Neoplatonic school of Plotinus. Born at Chalcis in Syria, he traced his ancestry through an ancient line of
priest-kings. A student of Porphyry, the chief disciple of Plotinus, his influential treatise Theurgia, or On the Mysteries of Egypt describes a higher magic through the agency of the gods. He sought to reconcile Plato and Aristotle, but held that Pythagoras was the supreme authority, reviving his teachings on Number as the basis of all things. He
taught that the individual soul becomes lost in matter and cannot grasp the transcendent reality with intellect alone, because the transcendent is supra-rational. He recommends theurgy, a series of rituals and operations aimed at recovering the transcendent essence by retracing the divine signatures through the layers of being. Agrippa refers frequently to Iamblichus in his Occulta
Philosophia. Iamblichus also had a strong influence on other Renaissance occultists like Ficino, Pico della Mirandola, and Giordano Bruno.

Imum Coeli (IC)
quincunx, although the classical meaning is "not in mutual aspect". Neither semisextile nor quincunx are proper aspects in the traditional sense, as a planet
is unable to "see" another in these relationships, unless it also beholds the other by virtue of being either antiscion or contra-antiscion (so not inconjunct). DeVore states that inconjunct means "dissociate" and that a planet is inconjunct when it forms no aspect and is not in parallel declination or mutual disposition to another
planet, as well as being either quincunx or semisextile.
