Originally, that carving was not of Indradevi; it was of a princess (cousin of Jayavarman VII). The altar was set up to pay homage to her, because her ashes were placed there after her death. But, later on it was replaced by the carving of Indradevi at the end of Jayavarman VII's reign. To this very day, people have erroneously believed it to be so. The sloppiness and how asymmetrical the stone blocks are fitted together is a clear indication. Also, the local legends tells a different story of how it came to be, and its significance. I'm really interested in knowing more about her. Is there any possibility you could get more inquiries pertaining to her, through the local legends there? I would greatly appreciate it. 🌞
