William Blake was a Cancer Rising with Moon placed in domicile in the 12th house of hidden enemies and evil spirits. Four aspects are made by this strong Ascendant ruler. The first is to creative Venus in opposition. The second is a sesqui-quadrate to Mercury ruler of 3rd house, ruler of writing and mental thought. The third aspect is a bi-quintile to Sun second house ruler placed in the 5th house of creativity and children.
The Sun Moon longitudinal connection in Blake´s chart is compounded by a contra-parallel emphasising the importance in expressing the houses involved. 1st house ruler Moon in 12th channels his self and identity into the search for all things hidden and mysterious. If there was something hidden and unknown to society then Moon in own sign and therefore having the highest essential dignity would indicate that it would be seen, perceived and felt in a most emotional, and psychic way. The Moon-Sun aspect connects the first house (reason for being and living) with the 2nd house (house of value and income) with the 12th house of the unconscious and the 5th of creativity. And primarily, William Blake made his livelihood from the most creative of crafts involving poetry, drawing, writing and the most skillful of engraving, the most notable demonstration of this Biquintile aspect.
The second important planet that Cancer Moon contacts in this chart is Venus, placed in the 6th house of work and daily business in Capricorn. The fact that Venus rules 4th and 11th houses is testament to the fact that his home was his workshop and a place of meeting with the people who Blake had political and social intercourse with.
Mercury in this chart is important. Mercury ruler of 3rd and 12th houses aspects to both Moon within the 12th that gives the ability to write about the 12th house knowledge, but also in aspect to Mars ruler of the Midheaven and Blake´s eventual life´s work. This Mercury, however, is conjoined with a Sagittarius Jupiter, imparting a wisdom, knowledge and awareness from its rulership over the 6th and 9th houses.
The final rulership to be considered in Blake´s chart must be 7th ruler Saturn aspecting both Mars in opposition and Moon through another Biquintile. And to note, his wife was greatly involved in his work being also contra-parallel to MC ruler Mars and energetically linked to him (Biquintile Moon).
Descendant ruler Saturn also rules 8th house and is placed exactly on the 8th cusp. Catherine Boucher his wife would have been a huge support to him and possibly mystical or psychic with regard to having domicile over the 8th. She was also probably a most humane and dignified woman with Aquarius Saturn, the sign of rational understanding and possibly most solid and loyal placements.
The most powerful planet in this chart despite combustion, is Jupiter; placed in the fifth house, and lord over Mars, Mercury, North Node and Sun. It is no surprise therefore that his art and creation (5th house) is inspired by spiritual fire and Religious and Mystical knowledge, with Jupiter having direct rulership of the 9th house of dreams and higher knowledge.
Fixed Stars Bungula (our closest neighbour Alpha Centaury) and Antares, the Royal Star Archangel Oriel and Watcher of the West would have been closely conjunct Blake´s Mercury and Sun. These stars are both bright and strong influences. Mercury with Alpha Centaury is described as pertaining to occult knowledge and philosophy, and the star which denotes the Heart of the Scorpion of the nature of Mars Jupiter and Mercury would have emphasised the nature of the mystery involved.
