Natal Chart

NAY-tuhl chart

Definition

A natal chart — also called a birth chart, horoscope, geniture, or nativity — is a map of the sky calculated for the exact moment and place of your birth. It records where the Sun, Moon, planets, and key points sat within the zodiac signs and houses, the rising degree (the Ascendant), and the angles, or aspects, the bodies make to one another. The Greek genesis (γένεσις) and the Latin nativitas and genitura all name the chart itself.

In Tradition

In Hellenistic, Arabic-Persian, and modern Western practice, the natal chart is the foundation of natal astrology — genethlialogy, the astrology of birth. It is read as the configuration through which a life unfolds: the planets and points carry the birth significations, while transits, progressions, and time-lord cycles play out against this fixed frame. Holden treats the chart as the prime indicator of destiny, with the rising sign (horoskopos) forming the first house in the Greek system.

In Practice

Astrologers cast the chart from the date, time, and place of birth, using an ephemeris and a house-system method. A standard reading works through: (1) sect — whether you were born by day or by night; (2) the Sun and Moon by sign and house; (3) the Ascendant and its ruling planet; (4) the planets by sign, house, dignity, and aspect; (5) the lots, such as Fortune and Spirit; and (6) the topics of each house, read through their rulers. Timing techniques — profections, zodiacal releasing, primary directions, transits, secondary progressions, solar returns — all use the natal chart as their fixed reference. The recorded time matters: it shifts the Ascendant, Midheaven, house cusps, and Moon position, and rectification techniques refine an uncertain birth time against documented life events.

Historical Origin

The earliest surviving Hellenistic horoscopes include literary chart-attestations around 100 BCE and, per Rochberg, the Babylonian-tradition cuneiform horoscope of Anu-bēlšunu (-249 BCE). The Hellenistic genre is fully developed by Dorotheus (1st c. CE), Manilius, Ptolemy's *Tetrabiblos*, and Valens' *Anthology*, then transmitted to Arabic-Persian and medieval Latin authors and codified for English horary by Lilly's *Christian Astrology* (1647).
