When a third planet faster than either of two significator is separating from an aspect with the first significator and is applying to an aspect with the second significator. The third planet transfers the light between significators. If these significators might not otherwise apply to an aspect, the third planet acts like an intermediary. Horary astrology. According to Lilly, translation of light occurs when two significators, having separated from a trine, sextile, or conjunction, are reunited by a planet faster than either of them which leaves an aspect with one and forms an aspect with the second. The planet from which the third and faster planet separates must occupy a place in the zodiac where the latter is dignified by rulership, triplicity, or term. In the diagram below, Venus translates the light from Jupiter to Mars, Mars having separated from an aspect with Jupiter, which is in the sign Venus rules. Translation in a horary chart signifies that the matter represented by the significators comes to pass though the planets form no aspect.
