Horary astrology is a branch of  traditional astrology in which an astrologer attempts to answer a question using the chart for the time and place at which the question was understood by the astrologer.

This divinatory technique involves identifying the querent (the person who asks the question) and the quesited (what is being asked about) and deciding if there's a connection between them. In order to do so, the astrologer relies on the use of specific rules and principles, such as collection of light, reception, radicality of the question, etc.

In this introductory course, each of these principles will be viewed in detail;  covers the fundamental concepts of this technique, and each point is further explained with example charts. 

It  is based mainly on Christian Astrology, the text written by William Lilly in the 17th century, but references to other authors such as Sahl, Abu Mashar, Anthony Louis, Deborah Houlding, Lee Lehman, etc. are also included.
