Horary astrology is a very ancient predictive technique.
It is believed that horary astrology is the most ancient ever predictive technique as it is not required to have the birth time of the consultant.
English astrologer William Lilly is considered to be the father of modern horary astrology.
The precise moment when the consultant is asking the question is used by the astrologer to build the horary chart.
The horary chart will be used by the astrologer who will identify the houses involved in the questions, their rulers and the relationship between them.
