Virgo 7.5° · born August 30, 1797
Birth time unknown

Birth date sourced. Birth time unknown.The Moon remained in Sagittarius throughout that civil day. Everything below uses only what the complete civil day settles.

The day, read honestly

Four of the ten placements whose signs are settled stand in Virgo — the Sun, Mercury, Mars and Uranus. The placements whose signs could change with an unknown hour are not counted. A cluster that size becomes the section the rest of the chart plays around.

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

Where the Sun actually stood

7.5° of Virgo is the Sun's exact seat — first decan, 0°–10°, sub-ruled by Mercury in the old triplicity scheme. The degree is the address; the sign is only the street.

The personal registers

Day to day the chart speaks through Mercury in Virgo (28.0°), Venus in Libra (2.8°), Mars in Virgo (0.8°): thought with its feet on the ground, attraction that begins as conversation, effort banked steadily until it tells.

The angles that hold

The Sun and Neptune hold the closest angle here — a sextile, 0.9° wide. A sextile pays out only on effort; the scheme calls it opportunity rather than gift. Behind it, Saturn trine Neptune at 1.1°, and Mars opposition Pluto at 1.6° — 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.

What the angles build

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 three placements in this chart. Mercury in Virgo at 28.0° is in exaltation — the tradition’s honoured-guest placement, working at its best; Venus in Libra at 2.8° is in domicile — the planet in its own sign, running on home rules; Saturn in Cancer at 9.5° 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

The certain ground: 10 placements whose signs hold for the whole day, dividing 4 earth, 2 fire, 2 air, 2 water by element and 5 mutable, 3 cardinal, 2 fixed by mode. Jupiter and Pluto were retrograde — apparent backward motion from where the Earth sits, which the tradition reads as a function turned inward before it is turned out.

The Moon, and how far it can move

The Moon stayed in Sagittarius for the whole of that day at the birthplace, covering 12.1° between midnight and midnight. The missing clock moves the Moon by half a sign at most here, and the boundary was never close. At the noon reference it stands at 22.2°.
