The Javanese myth of Tantu Pagelaran explains the origin of Java island. Batara Guru (Shiva) ordered the gods Brahma and Vishnu to fill Java island with human beings. However at that time Java island was floating freely on the ocean. To make the island stay still, the gods decided to nail it on the earth by moving part of Mahameru in Jambudvipa (India) and attaching it upon Java. Vishnu transformed into a giant turtle and carried the Meru upon his back, while the god Brahma transformed into a giant naga serpent and wrapped his body around the mountain and giant turtle's back, so the Meru mountain could be transported safely. The mountain fragments scattered upon Java created the volcanoes and mountainous regions spanned from west to east. The main part of the Meru mountain attached to the eastern part of Java. Later the gods cut off a small tip to make Mount Pawitra (Mount Penanggungan,) while the main part of Meru mountain became Semeru volcano, the abode of Lord Shiva.
