Numerology
View on Wikipedia

Numerology (known before the 20th century as arithmancy) is the belief in an occult, divine or mystical relationship between a number and one or more coinciding events. It is also the study of the numerical value, via an alphanumeric system, of the letters in words and names. When numerology is applied to a person's name, it is a form of onomancy. It is often associated with astrology and other divinatory arts.[2]
Number symbolism is an ancient and pervasive aspect of human thought, deeply intertwined with religion, philosophy, mysticism, and mathematics. Different cultures and traditions have assigned specific meanings to numbers, often linking them to divine principles, cosmic forces, or natural patterns.[3]
Etymology
[edit]The term arithmancy is derived from two Greek words – arithmos (meaning number) and manteia (meaning divination). "Αριθμομαντεία" Arithmancy is thus the study of divination through numbers.[4] Although the word "arithmancy" dates back to the 1570s,[5] the word "numerology" was not recorded in English before c. 1907.[6]
History
[edit]The practice of gematria, assigning numerical values to words and names and imputing those values with religious meaning, dates back to antiquity. An Assyrian inscription from the 8th century BC, commissioned by Sargon II declares "the king built the wall of Khorsabad 16,283 cubits long to correspond with the numerical value of his name".[7] Rabbinic literature used gematria to interpret passages in the Hebrew Bible.
The practice of using alphabetic letters to represent numbers developed in the Greek city of Miletus, and is thus known as the Milesian system.[8] Early examples include vase graffiti dating back to the 6th century BCE.[9] Aristotle wrote that the Pythagorean tradition, founded in the 6th century by Pythagoras of Samos, practiced isopsephy,[10] the Greek predecessor of Hebrew gematria. Pythagoras was a contemporary of the philosophers Anaximander, Anaximenes, and the historian Hecataeus, all of whom lived in Miletus, across the sea from Samos.[11] The Milesian system was in common use by the reign of Alexander the Great (336–323 BCE) and was adopted by other cultures during the subsequent Hellenistic period.[8] It was officially adopted in Egypt during the reign of Ptolemy II Philadelphus (284–246 BCE).[8]
By the late 4th century AD, following the Edict of Thessalonica in 380 AD and the subsequent enforcement of Nicene Christianity under Theodosius I, departures from the beliefs of the state church were classified as civil violations within the Roman Empire.[12] Numerology, referred to as isopsephy, remained in use in conservative Greek Orthodox circles, particularly in mystical and theological contexts.[13]
Some alchemical theories were closely related to numerology. For example, Arab alchemist Jabir ibn Hayyan (died c. 806−816) framed his experiments in an elaborate numerology based on the names of substances in the Arabic language.[14]
Numerology is prominent in Sir Thomas Browne's 1658 literary discourse The Garden of Cyrus. Throughout its pages, the author attempts to demonstrate that the number five and the related quincunx pattern can be found throughout the arts, in design, and in nature, particularly botany.[15]
Some approaches to understanding the meanings of the Qur'an (the book of Muslims) include the understanding of numerical meanings, numerical symbols and their combination with purely textual approaches.[16]
Methods
[edit]Alphanumeric systems
[edit]There are various numerology systems which assign numerical value to the letters of an alphabet. Examples include the Abjad numerals in Arabic, Hebrew numerals, Armenian numerals, and Greek numerals. The practice within Jewish tradition of assigning mystical meaning to words based on their numerical values, and on connections between words of equal value, is known as gematria.[17]
The Mandaean number alphasyllabary is also used for numerology (Mandaic: gmaṭ aria). The Book of the Zodiac is an important Mandaean text on numerology.[18]
Pythagorean method
[edit]In the Pythagorean method (which uses a kind of place-value for number-letter attributions, as does the ancient Hebrew and Greek systems), the letters of the modern Latin alphabet are assigned numerical values 1 through 9.[19]
Agrippan method
[edit]
Heinrich Cornelius Agrippa applied the concept of arithmancy to the classical Latin alphabet in the 16th century in Three Books of Occult Philosophy. He mapped the letters as follows (in accordance with the Latin alphabet's place-value at that time):[20]
| 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|
| A | B | C | D | E | F | G | H | I |
| 10 | 20 | 30 | 40 | 50 | 60 | 70 | 80 | 90 |
| K | L | M | N | O | P | Q | R | S |
| 100 | 200 | 300 | 400 | 500 | 600 | 700 | 800 | 900 |
| T | V[a] | X | Y | Z | I[b] | V[c] | HI[d] | HV[e] |
Note that the letters U, J, and W were not commonly considered part of the Latin alphabet at the time.
Angel numbers
[edit]Angel numbers, as defined by Doreen Virtue and Lynnette Brown in 2004, are numbers consisting of repeating digits, such as 111 or 444.[21] As of 2023[update], a number of popular media publications have published articles suggesting that these numbers have numerological significance.[22] Doreen Virtue has since renounced the concept of angel numbers in a 2024 interview with The Cut declaring that, "It’s garbage. I regret it, and I’m sorry that I made them."[23]
English systems
[edit]There are various systems of English Qabalah or numerology.[24] These systems interpret the letters of the Roman script or English alphabet via an assigned set of numerological significances.[25][26] English Qaballa, on the other hand, refers specifically to a Qabalah supported by a system discovered by James Lees in 1976.
The first system of English gematria was used by the poet John Skelton in 1523 in his poem "The Garland of Laurel".[27] The next reference to an English gematria found in the literature was made by Willis F. Whitehead in 1899 in his book The Mystic Thesaurus, in which he describes a system he called "English Cabala".[28]
In 1952, John P. L. Hughes published The Hidden Numerical Significance of the English Language, or, Suggestive Gematria, based on his lecture delivered at Holden Research Circle on July 4, 1952.[29] A system related to the Spiritualist Agasha Temple of Wisdom was described by William Eisen in his two volume The English Cabalah (1980–82).[30][31][32]
William G. Gray proposes another system in his 1984 book Concepts of Qabalah,[33] more recently republished as Qabalistic Concepts.[34] This system includes correspondence attributions of the English letters to the positions on the Tree of Life. Michael Bertiaux described a system called Angelic Gematria in his The Voudon Gnostic Workbook (1989).[35] David Rankine described a system of English gematria[36] using prime numbers which he calls Prime Qabalah in his book Becoming Magick (2004).[37]
In popular culture
[edit]In modern culture, numerology continues to influence personal and public life. For example, Australian MP Sussan Ley credibly altered the spelling of her own name according to numerological advice, believing it would bring excitement to her life, a story widely reported in 2025.[38]
Similarly, celebrities like Gwyneth Paltrow have marked entry into a “9-year” numerological cycle signifying transformation and closure, with symbolic gestures such as posting rain imagery associated with personal renewal.[39]
Related uses
[edit]Scientific theories are sometimes labeled "numerology" if their primary inspiration appears to be a set of patterns rather than scientific observations. This colloquial use of the term is quite common within the scientific community and it is mostly used to dismiss a theory as questionable science.[40]
The best known example of "numerology" in science involves the coincidental resemblance of certain large numbers that intrigued mathematical physicist Paul Dirac, mathematician Hermann Weyl and astronomer Arthur Stanley Eddington.[41] These numerical coincidences refer to such quantities as the ratio of the age of the universe to the atomic unit of time, the number of electrons in the universe, and the difference in strengths between gravity and the electric force for the electron and proton.[42] (See also Fine-tuned universe).
Wolfgang Pauli was also fascinated by the appearance of certain numbers, including 137 (a prime number), in physics.[43]
British mathematician I. J. Good wrote:
There have been a few examples of numerology that have led to theories that transformed society: see the mention of Kirchhoff and Balmer in Good (1962), p. 316 [...] and one can well include Kepler on account of his third law. It would be fair enough to say that numerology was the origin of the theories of electromagnetism, quantum mechanics, gravitation. [...] So I intend no disparagement when I describe a formula as numerological.
When a numerological formula is proposed, then we may ask whether it is correct. [...] I think an appropriate definition of correctness is that the formula has a good explanation, in a Platonic sense, that is, the explanation could be based on a good theory that is not yet known but 'exists' in the universe of possible reasonable ideas.[44]

Numerology
View on GrokipediaEtymology and Terminology
Etymology
The term "numerology" first appeared in English around 1911, denoting the study of the occult meaning of numbers, formed as a hybrid of Latin numerus ("number") and the suffix -logy ("study of").[6] Prior to this, practices involving the mystical significance of numbers were referred to by other terms in English occult literature, with the earliest notable appearance of related concepts in works like William Lilly's 1647 Christian Astrology, which discussed numerical influences without using a unified term. A key historical synonym is "arithmancy," derived from the Greek words arithmos (ἀριθμός, meaning "number") and manteia (μαντεία, meaning "divination"), referring to divination by numbers; the term entered English in the 1570s.[7] In ancient Greek traditions, particularly those influenced by Pythagorean ideas of numerical harmony, the practice was known as isopsephy (ἰσοψηφία), from isos (ἴσος, "equal") and psephos (ψῆφος, "pebble" or "count"), reflecting the use of pebbles for calculation and equating words with matching numerical values.[8] In Hebrew mysticism, the equivalent system is called gematria, a term originating in the 17th century from the Hebrew gimatria (גימטריא), likely borrowed from the Greek geometria (γεωμετρία, "geometry"), where letters of the alphabet are assigned numerical values for interpretive purposes.[9] Similarly, in Arabic and Islamic occult traditions, the abjad system—named as an acronym from the first four letters of the Arabic alphabet (alif, bāʾ, jīm, dāl)—assigns numerical values to letters for mystical calculations, with roots tracing back to ancient Semitic numeral practices.[10] The evolution of this terminology in English occult texts reflects a gradual synthesis of ancient Mediterranean and Semitic influences, with terms like arithmancy appearing in 16th- and 17th-century translations of classical works, while "numerology" emerged in the early 20th century to encompass modern popular interpretations.[7]Core Concepts and Definitions
Numerology posits that numbers possess inherent vibrational qualities or energies that extend beyond their mathematical value, influencing human personality, life events, and overall destiny. This core belief stems from the idea that the universe operates on numerical principles, where each number from 1 to 9—and select compound forms—carries a unique frequency capable of shaping individual experiences and trajectories.[11] A fundamental principle in numerology is the reduction of multi-digit numbers to a single digit between 1 and 9 through iterative addition of their digits, a process known as digit summing or reduction. Exceptions are made for "master numbers" such as 11, 22, and 33, which are not further reduced due to their amplified vibrational potency and are regarded as indicators of heightened spiritual potential or challenges. This reduction method simplifies complex numerical data from birth dates or names into core essences, allowing practitioners to interpret underlying influences without delving into exhaustive calculations.[12] Central to numerological practice is the concept of the numeroscope, which refers to a comprehensive chart or profile derived from an individual's birth date and full name, mapping out personal vibrations and destiny pathways. Key components include the destiny number (also called the expression number), calculated from the full birth name to reveal innate talents, potential challenges, and life's overarching purpose; the soul urge number (or heart's desire number), derived from the vowels in the name to uncover inner motivations and deepest aspirations; and the personality number, based on the consonants in the name, which indicates the outward persona and how one is perceived by others. These elements collectively form a symbolic framework for self-understanding.[13][11] While numerology functions as a form of divination by using these numerical symbols to predict or interpret life patterns, it fundamentally relies on mathematical symbolism rather than empirical prediction, distinguishing it from purely probabilistic or scientific analyses. The term "vibration," rooted in occult traditions, underscores this symbolic approach, evoking energetic resonances rather than literal physical oscillations.Historical Development
Ancient Origins
Early practices resembling numerology, involving the mystical or divinatory use of numbers, are attested in ancient Mesopotamia from the third millennium BCE, with systematic numerical calculations in omen interpretations documented by the Neo-Assyrian period in the 8th century BCE, where Assyrian and Babylonian scholars employed numerical patterns from planetary observations and ritual texts to forecast events, marking a systematic integration of arithmetic with prophetic inquiry.[14] These methods, predating formalized gematria, relied on base-60 mathematics to assign significance to quantities in omens, such as lunar phases or star positions, reflecting a belief in numbers as mediators between the divine and human realms.[15] Parallel developments appear in ancient Mesoamerica, where numerical cycles in the Mayan Long Count calendar (ca. 2000 BCE onward) were used for divinatory and cosmological purposes.[16] In ancient Egypt and Mesopotamia, numbers also permeated calendars and monumental architecture, embodying cosmic order and harmony. The Egyptian civil calendar, established by around 3000 BCE, structured time into 365 days across 12 months of 30 days plus five epagomenal days, symbolizing the annual Nile flood and solar cycle to ensure agricultural and ritual alignment.[17] Architecturally, the pyramids of Giza, constructed circa 2580–2560 BCE, incorporated precise numerical ratios—such as the seked slope of 5.5 palms per cubit—and cardinal alignments to the north pole star, integrating sacred geometry to connect earthly structures with eternal celestial patterns.[18] Mesopotamian counterparts, like the ziggurats of the 3rd millennium BCE, scaled dimensions using sexagesimal units derived from astronomical observations, embedding numerical symbolism in temple designs to represent the layered cosmos.[19] Pre-Pythagorean Greek influences on numerical mysticism arose in Ionian philosophy during the 6th century BCE, where early thinkers shifted from mythological to rational explanations of the universe, incorporating quantitative elements in cosmological models. Figures like Thales of Miletus (c. 624–546 BCE) and Anaximander (c. 610–546 BCE) proposed arche (originating principles) involving measurable phenomena, such as water or the indefinite, which implicitly relied on numerical harmony to describe natural processes and foreshadowed the tetraktys as a symbol of cosmic structure.[20] This Ionian emphasis on observation and proportion provided precursors to Pythagoras' later doctrines, bridging empirical measurement with emerging ideas of numbers as fundamental essences. Ancient Chinese and Indian systems further illustrate early numerological frameworks through divination and astrology. The I Ching, originating in the Western Zhou dynasty (c. 1046–771 BCE), features 64 hexagrams composed of six yin-yang lines, representing binary numerical progressions (2^6=64) that correlate with natural changes, seasonal cycles, and human affairs for oracular guidance.[21] In Vedic India, from the late Vedic period (c. 1100–500 BCE), Jyotisha texts like the Vedanga Jyotisha integrated numerical correspondences—such as 27 nakshatras (lunar mansions), 12 rashis (zodiac signs), and planetary cycles—into horoscopic calculations to divine auspicious timings and personal fates, viewing numbers as vibrations of divine order.[22]Classical and Medieval Periods
In the classical period, numerology found its most influential philosophical foundation in the teachings of Pythagoras and his followers in ancient Greece. Pythagoras (c. 570–495 BCE) established a school that viewed numbers not merely as quantitative tools but as the essential principles underlying the cosmos, governing harmony, music, and the structure of reality itself. This doctrine emphasized that all things are composed of numbers, with even and odd representing fundamental opposites that underpin the universe's order. Central to Pythagorean symbolism was the tetractys, a sacred figure consisting of ten dots arranged in four rows (1+2+3+4=10), symbolizing the decad as the source of all harmony and the blueprint of creation, often invoked in oaths and rituals by the school.[23][24] During the Hellenistic era, numerological practices evolved through isopsephy, the Greek equivalent of gematria, where letters of the alphabet were assigned numerical values to decode mystical significances in names, words, and texts. This method, rooted in earlier Pythagorean ideas, became widespread in philosophical, oracular, and literary contexts, allowing interpreters to equate words with equal numerical sums to reveal divine or prophetic insights. Isopsephy's dissemination was advanced by Neoplatonism, a third-century CE philosophical movement led by figures like Plotinus and Iamblichus, who incorporated numerical symbolism into their hierarchical metaphysics, portraying numbers as intermediaries between the transcendent One and the material world, thus bridging esoteric traditions across the Greco-Roman world.[25][26][27] In the medieval Islamic world, numerology integrated Greek legacies with Arabic innovations, particularly through letter-number correspondences in the abjad system, where each letter of the Arabic alphabet held a fixed numerical value for use in science, astrology, and mysticism. Al-Kindi (c. 801–873 CE), often called the "Philosopher of the Arabs," contributed significantly in the 9th century by exploring these correspondences in his treatises on harmonics, astrology, and cryptology, where he analyzed letter frequencies and numerical patterns to link linguistic elements with cosmic and musical proportions, laying groundwork for later occult applications. His works, such as those on the mathematical foundations of music and stellar influences, demonstrated how numerical values of letters could reveal hidden harmonies in nature and the heavens.[28] The medieval period also witnessed the rise of Jewish Kabbalah in 12th- and 13th-century Provence, where gematria emerged as a core mystical technique for interpreting sacred texts. Emerging among scholars in southern France, such as Isaac the Blind (c. 1160–1235 CE), Kabbalah synthesized earlier Jewish esoteric traditions with theosophical speculation, using gematria to compute the numerical equivalents of Hebrew words and phrases, thereby uncovering interconnections between divine names, biblical verses, and metaphysical realities. This practice, which equated words of equal value to signify conceptual unity, facilitated profound explorations of God's sefirot (emanations) and the Torah's hidden layers, marking a pivotal fusion of numerology with Jewish mysticism that influenced subsequent European esoteric thought.[29][30]Renaissance to Modern Era
During the Renaissance, Heinrich Cornelius Agrippa's Three Books of Occult Philosophy (1533) marked a pivotal systematization of numerical correspondences in Western esotericism, linking numbers to elements, planets, and spiritual forces through the doctrine of signatures and Kabbalistic influences.[31] This work compiled and expanded upon ancient and medieval traditions, assigning mystical significances to numbers such as 1 for unity and 7 for perfection, thereby laying foundational frameworks for later numerological practices.[32] In the 19th century, the Theosophical Society, co-founded by Helena Blavatsky in 1875, revived interest in numerology by integrating it with Eastern mysticism, particularly through symbolic interpretations of numbers like the tetractys (a Pythagorean figure representing cosmic harmony) and the hebdomad (seven as a sacred cycle).[33] Blavatsky's writings, such as The Secret Doctrine (1888), emphasized numerological patterns in cosmic evolution, blending Hindu, Buddhist, and Western occult elements to portray numbers as keys to universal laws. This synthesis influenced subsequent esoteric movements by framing numerology as a bridge between science, religion, and hidden wisdom. The early 20th century saw numerology's popularization in America through L. Dow Balliett's The Philosophy of Numbers: Their Tone and Colors (1908), which introduced vibrational interpretations of numbers derived from names and birthdates, adapting Pythagorean principles for personal guidance.[34] Balliett's approach emphasized numbers' harmonic qualities, associating them with colors and sounds to reveal individual destinies. Around the same period, Dr. Julia Seton, a student of Balliett, coined the term "numerology" in her teachings and writings, formalizing it as a modern science of numbers for self-improvement and prophecy.[35] Following World War II, numerology experienced a surge within the New Age movement, which emerged in the 1950s and peaked in the 1970s–1980s as part of broader countercultural explorations of spirituality and self-help. This era popularized numerology through books, workshops, and media, often linking it to astrology and holistic healing for personal transformation. By the early 21st century, high-profile endorsements sustained its visibility; for instance, in 2025, Australian politician Sussan Ley, newly elected as Liberal Party leader, reflected on her youthful name change from Susan to Sussan, inspired by numerology's promise of an "incredibly exciting" life through numerical vibrations.[36] Similarly, actress Gwyneth Paltrow publicly embraced the 9-year numerological cycle in 2024, describing it as a phase of completions and letting go, which she used to process personal transitions like family changes.[37]Core Methods and Calculations
Examples of numerological theories include Pythagorean numerology, which derives insights from names and dates through letter-to-number assignments and reductions; Kabbalistic numerology, employing gematria to equate words with numerical values for hidden meanings; date reduction, summing the digits of birth dates to a single digit or master number to determine vibrational life paths; and number vibrations, assigning inherent energies to numbers, such as 3 for creativity and 7 for mysticism.Alphanumeric Systems
Alphanumeric systems form a foundational aspect of numerology, enabling the conversion of written names into numerical equivalents to reveal vibrational patterns believed to influence personal traits and life paths. These systems typically assign sequential values to letters of an alphabet, such as A=1 through Z=26 in modern Latin-based approaches, allowing practitioners to sum the values of a name's letters for interpretive analysis. Historically, such alphanumeric practices trace back to ancient traditions where letters inherently carried numerical significance. In Hebrew gematria, dating to at least the Second Temple period, each letter of the 22-letter alphabet is assigned a value starting with Aleph=1, Beth=2, and extending to Tav=400, used to uncover hidden meanings in sacred texts through equivalences of words with equal sums. The Greek counterpart, isopsephy, emerged around the 4th century BCE and similarly equates letters to numbers—alpha=1, beta=2, up to omega=800—facilitating mystical interpretations in philosophical and oracular contexts.[38] In the Arabic abjad system, developed by the 8th century CE, the 28 letters receive values from alif=1 to ghayn=1000, often applied in poetry, chronology, and esoteric calculations across Islamic scholarship.[39] A key principle in many alphanumeric systems distinguishes between vowels and consonants to differentiate aspects of the self. Vowels (A, E, I, O, U, and sometimes Y) are summed separately to represent the "inner self" or soul urges—reflecting motivations and desires—while consonants capture the "outer self" or personality traits visible to others, a distinction rooted in early 20th-century numerological texts that emphasized vibrational differences. This separation allows for layered interpretations, such as comparing inner and outer numbers to assess harmony or conflict in an individual's expression. To derive core numbers, alphanumeric systems commonly employ reduction techniques, where the total sum of letter values is repeatedly added until a single digit (1 through 9) is obtained, symbolizing a fundamental essence; master numbers like 11 or 22 may be retained in some variants before final reduction. The Pythagorean system, influential in Western numerology, adapts this framework with a modular 1-9 assignment to letters.Pythagorean System
The Pythagorean system of numerology, one of the most prevalent methods in Western numerology, attributes numerical values to letters of the alphabet and derives personal insights from birth dates and names by reducing sums to single digits or master numbers.[40] This approach traces its conceptual roots to the philosophical teachings of Pythagoras, emphasizing the vibrational essence of numbers in shaping human experience.[41] The core of the system is the Pythagorean chart, which maps the 26 letters of the English alphabet to numbers 1 through 9 in a repeating sequence. Specifically, A, J, and S correspond to 1; B, K, and T to 2; C, L, and U to 3; D, M, and V to 4; E, N, and W to 5; F, O, and X to 6; G, P, and Y to 7; H, Q, and Z to 8; and I and R to 9.[40] This chart forms the basis for converting names into numerical equivalents, allowing practitioners to analyze traits and potentials. A key calculation in the Pythagorean system is the life path number, derived from an individual's birth date by summing all digits and reducing the total to a single digit, unless it results in a master number like 11, which is retained for its intensified significance. For example, for a birth date of December 25, 1990, the digits are added as 1 + 2 + 2 + 5 + 1 + 9 + 9 + 0 = 29, then further reduced to 2 + 9 = 11, indicating a master number associated with heightened intuition.[41] This number is interpreted as outlining the primary lessons and direction of one's life journey. In addition, the system uses similar digit reduction techniques to calculate temporal personal cycles for insights into periodic energies. The personal year number is calculated by adding the birth month and birth day to the current year, then reducing to a single digit or master number (11, 22, or 33). The personal month number is obtained by adding the personal year number to the current month number and reducing. The personal day number is derived by adding the personal month number to the current day of the month and reducing similarly. These numbers are interpreted as reflecting the vibrational energy or influence of the respective time period. Some sources compute the personal day number directly by summing the birth month, birth day, current month, current day, and current year before reduction, which yields the same result mathematically.[42] Name-based numbers provide additional layers of insight, with the destiny number calculated from the full birth name by assigning chart values to each letter, summing them, and reducing as above to reveal overall life purpose and opportunities. The personality number, in contrast, focuses on the first name, similarly summed to highlight outward traits and how one is perceived by others.[43] Each number from 1 to 9 carries distinct symbolic meanings in the Pythagorean system, while master numbers amplify these qualities. Number 1 signifies leadership, independence, and originality; 2 represents cooperation, diplomacy, and sensitivity; 3 embodies creativity, expression, and sociability; 4 denotes stability, discipline, and practicality; 5 indicates freedom, adaptability, and adventure; 6 symbolizes responsibility, harmony, and nurturing; 7 reflects introspection, spirituality, and analysis; 8 conveys ambition, authority, and material success; and 9 suggests compassion, idealism, and universal love. Master numbers, such as 11 (intensified 2, a gateway of spiritual intuition, illumination, and heightened sensitivity that connects the individual to higher realms and collective consciousness) and 22 (intensified 4, denoting masterful building and practical achievement), are not reduced and denote elevated potential with corresponding challenges.[40][41][44]| Letter | Number | Letter | Number | Letter | Number |
