Where Numerology Came From
The history of numerology is a path from the sacred numbers of Mesopotamia to the angel numbers of the twenty-first century. Numerology is the belief in a mystical or esoteric connection between numbers and a person's character and destiny, as well as the practice of interpreting the numerical value of letters in words and names (gematria). When applied to names, it is a form of onomancy — divination by names. Numerology is often linked with astrology.
There is no unequivocal answer to the question "who invented numerology": modern numerology is a product of the twentieth century, the word "numerology" is recorded in English from approximately 1907, and before that the practice was called arithmancy (from Greek arithmos — "number" and manteia — "divination"; arithmancy is known from the 1570s). The roots, however, are ancient: sacred numbers of Mesopotamia, the Pythagorean teaching, and Kabbalistic gematria. The marketing claim of "numerology that is thousands of years old" mixes two layers — ancient number symbolism and modern practice; in the article they are distinguished, and interpretations are presented as "according to tradition."
Sacred Numbers of the Ancient World
Mesopotamia: Seven and Ziggurats
The earliest traces of number symbolism lead to Mesopotamia. Seven had mystico-religious significance as early as the twenty-second century BCE. According to one hypothesis, this is connected with the Sumerian sexagesimal numeral system: when dividing by 7, the first result was an infinite repeating decimal (Muroi, 2014) — seven "broke" the familiar counting order.
In ancient Babylon, seven was an astral number: it was connected with the idea of seven planets, which is why seven-tiered ziggurats were built. Astronomers of the Neo-Babylonian Empire (from 626 BCE) divided the week into seven days.
Assyria: The Number of the King's Name
The practice of assigning numerical values to words and names is also very ancient. An Assyrian inscription of the eighth century BCE, executed by order of King Sargon II, reports that the wall of his new capital Khorsabad was built to a length of 16,283 cubits "in accordance with the numerical value of the name" of the king (Luckenbill, 1927). Caveat: calling this practice "gematria" is a modern interpretation; the term itself is attested in the Jewish tradition only from the second century CE.
Egypt: Legend Instead of Facts
Egypt in this story is more of a backdrop. According to late ancient tradition (Herodotus, Diogenes Laertius), Pythagoras received the teaching of the transmigration of souls from the Egyptians; legend has it that he studied under the priests in Thebes under Pharaoh Amasis II. This is a legend, not an established fact: there is no evidence of an Egyptian letter-number system in verified sources, so the claim of "Egyptian numerology" is not reproduced here.
The School of Pythagoras (6th Century BCE)
Pythagoras and the Pythagorean League
The ancient Greek philosopher Pythagoras of Samos (circa 570 – circa 495 BCE) was born on the island of Samos; around 530 BCE he moved to Croton (Southern Italy), where he founded the Pythagorean League, which, by tradition, kept the teaching secret and led a communal ascetic way of life. He died in Croton or Metapontum.
No authentic writings of Pythagoras have survived, and almost nothing reliable is known about his life: the main sources are late ancient biographies by Diogenes Laertius, Porphyry, and Iamblichus, full of legends. The most reliable attribution to Pythagoras is the teaching of metempsychosis — the transmigration of souls; tradition also attributes to him the "harmony of the spheres" (musica universalis) — the idea of the musical-numerical harmony of celestial bodies. The teaching of the early Pythagoreans is known from the testimony of Plato and Aristotle and from fragments of Philolaus, who is considered the first Pythagorean writer.
The League went through a turbulent history: it flourished under the tyrant Polycrates (circa 530 BCE); after Croton's victory over Sybaris (circa 510 BCE), the Pythagoreans came into conflict with supporters of democracy, their houses were burned, and in the mid-fifth century BCE the League was destroyed — by tradition, members of the League were killed in the meeting house. By the fourth century BCE, the teaching was absorbed by Platonism.
"All Is Number" and the Tetractys
The school's central thesis — "all is number" — is attributed to the school as a whole on the testimony of Aristotle (Met. I, 5): the Pythagoreans "recognized that the elements of number are the elements of all things and that the whole heavens are harmony and number," and saw in numbers themselves analogies — "justice," "soul or mind," "good fortune." This is an attribution to the school by Aristotle; according to a number of researchers, specific Pythagoreans may not have had such a teaching.
The school's sacred symbol — the tetractys: numbers from 1 to 4 laid out as dots in the form of an equilateral triangle; their sum — the sacred ten, "perfection and fullness of being." The Great Russian Encyclopedia describes the tetractys as the "musical-numerical structure of the cosmos"; Iamblichus in Life of Pythagoras reports that students swore by the tetractys — the surviving oath is "I swear by him who transmitted the tetractys." The ten was considered the "ideal number," and people tried not to gather in groups of more than ten.
Pythagoras is credited with the discovery of the mathematical nature of musical intervals: the octave — 1:2, the fifth — 2:3, the fourth — 3:4.
Numbers received stable symbolic meanings: 1 — the monad; 2 — the dyad, matter; 3 — the "ideal number," the smallest to have a beginning, middle, and end, from three the sacred symbol of Apollo — the triangle — is built; odd numbers were considered male, even female; 5 (2 + 3) — the number of marriage; 4 — justice; 7 — the "right moment" (kairos), the number of virginity, associated with Athena.
Isopsephy, the Miletan System, and Divination by Name
According to Aristotle, the Pythagorean tradition practiced isopsephy — the Greek predecessor of Jewish gematria: letters were assigned numbers, and the sum of the values of a word was interpreted symbolically. The practice of designating letters by numbers developed in the Greek city of Miletus (the Miletan system); early examples are in vase painting of the sixth century BCE, and in general use the system was already during the time of Alexander the Great (336–323 BCE); it was officially adopted in Egypt under Ptolemy II Philadelphus (284–246 BCE).
A special form of Pythagorean mysticism is onomatomancy: the sums of the numerical values of the letters of a name were used in interpretation. There was also a reduction technique — pythmenes ("roots"): the values of the letters of a word were reduced to a single number 1–9; modern numerological reduction descends from this technique.
In early Pythagoreanism, a distinction was made between mathematici ("learners") and acousmatici ("listeners"); the latter were traditionally considered the keepers of the "old faith" — mysticism and number symbolism, while the mathematici developed the school's scientific program.
Caveat: Pythagoras's School and Modern "Pythagorean Numerology"
Modern "Pythagorean numerology" should not be confused with ancient Pythagoreanism — this is directly warned by English Wikipedia. The thesis "all is number" is attested for the school as a whole by Aristotle; according to Walter Burkert, Pythagoras was a charismatic religious teacher, and the "philosophy of numbers" was an innovation of Philolaus (circa 470–385 BCE), while Pythagoras himself did not work with numbers; this is one interpretation. The modern letter tables 1–9 and reduction are a twentieth-century reconstruction, not ancient practice. Pythagoras's biography and the Pythagorean square are described on separate pages of the site.
Antiquity and the Middle Ages: Gematria and the Kabbalah
Gematria and Jewish Letter-Numbers
Gematria — a method of Jewish exegesis in which the meaning of words is analyzed through the numerical values of letters: words with equal sums are considered symbolically connected. The term appears in rabbinic literature from the second century CE and was first recorded in the 29th of the 32 hermeneutical rules of Eliezer ben Jose HaGelili (circa 200 CE). Example: the numerical value of the name "Eliezer" equals 318, which reconciles the biblical mention of 318 servants of Abraham (Gen. 14:14) with the legend of a single servant.
Jewish letter-numbers — 22 letters with values from 1 to 400, zero absent — entered usage by the second century BCE (first evidence — 78 BCE); the designations of numbers were borrowed from the Greeks, from Miletus. Analogues of gematria exist in other traditions: abjad in Arabic, akshara-sankhya in Devanagari, isopsephy in Greek and Cyrillic; the latter persisted in Greek-Orthodox circles even after the Edict of Thessalonica (380 CE).
The Kabbalah and the Sefer Yetzirah
Gematria is especially widely used in the Kabbalah — a mystical current of Judaism, formed in the twelfth century and spreading in the sixteenth century. Foundational texts — the Sefer Yetzirah ("Book of Creation"), the Bahir, and the Zohar (first printed edition — Mantua, 1558). The authorship of the Sefer Yetzirah is traditionally attributed to Abraham; the dating is disputed: from the second century BCE (Reitzenstein) to the sixth century CE (Kaplan), the widespread version is around 300 CE. In the teaching of the book, the influence of Neopythagoreanism is seen — this is how the ancient tradition continued to live in the Kabbalah.
Neopythagoreanism
Neopythagoreanism — the revival of Pythagorean teaching — is attributed to the first century BCE – first century CE (Eudorus, Philo): according to Philostratus, Apollonius of Tyana imitated Pythagoras, and Nicomachus developed Pythagorean numerology and music theory.
The Renaissance: Reuchlin and Agrippa
Johann Reuchlin: The Tetractys and the Tetragrammaton
In the Renaissance, Pythagoreanism and the Kabbalah met in a Christian context. Johann Reuchlin (1455–1522) combined Pythagoreanism, Christian theology, and the Kabbalah: in his view, the Kabbalah and Pythagoreanism shared common origins in the Mosaic tradition, and Pythagoras was a Kabbalist. In the treatise De verbo mirifico ("On the Miraculous Word," 1494), Reuchlin compared the tetractys with the Tetragrammaton — the four-letter name of God YHWH.
Agrippa and the Three Books of Occult Philosophy
The systematizer of the numerical tradition was the German humanist, physician, alchemist, and occultist Heinrich Cornelius Agrippa of Nettesheim (1486–1535). His magnum opus — De occulta philosophia ("On the Hidden Philosophy"), written in 1510 and published in 1531–1533; the work consists of three parts — on natural, celestial, and ceremonial magic.
In the Three Books of Occult Philosophy, Agrippa applied arithmancy to the classical Latin alphabet: A = 1 … I = 9, then K = 10 … S = 90, T = 100 and onward by hundreds (the letters U, J, and W were not then considered part of the Latin alphabet; in other editions J = 600 and U = 700 appear).
In the second book, he compiled the Pythagorean and Kabbalistic "scales" of numbers: the "scale of the number ten" (ten names of God, ten sefirot, ten spheres, ten orders of angels), the 32 paths of wisdom, and the 72-letter name of God. By the end of the sixteenth century, purely numerological compendia also appeared: Pietro Bongo's Numerorum mysteria ("Mysteries of Numbers," 1591) — according to English Wikipedia, the most influential numerological treatise in Europe.
Nineteenth–Twentieth Centuries: From Arithmancy to Numerology
The Term "Numerology"
Before the twentieth century, the practice was called arithmancy (the word arithmancy is known in English from the 1570s); the term numerology is not recorded in English earlier than approximately 1907 (Oxford English Dictionary). Both the term and the modern schools are phenomena of the twentieth century.
Cheiro and the "Chaldean" School
The key figure in this process is the Irish astrologer, palmist, and numerologist Cheiro (pseudonym of William John Warner, 1866–1936, also "Count Louis Hamon"; the pseudonym comes from the word cheiromancy, "palmistry"). According to his memoirs, Cheiro learned palmistry, astrology, and "Chaldean numerology" in India from a Chitpavan Brahmin (Konkan valley, Maharashtra) and returned to London after two years; the skeptic James Randi questioned these claims. His main work is Cheiro's Book of Numbers (editions 1930–1932 according to Open Library), in which two schools are named: "Pythagorean and the more ancient, known as Chaldean."
The "Chaldean" school here is a product of reconstruction: Cheiro attributed the alphabet to the "Chaldeans," supposedly passing it on to the Jews; letters receive values 1–8 "by vibration," 9 is absent as sacred, and all two-digit sums are reduced. No direct ancient Chaldean numerological texts have survived — Cheiro himself wrote that the origin of the alphabet "is lost in antiquity."
The historical Chaldeans were Semitic tribes of southern Mesopotamia, and the "Chaldean astrologers" of ancient sources are synonymous with Babylonian priest-astrologers; no direct continuity between Babylonian astrology and Cheiro's table has been attested: a twentieth-century table attributed to an ancient people without reliable sources.
The Formation of the "Pythagorean Method" and English Gematrias
In parallel, the "Pythagorean method" took shape: letters of the Latin alphabet are sequentially assigned values 1–9 (A–I = 1–9, J–R = 1–9, S–Z = 1–8), sums are reduced by adding places to the number 1–9 — mathematically this is equivalent to division by modulo 9; in a number of variants, two-digit 11 and 22 ("dominant," master numbers) are not reduced. This is a simplification of the ancient pythmenes technique, not a direct heritage of the ancient school.
In England, a separate line of letter-number mysticism also developed: an early example is John Skelton's poem The Garland of Laurel (1523), then Willis F. Whitehead's The Mystic Thesaurus (1899) with the "English Cabala" system, and James Lees's English Qaballa (1976).
The Modern Era: New Age and Angel Numbers
In the second half of the twentieth century, numerology became part of New Age culture. The newest layer — "angel numbers": repeating combinations like 111 or 444, to which messages from above are attributed. This genre in its current form was created by Doreen Virtue and Lynnette Brown in 2004 (the book Angel Numbers was published in 2005); by 2023, articles about their meaning were being published en masse by media outlets. After converting to Christianity, Virtue disavowed the concept in an interview with The Cut (October 14, 2024): according to her, it is "garbage," and she "regrets and apologizes" for creating it.
A separate branch is Vedic numerology; in open encyclopedic sources in our fact base, there is insufficient material on it, so the topic requires separate development and is only mentioned here.
Who Invented Numerology
The answer to the question "who invented numerology" cannot be attributed to a single individual: modern numerology was formed from four layers.
Layer | What It Is | When | Where / Who |
|---|---|---|---|
Number symbolism | sacred numbers, isopsephy, gematria | antiquity — Middle Ages | Mesopotamia, school of Pythagoras, Kabbalists |
Term "numerology" | the word numerology | approximately 1907 | English language (OED) |
Modern schools | letter table 1–9, "Chaldean" table, master numbers 11/22 | twentieth century | Cheiro and popular authors |
Angel numbers | meanings of 111, 444 | 2004 | Doreen Virtue and Lynnette Brown |
Four conclusions:
- Number symbolism is ancient. The seven of Mesopotamia, the tetractys and isopsephy of the Pythagoreans, the gematria of the Kabbalists — all this is antiquity and the Middle Ages.
- The term is new. The word "numerology" appears only around 1907; before the twentieth century the practice was called arithmancy.
- Modern systems are twentieth-century reconstructions: the "Pythagorean" table of 1–9 and the "Chaldean" table of Cheiro have no direct ancient original sources, and master numbers 11/22 are not attested among the ancient Pythagoreans.
- Angel numbers are a product of 2004, not a centuries-old tradition.
Therefore, the marketing claim of "numerology that is thousands of years old" is true only for the first layer. Numerology as a practice existing under this name is a phenomenon of the twentieth century.
Scientific Criticism and Status
From a scientific standpoint, numbers have no meaning in themselves and do not affect a person's life. The Skeptic's Dictionary calls numerology superstition and pseudoscience, using numbers to "give the appearance of scientific gloss": the mathematical quality of calculations does not make them scientific.
Direct tests were also conducted: in Great Britain (1993) and in Israel (2012, professional numerologist and 200 participants, experiment repeated twice). Both yielded reproducibly negative results: predictions did not differ from random guessing. In scientific discourse, "numerology" is also used to describe theories inspired by "beautiful coincidences of numbers" rather than observations — for example, Dirac's large numbers hypothesis or Pauli's interest in the number 137.
