I stumbled on this source, which has information on Pythagoras and numbers, music, cosmology, etc., which may be of interest to some:
https://www.rosicrucian.org/rosicrucian-digest-pythagoreans

I don’t know anything about or endorse the “Rosicrucian” organization that publishes this. I merely point it out because some of their articles on esoteric subjects (e.g., alchemy or Hermeticism) may help with research on these subjects. In particular, it looks like some articles have footnotes that point to some useful books–as a supplement to those of Dr. Farrell.
