Cielo e Terra (Sky and Earth) is a non-profit association, founded in 1999 with the intention to promote a serious and thorough study of the ancient science of the stars.

By the term classical astrology, we mean the doctrinal corpus including the period from first centuries before the Christian age until the first half of the XVII century, in particular referring to Ptolemy and his major commentators' works.

The Association considers important the techniques of foresighting of the ancient astrologers, the technical terms of this art, organizes courses and lessons of classical astrology, and intends to promote the exchange of knowledge between scholars in Italy and abroad.
