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.
