First, a bit of context. When and where were these hero stones made? They're a particular fixture of the Deccan - the yellow bit in the map here - from roughly 600 CE onwards till well into the 1300s. This is also, not coincidentally, the period when the Deccan began to see a systematic trend towards complex agrarian polities. As you can imagine, that's great for ambitious warlords.

Now for the interesting bit: what is a hero stone? Simply put, as Deccan states grew more and more militarised, they found that they had more and more military "heroes" to celebrate. But hero stones don't just commemorate wars: you'll see memorials to dead hunters, cattle-rustlers, ascetics, devoted wives. They can be crudely-shaped rocks made by local artisans or elegant gnomons cut by master sculptors in cosmopolitan cities.
@AKanisetti I read somewhere that there are a few of these stones lying around in Bangalore city
@AKanisetti one for sure is there in Yelahanka old Vishnu temple.
@ppmanik plenty in the Bangalore Museum too, and we have a civil society group (Inscription Stones of Bangalore) that aims to preserve them too!
@ppmanik @AKanisetti where exactly is this? Will visit next time I m in Bangalore.
@silverlightgal @ppmanik the Museum? It's in Central Bangalore, not far from Cubbon Park.
