One of the most basic magical techniques is the tuning of one's working space to match the influence or spirit being conjured. As I discuss in Mastering the Mystical Heptarchy, modern magicians often accomplish this by relying on the Greater Rituals of the Pentagram and Hexagram or similar ceremonial forms, but during the Renaissance a system of hours was used that was believed to follow the natural flow of spiritual currents in the universe. As a modern magician my general practice is to use both, which seems to augment the effectiveness of my rites quite nicely.
The most well-known aspect of this system is that of the planetary days and hours based on the Chaldean Order, which breaks each 24-hour period from sunrise to sunrise into twelve day and twelve night hours. These hours vary in length depending on the season, with night hours longer during the winter and day hours longer during the summer. The system works quite well for planetary magick - the hour was generally considered to be more important than the day, so when timing an operation for a particular day the most auspicious time could be selected. However, it would be convenient to extend this system for work with the signs of the Zodiac and classical elements along authentic Renaissance grounds. From my introductory studies of traditional astrology I believe that I may have worked out just such a method.
