Leo 29.1° · born August 22, 1862
Birth time unknown

Birth date sourced. Birth time unknown.Moon sign undetermined. The Moon crossed from Cancer into Leo during that day. Everything below uses only what the complete civil day settles.

The day, read honestly

The Sun stands at 29.1° Leo, in domicile — the planet in its own sign, running on home rules. Of everything the chart can be read for without a birth time, that is the loudest single fact in it.

Positions at 12:00 civil time in Saint-Germain-en-Laye—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

The Sun's position resolves to 29.1° Leo — deep enough in the third decan (20°–30°) that Mars, its traditional sub-ruler, colours the reading.

Closer to the ground

Closer in, Mercury stands at 2.2° Virgo; Venus stands at 1.4° Leo; Mars stands at 18.4° Aries. The tradition reads thought with its feet on the ground from Mercury, attraction declared rather than implied from Venus, effort spent in bursts and openings from Mars.

The angles that hold

The tightest geometry in the chart puts Mars a sixth of the circle apart from Uranus, 1.8° off exact. A sextile pays out only on effort; the scheme calls it opportunity rather than gift. Behind it, Venus sextile Jupiter at 1.9°, and Venus trine Neptune at 2.0° — both still well inside the orbs this site uses. The unknown hour cannot unmake any of this: every aspect named survived all twenty-five samples of the day.

Figures in the geometry

The Moon makes no major aspect that survives the day; the old reading gives such a planet autonomy — it acts alone, sometimes loudly.

The classical map

The oldest layer of the scheme — seven planets, four conditions — flags four placements in this chart. The Sun in Leo at 29.1° is in domicile — the planet in its own sign, running on home rules; Mercury in Virgo at 2.2° is in exaltation — the tradition’s honoured-guest placement, working at its best; Mars in Aries at 18.4° is in domicile; Jupiter in Virgo at 29.4° is in detriment — the planet opposite its home, working against the grain. Dignity is a statement about conditions, not about worth.

The shape of the whole

Balance, counted honestly across the 9 placements whose signs hold for the whole day: elements fire 4, earth 4, air 1; modalities mutable 4, fixed 3, cardinal 2. A fire emphasis is read as appetite for the first move, with information gathered by doing rather than before doing. No settled placement falls in water — an absence the tradition treats as information, not as a defect. Neptune and Pluto were retrograde — apparent retreat against the stars, which the old reading takes as a function working from the inside first.

The Moon is genuinely open

The Moon crossed from Cancer into Leo during that day at the birthplace, travelling 12.3° between one midnight and the next. Which of the two it was depends entirely on the hour, and the hour is not recorded. Rather than pick the likelier half, the reading leaves the Moon open.
