Mbh 1.213.3

“Narada continued, ‘Bowing unto the Grandsire and saying, ‘So be it,’--the damsel walked round the celestial conclave. The illustrious Brahman was then sitting with face turned eastwards, and Mahadeva with face also towards the east, and all the celestials with faces northwards, and the Rishis with faces towards all directions. While Tilottama walked round the conclave of the celestials, Indra and the illustrious Sthanu (Mahadeva) were the only ones that succeeded in preserving their tranquillity of mind. But exceedingly desirous as Mahadeva was (of beholding Tilottama) when the damsel (in her progress round the celestial conclave) was at his side, another face like a full-blown lotus appeared on the southern side of his body. And when she was behind him, another face appeared on the west. And when the damsel was on the northern side of the great god, a fourth face appeared on the northern side of his body. Mahadeva (who was eager to behold the damsel) came also to have a thousand eyes, each large and slightly reddish, before, behind and on his flanks. And it was thus that Sthanu the great god came to have four faces, and the slayer of Vala, a thousand eyes. And as regards the mass of the celestials and the Rishis, they turned their faces towards all directions as Tilottama walked round them. Except the divine Grandsire himself, the glances of those illustrious personages, even of all of them fell upon Tilottama’s body. And when Tilottama set out (for the city of the Asuras) with the wealth of her beauty, all regarded the task as already accomplished. After Tilottama had gone away, the great god who was the First Cause of the Universe, dismissed all the celestials and the Rishis.’”
