Libra 5.6° · born September 29, 1901
Birth time unknown

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

The day, read honestly

Across the nine placements whose signs are settled, cardinal leads with five. Cardinal weight is read as initiative: the instinct to be the reason something began.

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

Where the Sun actually stood

5.6° of Libra is the Sun's exact seat — first decan, 0°–10°, sub-ruled by Venus in the old triplicity scheme. The degree is the address; the sign is only the street.

Closer to the ground

For the fast movers, Mercury was at 27.7° Libra, Venus was at 14.3° Scorpio, Mars was at 19.4° Scorpio. Read together: thought that travels by comparison; attraction that works by atmosphere; effort that surges when it matters.

The angles that hold

The day's firmest angle joins the Sun and Jupiter — a square holding at 1.0°. Nothing in a square flows; everything in it works. The old texts kept squares for the charts they respected. Behind it, Jupiter opposition Neptune at 3.1°, and Mercury trine Neptune at 3.8° — 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.

The standing structure

Jupiter opposes Neptune while both square the Sun. A t-square aims the whole axis at its apex planet; the tradition reads it as the chart’s standing assignment. 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, five placements stand out. The Sun in Libra at 5.6° is in fall — the tradition’s uphill placement, strength earned rather than given; Venus in Scorpio at 14.3° is in detriment — the planet opposite its home, working against the grain; Mars in Scorpio at 19.4° is in domicile — the planet in its own sign, running on home rules; Jupiter in Capricorn at 4.6° is in fall; Saturn in Capricorn at 10.0° is in domicile. None of this ranks anyone; dignity describes footing, and footing can be worked with.

The shape of the whole

Counting only the 9 placements whose signs hold for the whole day, the chart runs 3 air, 3 water, 2 earth, 1 fire by element and 5 cardinal, 2 fixed, 2 mutable by modality. Air runs on comparison and connection — the pattern noticed first, the feeling filed second. Pluto was 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 Aries into Taurus during that day at the birthplace, travelling 14.9° 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.
