John Venn's Birth Chart
Sun in Leo · Moon in Leo ≈
John Venn, FRS, FSA was an English mathematician, logician and philosopher noted for introducing Venn diagrams, which are used in logic, set theory, probability, statistics, and computer science. In 1866, Venn published The Logic of Chance, a groundbreaking book which espoused the frequency theory of probability, arguing that probability should be determined by how often something is forecast to occur as opposed to "educated" assumptions. Venn then further developed George Boole's theories in the 1881 work Symbolic Logic, where he highlighted what would become known as Venn diagrams. Wikipedia
Sun in Leo
11°33′Your essence asks to shine from the heart, with authenticity: to create, express and give warmth to those you love. You are contagiously vital. You need to inhabit your own centre with pride and give your creativity an outlet.
Moon in Leo
1°17′Your heart needs to be seen, needs warmth and room to show itself as it is: loyalty and sincere recognition are your emotional nourishment. You feel magnanimously and need your affections to affirm your true self.

Birth time not documented
The Ascendant changes sign every two hours, and no verified birth time is recorded for John Venn, so this chart doesn't set it. Their planets by sign, however, remain reliable.
Section II · The map
Their natal wheel
The sky on the day they were born. The outer ring is the twelve signs; the lines across the centre, the aspects between planets. Without a birth time, houses and the Ascendant aren't drawn.
Section III · The detail
Planets and aspects
The exact numbers behind the drawing. Each table expands one layer of the wheel.
John Venn's placements
We compute the placements for the day of birth. Without the exact time the Ascendant and houses can't be fixed, but each planet's sign is reliable.

Beyond the planets
Three keys beyond the ten classical planets, which astrology reads as axes of the chart. All four angles need your birth time.
The wounded healer: a small icy body between Saturn and Uranus. It marks the wound that, once moved through, teaches.
Not a body but a point of the Moon's orbit. It marks the direction of your growth.
The Black Moon: a mathematical point tied to the untamed and what refuses to submit.
John Venn's aspects
Each aspect is an angle between two planets; it defines how they speak to each other. Aspects to the Moon are approximate: they depend on the exact birth time.
Elements and modalities
How their energy is split across the four elements and the three modalities.
Section IV · The signature
The signature of their sky
The whole at a glance: how the planets are spread, and the accents that set the overall tone of the chart.
Locomotive
They cover two thirds of the sky, leaving one third empty: a constant drive toward that gap.
Their energy concentrates in the element of Fire and the Fixed modality.
Saturn is the most connected planet in their chart: 8 aspects tie it to the rest.
Three or more planets together in Leo: a strongly marked focus of energy in that area.
Three planets in trine forming a triangle: a talent that flows almost effortlessly.
