ابن حوقل
The Arab geographer Ibn Hawqal visited Spain and the Maghreb between 947 and 951 A.D. According to the account in his "Kitab Surat al-Ard" completed in around 988 AD, Sijilmasa grew in economic power due to shifting trade routes. At one time trade between Egypt and the Ghana Empire took a direct route across the desert, but because of the harsh conditions, this route was abandoned. Instead caravans passed through the Maghreb to Sijilmasa and then headed south across the Sahara. Sijilmasa's economic wealth is evidenced by Ibn Hawqal's story about a bill issued to a trader in Awdaghust for forty-two thousand dinars from another merchant based out of Sijilmasa. Ibn Hawqal explains that he has never heard of such a large sum of money in all of his travels. Not only was Ibn Hawqal impressed with the volume of trade with the Maghrib and Egypt, Al-Masudi noted gold from Sudan was minted here.
