PHASIS is a new complete, user-friendly, classical astrology software with unique features. It can be used both by beginners and by professional astrologers and it is currently used in the school of Cielo e Terra, where the first version of this project was realized at the end of the nineties. The software is reserved to members of the cultural association Cielo e Terra.

The program, highly customizable, has a Ptolemaic orientation, with particular attention to visual phenomena and mundane methods. Data concerning heavenly bodies invisible to the naked eye are missing, except for some special modules where Uranus, Neptune and Pluto are showed if required by the user.

Planetary positions are calculated according Jean Meeus’ algorithms, whose accuracy is perfect for every astrological purpose and for every date throughout the history of astrology.

Mac Intel OS X 10.4 or higher
