Estakhri

Abul Qasim Ubaidullah ibn Abdullah ibn Khurdad-bih (aka Estakhri, Persian: استخری, i.e. from the city of Estakhr) was a medieval Persian geographer in the 9th century.

It was Estakhri who created the earliest known account of windmills. His works included "Al-masaalik al-mamaalik" (المسالك الممالك) and "Suwar al-Aqaaleem" (صور الاقاليم).

He also wrote the "General Survey of Roads and Kingdoms" in the mid-9th century. It was the first non-East Asian geographical work to make a reference to Korea.
