Texte intégral

1The author describes an Arabic treatise concerning the geometrical problem of determining the visible horizon for an observer of a certain height on the surface of the earth. This treatise has been attributed to the Iranian mystic poet Bābā Afḍal al-Dīn al-Kāšī (13th century). The author compares the contents of the treatise with remarks about the same problem contained in the two extant letters that the famous 15th-century scholar Ġiyāṯ al-Dīn Jamšīd al-Kāšī wrote to his father, as well as with information in another work by the latter scholar. On the basis of similarities in the treatment and the parameters he concludes that the Arabic treatise was in fact written by Ġiyāṯ al-Dīn. The article includes a critical edition and English translation of the treatise.
