This nature of Sight having never been discovered by the ancient pretenders to Naturall Knowledge; much lesse by those that consider not things so remote (as that Knowledge is) from their present use; it was hard for men to conceive of those Images in the Fancy, and in the Sense, otherwise, than of things really without us:  Which some (because they vanish away, they know not whither, nor how,) will have to be absolutely Incorporeall, that is to say Immateriall, of Formes without Matter; Colour and Figure, without any coloured or figured Body; and that they can put on Aiery bodies (as a garment) to make them Visible when they will to our bodily Eyes; and others say, are Bodies, and living Creatures, but made of Air, or other more subtile and aethereall Matter, which is, then, when they will be seen, condensed.  But Both of them agree on one generall appellation of them, daemons. As if the Dead of whom they Dreamed, were not Inhabitants of their own Brain, but of the Air, or of Heaven, or Hell; not Phantasmes, but Ghosts; with just as much reason, as if one should say, he saw his own Ghost in a Looking-Glasse, or the Ghosts of the Stars in a River; or call the ordinary apparition of the Sun, of the quantity of about a foot, the Daemon, or Ghost of that great Sun that enlighteneth the whole visible world:  And by that means have feared them, as things of an unknown, that is, of an unlimited power to doe them good, or harme; and consequently, given occasion to the Governours of the Heathen Common-wealths to regulate this their fear, by establishing that Daemonology (in which the Poets, as Principal Priests of the Heathen Religion, were specially employed, or reverenced) to the Publique Peace, and to the Obedience of Subjects necessary thereunto; and to make some of them Good Daemons, and others Evill; the one as a Spurre to the Observance, the other, as Reines to withhold them from Violation of the Laws.

What Were The Daemons Of The Ancients What kind of things they were, to whom they attributed the name of Daemons, appeareth partly in the Genealogie of their Gods, written by Hesiod, one of the most ancient Poets of the Graecians; and partly in other Histories; of which I have observed some few before, in the 12.  Chapter of this discourse.

How That Doctrine Was Spread The Graecians, by their Colonies and Conquests, communicated their Language and Writings into Asia, Egypt, and Italy; and therein, by necessary consequence their Daemonology, or (as St. Paul calles it) “their Doctrines of Devils;” And by that meanes, the contagion was derived also to the Jewes, both of Judaea, and Alexandria, and other parts, whereinto they were dispersed.  But the name of Daemon they did not (as the Graecians) attribute to Spirits both Good, and Evill; but to the Evill onely:  And to the Good Daemons they gave the name of the Spirit of God; and esteemed those into whose bodies they entred to be Prophets.  In summe, all singularity if Good, they attributed
