Apuleius, On the God of Socrates 6
1.
Gods are not the only superhuman beings who feature in real-world religions. A whole host of lesser beings crowd the space between humans and the heavens. The ancient Greeks called these beings daemones. From this our own word "demon" derives, yet, unlike the demons of the New Testament or the saints' lives, these spirits were not unambiguously maleficent.
Fickle as the air of which they were made, the daemones were sometimes good, sometimes evil. As Apuleius, the author of the most famous ancient fantasy-story, the Metamorphosis, tells us in his theological treatise On the God of Socrates, they served as the gods' intermediaries with mankind, transmitting prophetic dreams and inspiring seers. They could even direct the lives of individual persons: each man had his guardian daemon, and the philosopher Socrates himself felt (so Plato's Apology tells us) that he was directed through life by the inspiration of his daimonion, the titular "god" of Apuleius' treatise.
The gulf between gods and men was not impermeable, therefore, and not everything that received worship was a "god" in a strict sense, that is, a good and powerful being fully removed from the corruption of the world. The gods' underlings had their place, and deserved their due, just like the emperors' subordinates, or the patrons--the bosses, or perhaps the dons, as it were--to whom the average Roman looked for support in time of need.
