Sagittarius 19.2° · born December 11, 1863
Birth time unknown

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

The day, read honestly

Four of the nine placements whose signs are settled fall in fixed signs, the widest weighting the unknown hour leaves certain. The fixed signs are the scheme’s ballast — mid-season, fully committed, expensive to turn.

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

Where the Sun actually stood

At noon on that date the Sun stood at 19.2° Sagittarius, inside the second decan (10°–20°), whose traditional sub-ruler is Mars. The decan is the older, finer division — it is what the sign looks like once you stop rounding it to thirty degrees.

Closer to the ground

For the fast movers, Mercury was at 24.6° Sagittarius, Venus was at 2.4° Scorpio, Mars was at 26.3° Scorpio. Read together: thought that arrives already in motion; attraction that works by atmosphere; effort that surges when it matters.

The angles that hold

Closest first: Mercury to Uranus, a opposition with 1.4° of slack. An opposition puts two needs on opposite shores of the same water. Neither drowns; neither gets the whole beach. Behind it, the Sun sextile Saturn at 3.0°, and the Sun opposition Uranus at 4.0° — 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

Read against the old dignities, four placements stand out. Mercury in Sagittarius at 24.6° is in detriment — the planet opposite its home, working against the grain; Venus in Scorpio at 2.4° is in detriment; Mars in Scorpio at 26.3° is in domicile — the planet in its own sign, running on home rules; Saturn in Libra at 16.2° is in exaltation — the tradition’s honoured-guest placement, working at its best. The table describes circumstance rather than quality — a planet in detriment is inconvenienced, not diminished.

The shape of the whole

Counting only the 9 placements whose signs hold for the whole day, the chart runs 3 fire, 3 water, 2 air, 1 earth by element and 4 fixed, 3 mutable, 2 cardinal by modality. A fire-weighted chart runs hot at the start line — initiative is its native language. Uranus, 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 Sagittarius into Capricorn during that day at the birthplace, travelling 14.8° between one midnight and the next. A birth time would settle it in a second; there isn’t one. So the Moon stays unnamed here — the alternative is a guess wearing the clothes of a fact.
