Aries

20 March – 19 April, 2025

1 claim about Aries can be traced to antiquity and are still made today. Everything else on this page arrived later, and each entry says when.


When Aries actually begins

Computed from the Sun’s true ecliptic longitude for this year, not read from a fixed table. If you were born within a day of either boundary, a site using a table may put you in a different sign — and it is the table that is wrong.


What survives from antiquity

These are the only claims on this page that may honestly be introduced with “tradition holds”. Each is attested by an ancient or early-modern source and by a contemporary one.


What arrived with the popularisers

Claims that reach us through Alan Leo, Raphael and Sepharial — the Edwardian writers who turned astrology into a mass-market genre — with no ancient source behind them. These are usually the most familiar things said about Aries, and the page reference for each is below it.


What the tradition said and we stopped saying

Attested in antiquity, and repeated by no contemporary source in this corpus.

The fate the classical texts predicted

Firmicus Maternus and his contemporaries did not write character sketches. They predicted outcomes, and this is what they predicted for Aries. Every one of these has been dropped — across the whole corpus, no modern source repeats a single one.

The work

Occupations are the one part of this tradition that demonstrably reaches the present. Character claims mostly do not, and physiognomy does not at all — but the trades the classical texts assigned to Aries are still being assigned to it.

athletics — attested in antiquity and repeated today.


Rulership

The classical scheme gave every sign one of the seven visible planets. The outer planets were discovered between 1781 and 1930 and reassigned later, so where a sign has two rulers, both are real claims from different centuries. Neither is the correction of the other.

modern

none assigned

No outer planet was ever assigned to this sign. That is the answer, not a gap in the data.


Correspondences

Grouped by what kind of claim each is. Element and modality are agreed by every source in every century; the lucky numbers are agreed by almost nobody. Both appear on every astrology site in the same table, in the same type, which is how one borrows the other’s authority.

structural

Agreed by every source in every century.

classical

Classical taxonomy. Largely dropped by modern astrology.

dignity

Classical doctrine. Stable, but the outer planets are a modern addition.

mythic

The sign's image. Phrasings vary; the figure does not.

body

Melothesia — the sign's part of the body. Ancient, and not medical.

accretion

Modern accretion. Sources rarely agree with each other.

The body the old books describe

William Lilly, Raphael and Sepharial all told you what a Aries looked like. Modern astrology dropped this entirely: across the whole corpus, not one physical description is repeated by a contemporary source. It is reproduced here as what those writers said, in the seventeenth and nineteenth centuries, and for no other reason.
