Anima Astrologiae or A Guide for Astrologers by William Lilly 1676

The 76th is to Consider, From what Planet the Moon separates, and which she is joined to; he whom she separates from signifies what hath been, the other what is to come, as we have said. And therefore, if she separates from an Infortune, and applies to a Fortune, the worst is past; and what hitherto has been had, will end happily to the Querent’s content. But if she separates from a Fortune, and goes to an Infortune, understand the contrary, the thing was good in the beginning, but proves naught in the end. If from a Fortune to a Fortune, is was and is good, and will have a laudable end. If from an Infortune to an Infortune, it will be an ugly conclusion. [This Consideration is in the doctrine of ‘Translation.’ Translation of the light and nature of a planet when a planet separates from one that is slower than itself, and overtakes another either by conjunction or aspect. In horary astrology it is a good omen if the aspect be good; but if by an evil aspect, it is said to denote evil or difficulty when the event comes to pass. Thus, if a question of marriage a light planet translates the light of the lord of the 7th House to the Lord of the Ascendant, it is a good omen, if it be by good aspect, and denotes that a person answering the description of such translating planet will bring the parties together, and they will be eventually happy. If it be by evil aspect, it will be done either from ill motives or will be attended with much trouble and disappointment.]
