The technique known today as primary directions is one of the most
ancient and renowned methods of astrological forecasting, and also one
of the most powerful. From classical antiquity throughout the Middle
Ages and Renaissance, and even into the twentieth century, all the great
names of western astrology have worked with primary directions. It was
the predictive technique of Dorotheus and Ptolemy, of Masha'allah and
Abu Ma'shar, of Regiomontanus and Placidus, of Morin de Villefranche and
William Lilly. To understand the Old Masters of astrology, we must
understand primary directions. Students of traditional astrology have
often been deterred by overly mathematical presentations from
approaching the important subject of directions. This comprehensive
study explains the principles of primary directions in an accessible
form, illustrating them by practical examples. It also draws on many
original source texts to outline the historical origins and development
of the technique, and shows how it has been reinterpreted and
occasionally misunderstood. A full glossary and appendices with software
reviews as well as formulae for manual calculations complement the text.
The craft of the Old Masters can still be learnt.
