Firmament is a name for the sky or the heavens, generally used in the context of Christianity, Judaism and Islam. In the Vulgate, the word firmamentum is used, which means in classical Latin a strengthening or support. For Jewish and Christian astronomers familiar with Greek astronomy, the firmament was the eighth sphere carrying the fixed stars, which surrounded the seven spheres of the planets in the geocentric model.
