The Ptolemaen Musica

An often neglected small treatise, conventionally entitled The Ptolemaean 'Musica' (apparently dated to the Late Antiquity), is translated into the Russian for the first time. The work is a compilation of various sources, which include the Aristoxenian rhythmics, the Neopythagorean numerology and harmonics as well as the Ptolemaean geocentric astrology. According to its author the planetary cycles in their unity are closely related to the musical proportions. This approach further allows correlating the planetary rhythms with the musical rhythmics.
