Title
Hapanta Platōnos meth hypomnēmatōn Proklou eis ton Timaion, kai ta Politika, thēsaurou tēs palaias philosophias megistou
Description
This volume contains the second Greek edition of the Platonic corpus, edited by Johannes Oporinus and Simon Grynaeus; the text is based upon the Aldine edition of 1513. The book was printed at Basel by Joannes Valderum in March 1534. In addition to the text of Platonic works, the edition contains commentaries by Proclus on the Timaeus and the Republic. Notes in Latin, Greek, and French have been written throughout the volume. These notes often comment upon different readings of the text, citing sources including Cicero, Calcidius, and Proclus; printing errors are also pointed out and corrected*. The pages displayed are from the section of the Timaeus in which the composition of the world’s body and soul is described. The chart on the right page relates to Proclus’ commentary on the Timaeus 35b-36b, where Plato states that the Demiurge created harmonious divisions of the world soul. Conforming to Pythagorean numerology, Plato’s conception of harmony, music, and geometry depended upon integer multiples and divisions:
2 x 1 = 2 2 x 2 = 4 2 x 4 = 8
3 x 1 = 3 3 x 3 = 9 3 x 9 = 27
These integer relationships form musical intervals.
2:1 = octave
3:1 = double octave
3:2 = fifth
Ancient Greek studies in acoustics produced mathematical arrangements of proportions in order to establish their scale. Thus, the proportions represented in the second horizontal line are:
432:384 = 9:8 (wholetone)
486:432 = 9:8 (wholetone)
512:486 = 256:243 (leimma, i.e. halftone)
576:512 = 9:8 (wholetone)
648:576 = 9:8 (wholetone)
729:648 = 9:8 (wholetone)
These intervals form a musical scale. The subsequent lines in the chart give similar proportions in greater multiples.
