Mbh 8.33.1b

' Saying unto them, 'Let it be so,' that god ascended to heaven. Those Asuras then, filled with joy at having obtained those boons and having settled it among themselves about the construction of the three cities, selected for the purpose the great Asura Maya, the celestial artificer, knowing no fatigue or decay, and worshipped by all the Daityas and Danavas. Then Maya, of great intelligence, by the aid of his own ascetic merit, constructed three cities, one of which was of gold, another of silver, and the third of black iron. The golden city was set in heaven, the silver city in the welkin, and the iron city was set on the Earth, all in such a way as to revolve in a circle, O lord of Earth. Each of those cities measured a hundred yojanas in breadth and a hundred in length. And they consisted of houses and mansions and lofty walls and porches. And though teeming with lordly palaces close to each other, yet the streets were wide and spacious. And they were adorned with diverse mansions and gate-ways. Each of those cities, again, O monarch, had a separate king. The beautiful city of gold belonged to the illustrious Tarakaksha: the silver city to Kamalaksha, and the iron one to Vidyunmalin. Those three Daitya kings, soon assailing the three worlds with their energy, continued to dwell and reign, and began to say, 'Who is he called the Creator?' Unto those foremost of Danavas having no heroes equal to them, came from every side millions upon millions, of proud and flesh-eating Danavas who had before been defeated by the celestials, and who now settled in the three cities, desirous of great prosperity. Unto all of them thus united, Maya became the supplier of every thing they wanted. Relying upon him, all of them resided there, in perfect fearlessness. Whoever amongst those residing in the triple city wished for any object in his heart had his wish fulfilled by Maya aided by the latter's powers of illusion. Tarakaksha had a heroic and mighty son named Hari.
