Abu Ishaq Ibrahim ibn Muhammad al-Farisi al Istakhri (aka Estakhri, Persian: استخری, i.e. from the Iranian city of Estakhr, b. - d. 957 AD [346AH]) was a medieval geographer in medieval Islam who wrote in Arabic in the 10th century.
It was Estakhri who created the earliest known account of windmills. His Arabic language works included masalik al-mamalik (مسالك الممالك, "Traditions of Countries") and Suwar al-Aqaaleem ( صور الاقاليم, "Shapes of the Climes").
