All about the Discworld
The "world-elephants" are mythical animals which appear in Hindu cosmology. The Amarakosha (5th century) lists the names of eight male elephants bearing the world (along with eight unnamed female elephants). The names listed are Airavata, Pundarika, Vamana, Kumunda, Anjana, Pushpa-danta, Sarva-bhauma, and Supratika. The names of four elephants supporting the earth from the four directions are given in the Ramayana : Viroopaaksha (east), Mahaapadma (south), Saumanasa (west), Bhadra (north).
