Sharpur, it never said that the elephant was carrying the palanquin. It just said she was on an elephant's back. So, obviously, the titular character rides on the back of the elephant, and the elephant is riding on the palanquin, which is carried by humans, and the humans are carried by the earth, which is carried by a giant turtle whose gender is unknown. This is why it's a palanquin and not a howdah. Obviously.
