The four elephants....
In my mind I always pictured the elephants standing trunk to tail on the Great A'Tuin's back and slowly walking turnwise. One rotation would take a year, and that's what gives the disc it's seasons and year. But in fan art, the elephants are depicted as standing still and facing outwards. Have I got it wrong all these years? Are the elephant's positions mentioned in any of Terry's works? If they are facing out and not moving, how did the fifth elephant stumble and fall off the disc? If they are stationary, then how does the disc rotate?
