 Gradually, the whole Organon was made available in Arabic translation (the Arabic tradition was unique in treating Aristotle’s Rhetoric and Poetics as part of logic, unlike later traditions in medieval logic. The first more important Arabic logician was Ishâq al-Kindî (d. 870), who wrote a short overview of the whole of the Organon. After him, more and more substantial works were produced. Abû Nasr Alfarabi (d. 950) made the first original contributions, writing a series of commentaries on Aristotle, although only his commentary on De interpretatione has survived. Avicenna seems to have held his work in very high esteem. By far the most important logician in the Arabic tradition, however, was Ibn Sînâ (d. 1037) or Avicenna, as he was known in the Latin West.
