Influence
In 956 his pupil Dunash Ibn Tamim wrote an extensive commentary on Sefer Yetzirah, a mystical work of cosmogony which attributes great importance to the letters of the Hebrew alphabet and their combinations in determining the structure of the universe. In this work he cites Israeli so extensively that a few nineteenth century scholars misidentified the commentary as Israeli's.
Israeli's medical treatises were studied for several centuries both in the original Arabic and in Latin translation. In the eleventh century, Constantine Africanus, a professor at the prestigious Salerno school of medicine, translated some of Israeli's works into Latin. Many medieval Arabic biographical chronicles of physicians list him and his works.
Israeli's philosophical works exercised a considerable influence on Christian and Jewish thinkers, and a lesser degree of influence among Muslim intellectuals. In the twelfth century, a group of scholars in Toledo transmitted many Arabic works of science and philosophy into Latin. One of the translators, Gerard of Cremona, rendered Israeli's Book of Definitions and Book on the Elements into Latin. Israeli's work was quoted and paraphrased by a number of Christian thinkers including Gundissalinus, Albertus Magnus, Thomas Aquinas, Vincent de Beauvais, Bonaventura, Roger Bacon and Nicholas of Cusa. Isaac Israeli's philosophical influence on Muslim authors is slight at best. The only known quotation of Israeli's philosophy in a Muslim work occurs in Ghayat al-Hakim, a book on magic, produced in eleventh-century Spain, translated into Latin and widely circulated in the West under the title Picatrix. Although there are passages which correspond directly to Israeli's writings, the author does not cite him by name.
His influence also extened to Moses Ibn Ezra (c. 1060-1139) who quotes Isaac Israeli without attribution in his treatise The Book of the Garden, explaining the meaning of Metaphor and Literal Expression. The poet and philosopher Joseph Ibn Tzaddiq of Cordoba (d. 1149) authored a work The Microcosm containing many ideas indebted to Israeli.
As Neoplatonist philosophy waned, in addition to the Galenic medical tradition of which Israeli was a part, the appreciable influence of Isaac Israeli diminished as well.

Famous quotes containing the word influence:
“No power on earth or above the bottomless pit has such influence to terrorize and make cowards of men as the liquor power. Satan could not have fallen on a more potent instrument with which to thrall the world. Alcohol is king!”
—Eliza “Mother” Stewart (1816–c. 1908)
“I am not sure but I should betake myself in extremities to the liberal divinities of Greece, rather than to my country’s God. Jehovah, though with us he has acquired new attributes, is more absolute and unapproachable, but hardly more divine, than Jove. He is not so much of a gentleman, not so gracious and catholic, he does not exert so intimate and genial an influence on nature, as many a god of the Greeks.”
—Henry David Thoreau (1817–1862)
“The private life of one man shall be a more illustrious monarchy,—more formidable to its enemy, more sweet and serene in its influence to its friend, than any kingdom in history. For a man, rightly viewed, comprehendeth the particular natures of all men.”
—Ralph Waldo Emerson (1803–1882)
