chronocrator timing
Firmicus frames lunar time-lord periods around fluctuation, bodily vulnerability, and changing fortune, with stronger danger when the lunar condition is harsher.

docs-only
- A Mars-in-Cancer example belongs to unfavorable-ruler example material about exile and self-inflicted death, not to a parent-abandonment aphorism.
- A Moon/Saturn condition is the source-backed parent-abandonment and disrupted-nurture claim in this reviewed batch.
- A public-reputation lane can support project-launch goals when visibility is the actual topic: Choices emphasizes the eleventh house, Jupiter, the Sun in the tenth, Moon applications by supportive aspects, and received significators for good name and manifest completion.
- Abu Ma'shar derives several house topics by analogy to planetary indications: the fourth from solar father/origin language, the fifth from Venus and Jupiter themes of children and pleasure, the sixth from Mercury's hiddenness and instability as illness/service, the seventh from lunar meetings and marriage, the eighth from Saturn and death, and the ninth from Jupiterian religion and travel.
- Abu Ma'shar uses lunar visibility relative to solar distance in an exaltation argument, including a general Moon-visibility boundary around twelve degrees while preserving latitude and contextual caveats.
- Abu Ma'shar's Hermes marriage-time lot uses the Sun-to-Moon relation from the Ascendant by day and night, and its timing testimony is read when marriage is already indicated in the nativity.
- Bonatti frames the root of elections as adapting the Moon, the Sun, the planet naturally signifying the intended matter, and the sign fitting the matter, keeping the chosen sign free from malefic impediment when possible.
- Bonatti separates electional judgment across the person, the undertaking, its end, the Moon, Fortune, and relevant rulers; Fortune can help the matter even when the Ascendant lord and Moon do not fully protect the person.
- Choices gives Al-Butayn as the second mansion from 12 deg 51 min 26 sec Aries to 25 deg 42 min 52 sec Aries, with favorable indications for sowing and journeys and cautions around marriage, slaves, ships, and captives by reference to the Al-Nath page.
- Choices gives Al-Nath as the first mansion from the beginning of Aries to 12 deg 51 min 26 sec Aries, with electional indications covering medicines, pasture, journeys, animals, arms, planting, grooming, clothes, marriage, slaves, associations, capture, and theft questions.
- Choices gives Al-Thurayya as the third mansion from 25 deg 42 min 52 sec Aries to 8 deg 34 min 18 sec Taurus, with favorable indications for trade and vengeance and a middling indication for travel; its table identifies the Pleiades as the likely star group.
- Davison treats the marriage chart as a valid chart in its own right that can be compared with both partners' nativities and read by houses, transits, and directions; difficult angular malefics and Uranus involvement with the luminaries, Venus, or the seventh house are framed as cautions.
- Davison treats the public or legal wedding ceremony as the operative beginning of the marriage chart and recommends choosing a time with supportive marriage-chart factors, including favorable luminary, Venus, Mars, Jupiter, Ascendant, seventh-house, Moon, and Fortune conditions, while avoiding difficult Moon and malefic testimony.
- De Quindecim provides a fifteen-star electional or magical corpus with Moon and angle framing that should remain separate from general chart-overlay fixed-star mechanics.
- Dorotheus gives the Wedding lot for men as the Sun-to-Moon arc projected from Venus.
- Dorotheus gives the Wedding lot for women as the same Sun-to-Moon arc projected from Mars.
- Firmicus distinguishes a Moon condition in which Venus configured to a waning Moon and Mars configured to a waxing Moon are treated as adverse phase-sensitive witnesses.
- Firmicus gives a narrow eighth-house Moon condition that is qualified by nocturnal nativity and Jupiter testimony, keeping the judgment tied to house, luminary, and benefic support.
- Harness states the nakshatras divide the zodiac into 27 equal segments of 13 deg 20 min each and that each lunar mansion is subdivided into four padas of 3 deg 20 min.
- Hephaistio preserves a narrow lunar phase and sign aphorism for which parent is indicated as predeceasing, with Pisces, masculine signs, and feminine signs distinguished by lunar condition.
- In Bonatti's partnership and money-contract election, the Moon is kept free from malefic impediment and preferably received by trine or sextile; hard aspects indicate quarrel in the eventual separation, and fallback priorities include the Ascendant ruler, Moon, second, fourth, eleventh, their rulers, and Fortune.
- Liber Hermetis gives the female Wedding or Marriage variant by projecting the Moon/Sun relation from Mars, using Moon minus Sun by day and Sun minus Moon by night.
- Liber Hermetis gives the male Wedding or Marriage variant by projecting the Moon/Sun relation from Venus, using Moon minus Sun by day and Sun minus Moon by night.
- Paulus describes the planetary-hour sequence as a planet going about for the day while successive planets execute the hours in Chaldean order, beginning with the day lord and repeating through day and night.
- Paulus gives a Moon application and separation procedure that considers same-sign degree order, adjacent-sign degree relation within thirty degrees, activity tiers at three, seven, fifteen, and thirty degrees, and aspect-side applications.
- Paulus gives a thirteenfold twelfth-part procedure for stars, pivots, and lots, then distinguishes benefic and malefic twelfth-part contacts to lights, Mercury, pivots, Fortune, Spirit, Necessity, and the prenatal lunation.
- Project-launch has a direct foundation-lane witness when the action has a real first act: Bonatti treats the first stone, timber, or column as the operative beginning, and then adapts Ascendant, Moon, Fortune, matter significator, and hour lord as available.
- Purchase elections have direct topic witnesses: buying-for-profit and common-purchase pages emphasize adapting the Moon, Mercury, the second and eleventh houses, Fortune, benefic support, and avoiding Mars and the Tail.
- Purchase is a topic family, not one universal page: estate, house, land, and similar purchases use specific Ascendant, Moon, fourth-house, Fortune, Saturn, benefic, and malefic-avoidance considerations.
- Sahl defines transfer of light as a lighter planet separating from one significator and applying to another, carrying the first planet's nature to the second and indicating mediation through go-betweens in the example.
- Sahl varies lunar impediment by lunar phase, malefic, sign gender, and aspect: Mars weighs more against a waxing/hot Moon, Saturn more against a waning/cold Moon, with sign and sect-like conditions modifying severity.
- Skymates describes composite chart construction as averaging the two birthcharts, using midpoints between corresponding planets such as Sun, Moon, and Mercury.
- The Choices war-election passage keeps Fortune and its ruler away from enemy houses and places them with the Ascendant or second when possible, avoids impediment to the Ascendant and its ruler, makes Mars, Mercury, the Moon, and the Moon's lord fit for the war matter, and notes Mars natal testimony in victory judgments.
- The new-love preset has direct support only as a love/friendship-seeking lane: the witnesses emphasize the Moon, Venus, the eleventh house and its ruler, reception, Jupiter support, and freedom from impediment.
- Valens treats Mars square the Moon in a day nativity, when configured from the left and in another's degrees or signs, as an adverse condition tied to maternal affliction, rank reduction, travel, and military hardship; lack of Ascendant testimony worsens the outcome, opposition is more severe, and Mars or Moon in their own signs changes the judgment.
- Valens treats Venus square the Moon as potentially favorable when condition is supportive, but reverses the judgment toward instability and disrepute when dignity, sect, or degree conditions are contrary; opposition is worse under those same adverse conditions.
