Uzbekistan: The Sogdian Molla Kurgan ossuary (a container for human bones); the lower section shows...

The Sogdians established a trading network across the 2400 kilometres (1500 miles) from Sogdiana to China. In fact, the Sogdians turned their energies to trade so thoroughly that the Saka (Scythians) of the Kingdom of Khotan called all merchants suli, 'Sogdian', whatever their culture or ethnicity. An ossuary is a chest, box, building, well, or site made to serve as the final resting place of human skeletal remains. They are frequently used where burial space is scarce. A body is first buried in a temporary grave, then after some years the skeletal remains are removed and placed in an ossuary. The greatly reduced space taken up by an ossuary means that it is possible to store the remains of many more people in a single tomb than if the original coffins were left as is.
