《论衡·卷十一·说日篇》
如果是死的，长期在太阳与月亮里，要么烧焦了，要么腐朽了；如果是活的，日蚀的时候太阳会完全看不见，月亮在每月末经常会消失，那么乌鸦、兔子、癞蛤蟆又都在什么地方呢？
生也？如死，久在日月，燋枯腐朽。如生，日蚀时既，月晦常尽，乌、兔、蟾蜍皆何在？
If they are dead, they will be burned or rotted if they have been in the sun and moon for a long time. If they are alive, the sun will be completely invisible during the solar eclipse, and the moon will often disappear at the end of each month, so where are the crows, rabbits and toads again?
