Virgo 23.3° · born September 16, 1887
Birth time unknown

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

The day, read honestly

Five of the ten placements whose signs are settled fall in mutable signs, the widest weighting the unknown hour leaves certain. The mutable signs sit where one season is already becoming the next — the scheme’s translators.

Positions at 12:00 civil time in 9th arrondissement of Paris—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

Virgo, but precisely: 23.3°, third decan, 20°–30°, under Venus in the triplicity scheme. The tradition kept these divisions because thirty degrees is a long street.

Closer to the ground

Closer in, Mercury stands at 28.2° Virgo; Venus stands at 1.4° Libra; Mars stands at 12.9° Leo. The tradition reads a mind that trusts the measured and the checked from Mercury, taste led by wit and proportion from Venus, drive that ignites on contact from Mars.

The angles that hold

Nothing in the geometry sits closer than Mars and Uranus: 1.2° from an exact sextile. A sextile pays out only on effort; the scheme calls it opportunity rather than gift. Behind it, Venus trine Neptune at 1.4°, and Venus sextile Saturn at 1.8° — both still well inside the orbs this site uses. Each angle here was measured at every hour of the civil day and held; whatever the missing clock said, this geometry was in it.

Figures in the geometry

The Moon stands apart from every major angle the day held — the tradition reads an unaspected planet as a voice that speaks on its own schedule, unmodulated by the rest of the chart.

The classical map

Of the seven planets the classical scheme judges, three sit in a sign it has an opinion about. Mercury in Virgo at 28.2° is in exaltation — the tradition’s honoured-guest placement, working at its best; Venus in Libra at 1.4° is in domicile — the planet in its own sign, running on home rules; Saturn in Leo at 3.2° is in detriment — the planet opposite its home, working against the grain. None of these labels is a verdict on a person; they describe how a function is situated, nothing more.

The shape of the whole

Tallied where the signs are certain — 10 placements whose signs hold for the whole day — the chart gives air 4, earth 3, fire 2, water 1, and mutable 5, fixed 3, cardinal 2 across the modes. Air weights a chart toward language and pattern — the impulse to name a thing before deciding how to feel about it. Venus, Neptune 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 Virgo for the whole of that day at the birthplace, covering 14.9° 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 7.9°.
