On whose head sat this crown?

Made of solid gold approximately 2,000 years ago and discovered in 1978, it adorned the head of a Bactrian nomad king.

The crown disassembles and folds flat for easy transport.

It may be seen, along with some 230 other objects from Afghanistan's long history at the center of the network of trade routes known as the Silk Road, at the National Gallery of Art in Washington, D.C.., part of a new show entitled "Afghanistan: Hidden Treasures From the National Museum, Kabul," through September 7, 2008, following which it will travel to San Francisco, Houston and New York City.
