This temple was literaly discovered a few years back.
Digging to lay foundations for a building in the middle of a metropolis, they found a temple that has been buried under sand for ages. It has been restored.
This is the tomb of Vyasaraja who was the guru teacher/advisor of Krishnadevaraya of the Vijayanagara Empire. It is near Hampi. I have just got Vyasayogicharite a champu kavya by Somanatha Kavi and am planning to read it. I am also looking for travelogues and other catalogs of those times. One that I have found is the pair Paes and Nuniz. I will post further after I have details.
P.S. I took this photograph myself. Anyone is free to use it in their articles on Vyasathirtha.
