The Arthur M. Sackler Gallery in Washington, D.C. is currently playing host to Roads of Arabia: Archaeology and History of the Kingdom of Saudi Arabia, an "unprecedented assembly" of artifacts which tell the story of of the trade routes across the Arabian Peninsula.
From an article for ArtDaily:
Roads of Arabia examines the impact of ancient trade routes that traversed the peninsula, carrying precious frankincense and myrrh to the Mesopotamia and Greco-Roman world and allowing for a vibrant exchange of both objects and ideas. With the later rise of Islam, pilgrimage roads converged on Mecca (Makkah) and gradually replaced the well-traveled incense roads. Julian Raby, the Dame Jillian Sackler Director of the Arthur M. Sackler Gallery and the Freer Gallery of Art, describes the exhibition as “a new window onto a country whose pre-Islamic past is little known to anyone other than a handful of scholars today, and whose Islamic history is often misunderstood.”
The exhibit will be at the Sackler until February 24, 2013, after which it will travel to a number of museums around the world.
