Pref., p. iii Ascribed by Ouseley in his translation to Muḥammad ibn Ḥauḳal and by Sprenger in the catalogue of his manuscripts (no. 1) to Aḥmad ibn Sahl (Abü Zaid) al-Balkhī. In 921 al-Balkhī wrote a geographical work in which the maps were the important part. Ca. 951, al-Iṣṭakhrī wrote a revision of al-Balkhī's work, commonly known as the "Kitāb al-aḳāiīm," in which he extended the description of places. A second revision of al-Balkhī's work was made ca. 977 by Ibn Ḥauḳal. cf. M.
