy on the celestial motions"). He also translated Kitāb taḥāwīl sinī al ‘ālam ("Flowers of Abu Ma'shar") by Abu Ma'shar al Balkhi into Latin. More notable works of John of Seville include the translations of a manuscript in the library of St. Marks, the Greater Introduction of Albumasar, and the engraved written work of Thebit. Another work that is attributed to John of Seville through a note in the beginning of one of the margins is from Astroligi(c)e speculationis exercitium habere volentibus, which now resides at Pommersfelden in an upper Bamberg district in Germany.

At least three of his translations, a short version of the Secretum Secretorum dedicated to a Queen Tarasia, a tract on gout offered to one of the Popes Gregory, and the original version of the 9th century Arabic philosopher Qusta ibn Luqa's De differentia spiritus et animae (The Difference Between the Spirit and the Soul), were medical translations intermixed with alchemy in the Hispano Arabic tradition. His partial translation of the Secretum Secretorum is considered to be his earliest known work. Unlike much of his later work, this translation utilizes a first person perspective. Another notable work translated by John of Seville from arabic is the Emerald Tablet, an alchemical work of the Hermetic tradition that is originally credited to Hermes Trismegistus himself, it was said to contain many alchemical secrets.

In addition to his many translations John of Seville is credited with a work of his own titled, Epitome artis astrologiae, written in 1142 which is a summary of astrology as a whole.

The work of John of Seville was later preserved by medieval scholars through the copying of his translations. These copies occasionally deviate from John's original text, producing errors that further perpetuate the issue of John's identity. When the name of a translator was improperly copied into a manuscript, further copies of this manuscript would carry this error, initiating a mutation of names and dates over the span of multiple copies. Carelessness further complicated the matter. Abbreviations such as "Ioh Hisp" (Iohannes Hispalensis was yet another possible identity for John) were used, such as in a manuscript from 1503. Fortunately, a number of factors have aided in determining whether certain translations belong to John of Seville. He would often sign his translations "Cum laude Dei et eius adiutorio," making otherwise error ridden manuscripts easily attributable to John.
