Historical Figure

Vettius Valens

Also Known As Valens

Astrologers, Diviners & Fortune Tellers

Second century Hellenistic astrologer from Antioch whose nine book Anthology is the longest and most detailed working astrological treatise to survive from antiquity, drawing on over a hundred sample charts from his own case files. His techniques for dividing planetary rulership over degrees and years, still used in the reconstruction of Hellenistic method, underlie much of the Egyptian term and Arabic part material recorded here.

Facts

Disputed

Lifespan or Floruit

from 120 1

Vettius Valens gives no direct statement of his own birth year; what survives is a set of dated horoscopes within his Anthology, mostly cast between 152 and 162 CE, from which historians of ancient astrology have worked back an approximate birth around 120 CE rather than reading it from any external record.

Lifespan or Floruit

to 175 1

No external record states when Vettius Valens died. His latest securely dated horoscope falls in the 170s CE, and historians of ancient astrology cite a death somewhere around 175 CE on that basis, an estimate drawn from the latest surviving dated material rather than from any independent record of his death.

A Working Astrologer of Roman Antioch

Vettius Valens was born around 120 CE, most likely in Antioch, and was a slightly younger contemporary of Claudius Ptolemy, though the two astrologers show no sign of having known each other's work and represent two quite different traditions within Hellenistic astrology, Ptolemy the philosophically minded systematizer and Valens the practicing technician. Valens describes travelling widely through Egypt in search of specific astrological doctrines and teachers he judged worth learning from, gathering techniques into his own practice rather than working from a single inherited system.

He wrote his major work, conventionally called the Anthology, across roughly 150 to 175 CE, and it is generally judged to be substantially complete by his death around 175. Almost nothing else of his biography survives independently of what he says of himself in the text, which is itself unusually candid by the standards of ancient technical writing, including passages of personal reflection on the astrologer's craft and its difficulties. Nothing is known of any formal training he received, and unlike several later Hellenistic astrologers he claims no divine or legendary transmission for his method, presenting it instead as a working technician's accumulated craft, refined through practice and correction over a working lifetime rather than received from any authoritative source.

The Anthology and Hellenistic Technique

The Anthology, nine books in Greek, is the longest surviving astrological treatise from antiquity and the single richest source for how Hellenistic astrology was actually practiced rather than only theorized. Valens included more than a hundred sample nativities drawn from his own case files, complete with his working calculations, making the text an unusually direct window onto real professional method rather than an abstract exposition.

Modern reconstruction of Hellenistic technique, including the systems of Arabic Parts and Egyptian planetary terms that the atlas describes across its astrological content, draws heavily on Valens alongside Ptolemy and the fragmentary earlier sources both of them preserve. The standard critical edition is David Pingree's 1986 Teubner text; Valens has no ancient biography beyond his own book, so essentially everything known of him as a person, rather than as a technical author, is inferred from what he chose to say about his own training and travels within it. Where Ptolemy's Tetrabiblos aimed to give astrology a philosophical justification within a broader natural science, Valens made no such argument and simply assumed the discipline's validity, a difference in temperament that later historians of astrology have used to characterize the whole distinction between astrology's theoretical and its practical wings in the ancient world.
