There are many cases of the applications in the conventions. As the nowadays conventions regarding the aspects in astrology have
been established on the elementary convention of conjunction formed by two planets such as disclosed by L. KOLISCO,
however, we can not find the description of conjunction aspect in the books of Ptolemy in the First Century released. The concept of
aspect applied to the art of astrology was first described in a book by John Kepler in the early part of the Seventeenth Century.
Therefore, our nowadays definition on the aspects in astrology could be different from the knowledge of the ancient people.
As we have no way to verify the aspect in astrology scientifically, the experiment made by KOLISKO has remain in the convention
agreed but not in the theory verified. Although we can find each definition made on each aspect respectively, however, the
conventions for aspects
in astrology would be kept in a good standing.
The conventions on definition for the roles of planets on the other hand will be much weaker than that of the aspects.
The roles of planets are defined on the basis of thought delivered from the convention of zodiac signs that were delivered
from the ancient convention of twelve set of constellation settled. These conventions have been supported by the confidences of
many astrologers participated. As the description made by Ptolemy have suggested, the roles of a planet could be modified
greatly by the other planet joined. A planet may become beneficial to human and yet the same planet could become maleficent.
Many other conventions in astrology such as that of the house division will also be delivered from the zodiac convention. Therefore
these are also unstable to be modified by another study proposed.
As so many kinds of rules are accumulated in one horoscope, we can select any one rule at the beginning.
We must be careful enough to recognize the line of thought placed in the construction of a rule.
Any rule has its own history and its own logicality studied. For instance, the rule of emotional pattern or
Fire Earth Air and Water triangle is defined without any reference to the trine aspect. Therefore, we must not
alter the definition of trine aspect formed in the planet which tenanted sign does not fit the emotional pattern.
Further more, we must not set the
ORB for the sign boundary.
A proper tool in a right application for a nice result. No one will enjoy a dish with all spices mixed.
