Case Study 4 of 5
Napoleon Bonaparte
Born 1769-08-15, ~11:30 LMT, Ajaccio, Corsica
Day pillar 甲午 (Yang Wood on Horse) · Yang Metal Seven Killings in the hour
A Yang Wood day master in the Metal-heavy autumn month of Monkey, with Yang Metal (庚) Seven Killings hanging overhead in the hour pillar. Classical practitioners describe this configuration as “the axe over the tree.” For a lifelong military commander, the fit is sharp. Birth time is uncertain; assessment below is written to be robust to that.
The chart
Computed manually from canonical BaZi formulas (see methodology note below). Napoleon’s 1769 birth pre-dates the 1849-onward range of this site’s solar-terms table, so we cannot run the full engine interpretation. The pillars themselves — year, month, day, and hour — can still be computed by hand and verified.
The structural reading
What the chart says
Because the site’s prose interpreter does not run for pre-1850 years, the reading below is composed by hand from the same structural vocabulary the engine uses elsewhere on the site. Every claim is something that would be in the automated interpretation if the interpreter could run.
You’re a Yang Wood (甲) Day Master — the Architect, the mature oak — born in early autumn (Monkey month), when metal is taking over and the chart reads as cooling, sharpening, and consolidating. Yang Wood in the autumn month of Monkey is classically “wood being pruned by metal”: the season itself creates pressure on the day master, and the chart’s character emerges from how it responds to that pressure.
The decisive feature of this chart is the Yang Metal (庚) in the hour stem. To a Yang Wood day master, 庚 is 七杀 Seven Killings — the most confrontational of the ten gods. The Seven Killings star in the hour position reads as command-under- pressure pointed at the chart owner’s private aspirations: an inner mandate to take the fight directly rather than go around it. Paired with the 申 Monkey month branch (which also contributes Metal pressure), the structural reading of this chart is that Seven Killings is not a side feature — it is the organizing force.
The day branch 午 (Horse) is the chart’s fire element — the Yang Wood’s Output (食神 Eating God / 伤官 Hurting Officer energy in the hidden stems). Yang Wood that is being pruned by autumn metal can discharge the resulting pressure through its fire output: produce something, shape something, perform something. This is the classical “Seven Killings controlled by Eating God” dynamic — the pressure has a productive outlet, which is what separates a conqueror from someone destroyed by the same chart configuration.
Practical translation: this is a chart built for high-stakes execution under external pressure. It does not thrive in balanced, protocol-driven environments. It is at its best when there is a real target to push against, a real stake for getting it wrong, and a direct line from decision to consequence. The watch-out is that the same configuration reads as burnout-prone when the pressure loses its target: Yang Wood that cannot discharge its Output fire gets corrosively over-pruned by the autumn metal.
Chart vs. record
Biographical correlation
Five observations, each checked against the biographical record — primarily Andrew Roberts’ Napoleon: A Life(Viking, 2014), Philip Dwyer’s two-volume Napoleon: The Path to Power (Yale, 2007) and Citizen Emperor (Yale, 2013), and the Correspondance de Napoléon Ier published by the French state (1858-1869, 32 vols).
1. Yang Wood day master — the architect, the oak
What the chart says: Yang Wood (甲) — the Architect archetype. Associated with long-cycle structural work, institutional founding, infrastructure, jurisprudence, and senior engineering. Slow to move off a position once taken.
The famous military career is only half the Napoleonic record. The other half — and the half the chart reads more cleanly — is the founding of institutions. The Napoleonic Code (1804), the Banque de France (1800), the Conseil d’État, the baccalauréat, the lycée system, the Legion of Honour, the concordat with the Catholic Church. Roberts devotes a full chapter to arguing that Napoleon was primarily an administrative founder who happened to be very good at war. The Yang Wood “Architect” archetype captures the institutional-founding side of the record more than the battlefield side.
Assessment: Consistent, and a useful corrective to the pure-warrior caricature. Note that Yang Wood describes roughly one person in ten, so by itself it is not a sharp claim — the sharpness comes from the pairing with the Seven Killings configuration below.
2. Seven Killings in the hour — the blade overhead
What the chart says: Yang Metal (庚) in the hour stem is the Seven Killings ten god — command under pressure, high stakes, decisive action over protocol. Its placement in the hour pillar (private aspirations, inner mandate) reads as an internalized drive toward the fight.
Napoleon’s career is the Seven Killings archetype running at full intensity. The whiff-of-grapeshot moment at 13 Vendémiaire (October 1795), the Italian campaign of 1796-97, Marengo, Austerlitz, the seizure of power as First Consul. The record is that he spent most of his adult life either at war or between wars — by one count, he fought more than sixty battles. The Seven Killings structural reading does not predict that he would win them (see the Waterloo beat below) but it predicts the configuration of a life organized around direct confrontation rather than protocol, and on that narrower claim the record is a clean match.
Assessment: Consistent. This is the structural feature that separates this chart from a generic Yang Wood reading.
3. Horse day branch — the Output outlet
What the chart says: the day branch is 午 Horse, the Yang-Wood day master’s Eating God / Hurting Officer output element. The classical reading of a Yang Wood day master sitting on a Fire branch is that the wood discharges its pressure through its visible output, producing or performing rather than accumulating.
The volume of output is extraordinary. The Correspondance — just the letters he dictated — runs to 32 published volumes. The Code Civilbears his personal editorial hand on thousands of articles. His military dispatches from the Egyptian and Italian campaigns run longer than most generals’ careers. Whatever you make of the content, the sheer throughput of personal production is a Hurting Officer output profile running at saturation.
Assessment: Consistent. The Output outlet beat explains why this chart produces a founder rather than a person destroyed by the Seven Killings pressure.
4. Year pillar 己丑 — Yin Earth on Ox (Direct Wealth)
What the chart says: the year stem 己 (Yin Earth) to a Yang Wood day master is 正财 Direct Wealth — the classical “earned resources / accumulated assets” ten god. Its presence in the year pillar reads as a formative environment where material resources, territory, and inheritance are salient themes.
The Bonaparte family in Corsica were minor nobility with chronic financial anxiety — Roberts devotes an early chapter to the family’s legal battles over a mulberry plantation inheritance that dragged on for most of Napoleon’s childhood. Carlo Buonaparte’s death when Napoleon was 15 left the family in even more precarious circumstances, which shaped Napoleon’s early career choices (military school on a scholarship rather than the naval career he initially wanted). The Direct Wealth in the year pillar reads as the formative economic context.
Assessment:Ambiguous. The match is there but the claim is loose — “formative environment where money was a theme” is true of most ambitious lives, and we should not over-credit the reading here.
5. Late-life decline: the structural reading
What the chart says (when the classical interpretation framework runs on a Seven-Killings-in-the-hour chart): the hour pillar also reads to late life, and a Seven Killings in that position is read as a configuration that intensifies toward the end rather than resolving. A Yang Wood day master in that configuration often reads as someone whose pressure source does not lift — the blade stays over the tree until the end.
Napoleon’s late life — exile on Saint Helena from 1815 to his death in 1821 — is the archetypal “fallen conqueror under continued pressure” trajectory. He was not simply defeated at Waterloo and allowed to retire; the British kept him under active surveillance on a remote South Atlantic island for six years until he died of what contemporary pathology now reads as stomach cancer. The chart’s generic “late-life pressure does not lift” reading is a structural match.
Assessment: Ambiguous, and we should explicitly flag this one as the kind of beat where a practitioner could generate confirmation for almost any late-life difficulty. The honest version is that the chart configuration is compatible with a high-pressure late life but does not predict Saint Helena as an event.
Methodology
Napoleon’s birth data is well-attested as August 15, 1769, Ajaccio, Corsica, but the exact birth time is uncertain. Most modern biographers give somewhere between 11:00 and noon; historical biographical sources have variously cited 11:29, 11:30, and 12:00. We use 11:30 local mean time, which produces the 庚午 (Yang Metal on Horse) hour pillar shown above. A birth time anywhere between roughly 11:00 and 12:59 produces the same Horse hour branch, and the Yang Metal hour stem is stable across that range (because it follows from the day stem via the Five Rats rule).
The Napoleon case is also an edge case for this site’s engine. The precomputed solar-terms table that this site uses to identify month boundaries runs from 1849 onward, so the engine’s automated year-pillar and month-pillar computations do not run on 1769 birth dates. We computed Napoleon’s chart by hand from the canonical formulas (year pillar from (year - 4) mod 10/12, month pillar from the Five Tigers rule, day pillar from the 2000-01-07 = 甲子 anchor arithmetic, hour pillar from the Five Rats rule). The resulting pillars — 己丑 / 壬申 / 甲午 / 庚午 — match the widely-cited classical reading of his chart in Chinese-language BaZi literature.
The absence of the engine’s prose interpreter for this case is the reason the reading section above is hand-composed rather than pasted. Every claim in that section is built from the same structural vocabulary the engine uses on the other four case studies, not invented.
