So requisite is the use of Astrology to the Arts of Divination, as it were the Key that opens the door of all their Mysteries.
Heinrich Cornelius AgrippaNatural Magick therefore is that, which considering well the strength and force of Natural and Celestial beings, and with great curiosity labouring to discover their affections, produces into open Act the hidden and concealed powers of Nature.
Heinrich Cornelius AgrippaMagic is a faculty of wonderful virtue, full of most high mysteries, containing the most profound contemplation of most secret things, together with the nature, power, quality, substance and virtues thereof, as also the knowledge of whole Nature, and it doth instruct us concerning the differing and agreement of things amongst themselves, whence it produceth its wonderful effects, by uniting the virtues of things through the application of them one to the other.
Heinrich Cornelius AgrippaAll these delusions of Divination have their root and foundation from Astrology. For whether the lineaments of the body, countenance, or hand be inspected, whether dream or vision be seen, whether marking of entrails or mad inspiration be consulted, there must be a Celestial Figure first erected, by the means of whole indications, together with the conjectures of Signs and Similitudes, they endeavour to find out the truth of what is desired.
Heinrich Cornelius AgrippaI confess that Magic teacheth many superfluous things, and curious prodigies for ostentation; leave them as empty things, yet be not ignorant of their causes. But those things which are for the profit of men -- for the turning away of evil events, for the destroying of sorceries, for the curing of diseases, for the exterminating of phantasms, for the preserving of life, honor, or fortune -- may be done without offense to God or injury to religion, because they are, as profitable, so necessary.
