So, a few months ago, I tried to find some reference on the medieval Chola naval vessel known as the Thirisadai - essentially the equivalent of a battleship. At this time, I posted a blog entry, requesting aid in finding these references - the request was unsuccessful, which is hardly shocking; BZPower is not exactly a community built upon a shared fondness for naval history, nor is a high proportion of the site's population comprised of historians.
Anyway, I let that project rest for a while, as I tried to find the pictures I needed. Other ideas came up, I wrote some music, bought a didgeridoo, and the idea slid to the back of my mind, resurfacing earlier today.
So, feeling lucky, I tried Google again.
This was the top result.
That's how little relevant material there is on this.
