"The definitions of planets and signs are not random. The concepts and principles underlying these relationships are no longer a part of the curricula of life as it was for many centuries in the past, although oddly, many of these ideas still exist in our vocabulary and expressions.
Essential Dignity defines the relationship between the planets and a a zodiac sign. Each sign represents 30 degrees in the sky, yet each of these degrees is not equal. Essential Dignity describes each degree in terms of planets that have some power over each degree."

"The tradition of planetary hours stems from the ancient division of day and night, each into 12 equal portions of time. The planets then rule these portions, called hours, in a regular and unbroken order (SA, JU, MA, SU, VE, ME, MO). The cycle continues from one day to the next so that every seven days a major revolution is completed and the order of rulerships belonging to each day is fixed.

"Generally there are two methods that are used to determine significators in traditional horary and electional questions. The primary method is to look to the house rulers that relate to the question at hand. This method provides an incredible amount of detailed information because of the complexity presented by the interaction of the seven planets and the twelve houses. The twelve houses can signify all possible relationships, e.g. husband-wife, owner-personal property, and even complex relationships among various people and things, e.g.

Moon, the only constant in all kinds of horary charts, is of utmost importance in medical horary charts from the beginnings of horary astrology up to the period of her blossoming in the 17th century ...

After a lengthy discussion about definition and validity of the void of course Moon on another astrological web log, I thought it to be a good idea to have another look at William Lilly’s views on the subject and share my findings with the readers of my web log.
To show that Lilly was drawing on a long-standing tradition, I first want to quote from Dr. Dykes’ excellent new translation “Persian Nativities”

Unlike decumbitures (medical horary charts) which were chiefly promoted by the English astrologers of the 17th century like Nicholas Culpeper, Richard Saunders and William Lilly, Dorotheus’s iatromathematical charts concerning sickness are distinctive because of their specific mundane location of the sick and his physician in the chart, which could be constructed for the moment of the inception of the medical examination and establishment of diagnosis, the beginning of treatment, the moment when the sick meets the physician for the first time, the moment when the physician first heard

Most of the authorities in horary astrology stressed the importance of fulfilling certain preconditions for judging horary questions. The most famous among them, as to the number and quality of these rules included in his work and astrological theory was, certainly, Guido Bonatti (1223 – 1300) the Italian mathematician and astrologer ...

On April 1st 2009 at 13:57 PM a helicopter crashed in the North Sea, 14 miles from Peterhead. All 16 people on board were killed. The event chart very clearly shows a picture of this tragedy. The 9th house, representing the helicopter,  is ruled by Jupiter.....

"How did astrologers calculate the time, that is, the ascendants degree in ancient times, when there were no mechanisms? They used an astrolabe. It came from Greek meaning “an instrument for catching stars”. In accordance with this, any instrument used for observing  stellar positions or latitudes could be called like that."

"What differs the first katarche methods from the later horary methods, at first sight, is the lack of mundane derivations and mundane locations of a querent as well as his separation from the subject of a question (for more information about katarche you can read the article "Notion and history of Horary Astrology"). A chart always refers to a thing in a question, without the significance of houses and their derivations according to the nature of things."
