Control over emerald mines in Egypt shifted from the Roman Empire to the Blemmyes during the Early Middle Ages, archaeologists have found. These are the results from research carried out in 2020 and 2021 by an international team of archaeologists led by Joan Oller Guzmán of the Universitat Autònoma de Barcelona.
Digs were carried out at the Roman site of Sikait, a set of buildings surrounding Roman Egypt’s emerald mines, located in Egypt’s Eastern Desert. The area was known in Antiquity as “Mons Smaragdus”, given that it was the only place within the Roman Empire where emeralds could be found.
