The first, and also the most important, representative of New Platonism, is _Plotinus_. He was a pupil of Ammonius Saccas, who taught the Platonic philosophy at Alexandria in the beginning of the third century, though he left no writings behind him. Plotinus (A. D. 205-270) from his fortieth year taught philosophy at Rome. His opinions are contained in a course of hastily written and not closely connected treatises, which, after his death, were collected and published in six enneads by _Porphyry_ (who was born A. D. 233, and taught both philosophy and eloquence at Rome), his most noted disciple. From Rome and Alexandria, the New Platonism of Plotinus passed over in the fourth century to Athens, where it established itself in the Academy. In the fourth century, _Jamblichus_, a scholar of Porphyry, and in the fifth, Proclus, (412-485), were prominently distinguished among the New Platonists. With the triumph of Christianity and the consequent fall of heathenism, in the course of the sixth century, even this last bloom of Grecian philosophy faded away. The common characteristic of all the New Platonists is a tendency to mysticism, theosophy, and theurgy. The majority of them gave themselves up to magic and sorcery, and the most distinguished boasted that they were the subjects of divine inspiration and illumination, able to look into the future, and to work miracles. They professed to be hierophants as much as philosophers, and exhibited the unmistakable tendency to represent a Pagan copy of Christianity, which should be at the same time a philosophy and a universal religion. In the following sketch of New Platonism we follow mainly the track of Plotinus.
