In Astral Worship, Dr. Hill explores the foundations of astrology and explores its influence on religions, rituals and holidays that are commonly practiced today. Astral worship or Astrolatry is the worship of stars and other heavenly bodies as deities, or the association of deities with heavenly bodies. The most common instances of this are sun gods and moon gods in polytheistic systems worldwide. Also notable is the association of the planets with deities in Babylonian, and hence in Greco-Roman religion, viz. Mercury, Venus, Mars, Jupiter and Saturn. In studying the primitive forms of religion it will be found that none of them taught anything relative to a future life, for the simple reason that their founders had no conceptions of such a state. Hence it follows that the laws they enacted were intended solely for the regulation of their social relations, and, to secure their observance, they were embodied into their sacred records and made part of their religion. One form of that most ancient worship was known as Sabaism, or Sabism. Another form of the same religion was the Ancient Judaism, as portrayed in the Old Testament.
