C.U.R.A. The International Astrology Research Center

Digital International Astrology Library (DIAL)

I have placed these two websites of Patrice Guinard at the head of this section because of their importance to astrology in general and to the study of ancient, medieval and early modern astrology in particular. The C.U.R.A. website is a leading forum for astrological research as well as philosophical speculation. And the D.I.A.L. website, which is attached to the C.U.R.A. website, represents an incredible job of locating astrological texts on the websites of major European libraries. While a knowledge of Latin and/or other ancient languages is helpful, there are also a number of texts in English and other modern languages. No serious student in this field can afford to ignore this website.
