The philosophical and mathematical commentaries of Proclus on the first book of Euclid's elements (Vol. 1 of 2) : $b To which are added, A history of the restoration of Platonic theology, by the latter Platonists: And a translation from the Greek of Proclus's Theological elements
Plato · en
his philosophic life, having found him such an auditor and successor
as he had for a long time sought for; and one who was adapted for the
reception of a multitude of disciplines, and divine dogmata.
In a shorter space, therefore, than two years, he read, together
with Syrianus, all the works of Aristotle, i. e. his logic, ethics,
politics, physics, and theological science. But being sufficiently
instructed in these, as in certain[55] proteleia, and small mysteries,
Syrianus led him to the sacred discipline of Plato, and this by an
orderly progression, and not[56] according to the oracle, with a
transcendent foot. And he was careful that he might survey with him
true mysteries, with the eyes of his soul, free from material darkness,
and with a speculation of intellect refined and pure. Hence Proclus
was employed night and day in vigilant energies, and in writing
compendiously what he had heard, employing his own judgment in the
selection and order. And in consequence of this unwearied assiduity,
he made so great a progress in a short time, that by then he was
twenty-eight years of age, he composed a multitude of works; and among
the rest his very learned and elegant commentaries on the Timæus. But
from an institution of this kind, his manners also received a greater
ornament, since as he advanced in science he accumulated virtue.
In the original κατὰ τὸ λόγιον, which I wonder Fabricius should
translate, _quod aiunt_, as it is usual with the Platonists, to
cite the Zoroastrian oracles exactly in these words, instances of which
may be found in Proclus on Plato’s theology; and the very words prove
themselves to be a part of an oracle, when attentively considered.]
