Aries 11.0° · born March 31, 1732
Birth time unknown

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

The day, read honestly

The Sun stands at 11.0° Aries, in exaltation — the tradition’s honoured-guest placement, working at its best. 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 Rohrau—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

At the noon reference the Sun sits 11.0° into Aries — the second decan, which the old scheme hands to the Sun. Same sign, different decan, different chart.

Closer to the ground

The personal planets sit Mercury at 1.1° Aries, Venus at 15.4° Taurus, Mars at 5.0° Sagittarius. Mercury in a fire sign reads as thought that arrives already in motion; Venus in a earth sign reads as attraction that grows by reliability; Mars in a fire sign reads as effort spent in bursts and openings.

The angles that hold

Closest first: Mars to Jupiter, a sextile with 0.8° of slack. A sixth of the circle is close enough for cooperation and far enough that it stays optional. Behind it, the Sun trine Uranus at 0.8°, and Neptune trine Pluto at 1.8° — 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 three placements in this chart. The Sun in Aries at 11.0° is in exaltation — the tradition’s honoured-guest placement, working at its best; Venus in Taurus at 15.4° is in domicile — the planet in its own sign, running on home rules; Saturn in Aries at 7.3° is in fall — the tradition’s uphill placement, strength earned rather than given. 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 5 fire, 4 air, 1 earth by element and 5 cardinal, 4 mutable, 1 fixed by mode. Fire leads with ignition: the first move made early, and certainty arriving ahead of the evidence. No settled placement falls in water — an absence the tradition treats as information, not as a defect. Jupiter, Uranus and Pluto were retrograde — apparent retreat against the stars, which the old reading takes as a function working from the inside first.

The Moon, and how far it can move

The Moon stayed in Gemini for the whole of that day at the birthplace, covering 13.2° between midnight and midnight. The sign survives the missing hour; the degree does not, and is given as a reference rather than a fact. At the noon reference it stands at 19.5°.
