EXETER, ENGLAND—BBC News reports that traces of a wealthy medieval city, complete with a twelfth-century mosque and Islamic burials and headstones, have been discovered at Harlaa, located in eastern Ethiopia. Pottery, glass vessel fragments, rock crystal, carnelian, glass beads, and cowry shells imported from Madagascar, the Maldives, Yemen, and China have been uncovered, along with bronze and silver Egyptian coins dating to the thirteenth century. Timothy Insoll of the University of Exeter explained that high-quality jewelry was made at the site with silver, bronze, semi-precious stones, and glass beads, using technology usually associated with jewelry made in India at that time. He thinks that jewelers from India may have been among the people who migrated to the cosmopolitan city at Harlaa. And, the mosque at the site resembles those built in Tanzania and Somaliland, which suggests that the people who lived at Harlaa also had contact with other Islamic communities in Africa. Human remains from the site are being analyzed for further information. For more, go to “Stone Towns of the Swahili Coast.”
