These are just a few of my favourite sites related to Traditional Astrology, Alchemy, Magick, Qabalah, Hermetica and Astronomy. These are sites I've chosen as a short list of what I consider the best. See the list of Classical Astrologer Net Ring members also. They are all highly recommended.
Skyscript is Deborah Houlding's site, devoted entirely to Classical Astrology. There is an impressive collection of articles and interviews. Horary classes are available. This site is highly recommended!
The Lost Horoscope X-Files is the place where you will find some of the most obscure, bizarre, mysterious and misunderstood astrological procedures investigated..... Highly recommended! Be sure to also visit Curtis Manwaring's astrology software page.
Spira Solaris is an excellent site, featuring well-written scholarly articles on Hermetica, Qabalah, Neo-Platonism and related topics, of great interest to Classical Astrologers.
World Astrology is the on-line home of Dorothy J. Kovachhome and Anton Grigoryev. This site is primarily devoted to Mundane Astrology, in the spirit of the European medieval and Renaissance astrological tradition. World Astrology features excellent articles on the subject, mostly by Anton Grigoryev
Project Hindsight The main focus of Project Hindsight has been the restoration of the astrology of the Hellenistic period (300 B.C.E. to about 600 C.E.). This is the astrology that developed in Egypt and the surrounding Mediterranean area after the Alexandrian conquest and through the Roman period. It is the primary source for all later Western astrology. We believe that we are the first to have restored this ancient discipline to its original form.
The John Dee Publication Project. The major purpose of this site is to distribute primary-source materials relevant to the "Enochian" work of John Dee and Edward Kelly, particularly reconstructions of Dee's Spirit Diaries, from the original manuscripts.
