And when the chaītya hall turned towards the west, the crocodile-dragon of Varuna, the ruler of the cosmic ocean into which the sun sinks every evening, was carved at the springing of the arch,[1] and a lion's or dragon's mask, with gaping mouth as if swallowing the whole arch, was carved at the crown.

And certainly the rules of the Sangha did not tolerate any traffic with the despised Vedic fire-worshippers. They only prescribed the patterns which were lawful for the bhikkus to use as decorations, and gave them a metaphorical interpretation in accordance with the Buddha's teaching.
The carved entrance to one of the rock-cut hermitages in Bihar, near Gāyā, known as the Lomas Rishi cave, is an exact reproduction of the roof-end from which the sun-window is derived. The hermitage was one of those which were dedicated by Asoka for the use of a certain sect known as the Ājivikas, and dates from about 257 b.c.
