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.
