FirmicusA vocation and talent reading from your birth chart with Firmicus

What is career astrology?

Career (vocational) astrology reads the birth chart in terms of talent, way of working and the role you take on in society. A chart does not give you a job title; it shows where you are naturally strong, what kind of setting you work well in and which periods are open to change.

The Midheaven and the 10th house

The Midheaven (MC, Medium Coeli) is the highest point of the sky at the moment of birth; it is the start of the 10th house and describes how the world sees you and how you want to be recognised. The MC sign sets the tone of the career, and the planet that rules it shows which area of life feeds the talent. That is why the birth time matters: the MC changes sign roughly every two hours.

The Midheaven extension chain

A common technique in modern career astrology is to follow the ruler of the MC: from the sign the ruler occupies you move on to that sign's ruler, and the chain continues until it stops at a planet in its own sign, in a loop or at a mutual reception. The planet and house where the chain gathers are where the vocational message is most concentrated. (Sign rulers)

Quality of action

In the classical tradition Ptolemy reads vocation as the "quality of action" from Mercury, Venus and Mars: the planet that rises before the Sun and the one near the Midheaven show the source of talent. Mercury stands for speech, calculation and trade; Venus for beauty, harmony and the arts; Mars for technique, courage and work with fire and iron. When two of them combine, the blend is read.

Earning, daily work and career

The 2nd house describes how you earn and what you value, the 6th the daily work setting and routine, the 10th career and standing. When the rulers of these three houses sit in one another's houses or in harmonious aspect, these areas flow easily; tense aspects show a balance that needs tuning but also gives drive.

Timing

Transits of Jupiter, Saturn, Uranus, Neptune and Pluto to the MC and its ruler point to periods of opportunity, restructuring or change of direction in a career. For a detailed timeline see the forecast advisor Abu Ma'shar; for the whole chart, try Ptolemy's birth chart reading.

Who was Firmicus Maternus?

Iulius Firmicus Maternus was a Roman author writing in Latin in the 4th century CE, under the emperor Constantine and his sons. By his own account he was Sicilian, and for a time he worked as an advocate in the law courts. His years of birth and death are unknown.

His best-known work is the eight-book Mathesis, written around 334–337 and dedicated to Lollianus Mavortius, governor of Campania. The Mathesis is one of the most complete Latin astrology books to survive from antiquity; it sets out at length the positions of the planets in signs and houses, the angles of the birth chart and what they mean for a person's life, occupation and character. It was first printed in Venice by Aldus Manutius in 1499.

Around 346, now writing as a Christian, he dedicated De errore profanarum religionum (On the error of profane religions), a polemic against pagan cults, to the emperors Constantius II and Constans. Most scholars accept that both works are by the same author and that the Mathesis was written before this change; the exact date of his conversion is unknown. The lunar crater Firmicus is named after him.
