Cancer 17.7° · born July 10, 1871
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

Four of the nine placements whose signs are settled stand in Cancer — the Sun, Mercury, Jupiter 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 16th arrondissement of Paris—a reference instant, not a birth time. No houses, rising sign, angles, or sect were computed.

Where the Sun actually stood

The Sun's position resolves to 17.7° Cancer — deep enough in the second decan (10°–20°) that Mars, its traditional sub-ruler, colours the reading.

The fast planets

For the fast movers, Mercury was at 16.5° Cancer, Venus was at 3.1° Virgo, Mars was at 11.2° Libra. Read together: thought steeped in tone and memory; attraction that grows by reliability; effort aimed through strategy and words.

The angles that hold

The tightest geometry in the chart puts Mars at right angles from Jupiter, 0.6° off exact. A square is friction that produces motion — the aspect the tradition credits with building capability precisely by refusing to be comfortable. Behind it, the Sun conjunction Mercury at 1.2°, and the Sun sextile Pluto at 1.9° — both still well inside the orbs this site uses. All of it stands whatever the hour was: each angle was tested from midnight to midnight before it was written down.

Figures in the geometry

Jupiter opposes Saturn while both square Mars. Two squares braced against one opposition make a t-square — the chart’s working end, where pressure keeps finding the same outlet. 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 dignity table, which predates the outer planets and only ever spoke for seven, marks four placements here. Venus in Virgo at 3.1° is in fall — the tradition’s uphill placement, strength earned rather than given; Mars in Libra at 11.2° is in detriment — the planet opposite its home, working against the grain; Jupiter in Cancer at 10.6° is in exaltation — the tradition’s honoured-guest placement, working at its best; Saturn in Capricorn at 5.7° is in domicile — the planet in its own sign, running on home rules. Dignity is a statement about conditions, not about worth.

The shape of the whole

The certain ground: 9 placements whose signs hold for the whole day, dividing 4 water, 3 earth, 1 air, 1 fire by element and 7 cardinal, 1 mutable, 1 fixed by mode. A water emphasis reads as porousness: the room is registered whole, long before it is analysed in parts. Saturn was retrograde — motion that reverses only from this vantage point, and which the old reading treats as delay used for revision.

The Moon is genuinely open

The Moon crossed from Aries into Taurus during that day at the birthplace, travelling 12.2° 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.
