Strictly IBN Hauqal, a 10th century Arabian geographer. Nothing is known of his life. His work on geography, written in 977, is only a revision and extension of the Masalik ul-Mamalik of al-Istakhri, who wrote in 951. This itself was a revised edition of the Kitab ul-Ashkal or Suwar ul-Agalim of Abu Zaid ul-Balkhi, who wrote about 921. Ibn Haukal's work was published by M. J. de Goeje (Leiden, 1873). An anonymous epitome of the book was written in 1233.
