Slowly the world’s museums are beginning to unlock their doors.

In 1324, Mansā Mūsā, the Muslim ruler of the empire of Māli and the richest man in the history of the world, set out on a pilgrimage to Mecca. His route took him along the central trans-Saharan caravan route to Cairo, where he joined the Hajj caravan to Mecca. He travelled with a retinue of eight thousand men and one hundred camels, each carrying three hundred pounds of gold.
