I have been asked whether I have actually seen beads from Borobudur:

A few years ago, when I frequented Southeast Asia, I was able to encourage Dr. James Langton and Jamey Allen to join me on a trip to Bali and Java. We visited bead makers in east Java and the Borobudur World Heritage Site.

Thousands of beads are carved on hundreds of human sculptures at this colossal relic. Yet, in fact, I am not familiar with beads which came from Borobudur's Sailendra Dynasty, 778-842 AD.

Stefany's faceted bicones could be compared in size and shape with beads typically from Jember. Initially kidding about chocolate, we may have stumbled onto an important question: Are there any surviving beads which can be identified as Sailendra?

While this mysterious temple is an excellent example of one of the major sources of Indonesia"s cultural legacy, little history from this period is known -which was 300 years before Angkor Wat. However, we can be certain that Borobudur had a huge workforce of sculptors and artists.
