Arcana is a Latin term meaning 'secrets' or 'mysteries,' used to refer to tarot cards. A standard deck comprises 22 Major Arcana and 56 Minor Arcana, totaling 78 cards.
Arcana is the plural form of the Latin word "arcanum," meaning "secret" or "mystery." In tarot, it refers to the two main divisions of a 78-card deck: the Major Arcana (22 cards representing life's great mysteries) and the Minor Arcana (56 cards representing everyday experiences). The concept of arcana provides the foundational framework through which tarot practitioners understand and organize the rich symbolic language of the cards.
The word "arcana" carries a weight of meaning that goes far beyond a simple label. It implies that the tarot contains layers of hidden knowledge—truths that are not immediately apparent to the casual observer but reveal themselves progressively to those who study the cards with dedication and an open mind. This notion of concealed wisdom is what distinguishes tarot from ordinary playing cards and elevates it into the realm of divination, meditation, and psychological exploration.
Understanding the concept of arcana is essential for anyone beginning their tarot journey, as it shapes how readings are interpreted and how the relationship between the Major and Minor divisions creates a complete picture of human experience. Whether you approach tarot as a spiritual practice, a psychological tool, or a framework for self-reflection, the idea of arcana—hidden truths waiting to be uncovered—remains at the heart of the practice.
The word "arcanum" has deep roots in Western intellectual history. It derives from the Latin "arca," meaning "chest" or "box"—a container for things kept hidden. In medieval and Renaissance alchemy, "arcana" referred to the secret processes by which base metals could supposedly be transformed into gold. The alchemists guarded their arcana jealously, encoding their knowledge in symbolic language that only fellow initiates could decipher.
The application of the term to tarot cards emerged during the 18th century, when French occultists began reinterpreting the tarot as a repository of ancient wisdom rather than merely a card game. Antoine Court de Gébelin, in his 1781 work "Le Monde primitif," proposed that tarot cards encoded the secret teachings of ancient Egypt. Although this theory has been thoroughly debunked by modern historians, it established the framework within which tarot cards came to be seen as "arcana"—vessels of hidden knowledge.
The formalization of the Major and Minor Arcana as distinct categories occurred primarily through the work of 19th-century occultists. Éliphas Lévi, in his influential "Dogme et Rituel de la Haute Magie" (1856), drew extensive correspondences between the 22 Major Arcana cards and the 22 letters of the Hebrew alphabet, linking tarot to the Kabbalistic tradition. The Order of the Golden Dawn further systematized these correspondences, assigning astrological, elemental, and Kabbalistic attributions to every card in the deck.
The Rider-Waite deck, published in 1909, brought the concept of arcana to a wider audience by providing fully illustrated scenes for every card, including the pip cards of the Minor Arcana. This made the "secrets" encoded in each card more visually accessible, democratizing knowledge that had previously been restricted to esoteric circles.
At its most fundamental level, the concept of arcana in tarot refers to the idea that each card contains symbolic knowledge that can be "unlocked" through study, intuition, and practice. The 78 cards of a standard tarot deck are divided into two categories:
| Division | Cards | Focus | Symbolic Level |
|---|---|---|---|
| Major Arcana | 22 (0-21) | Universal archetypes, spiritual lessons, major life events | The "greater mysteries" — transformative, karmic forces |
| Minor Arcana | 56 (4 suits × 14) | Daily life, practical matters, emotions, thoughts | The "lesser mysteries" — everyday experiences and choices |
The distinction between "greater" and "lesser" mysteries does not imply that one is more important than the other. Rather, it reflects two complementary levels of experience. The Major Arcana speaks to the soul-level journey—the deep patterns and transformations that define a life. The Minor Arcana speaks to the day-to-day reality—the specific situations, feelings, and decisions through which those larger patterns manifest.
The term "lesser mysteries" for the Minor Arcana is borrowed from the ancient Greek mystery schools, particularly the Eleusinian Mysteries, which had two stages of initiation. The lesser mysteries prepared the initiate for the greater revelations to come. Similarly, understanding the Minor Arcana's practical wisdom prepares the tarot student for the deeper archetypal truths of the Major Arcana.
The organizational structure of the arcana reflects a sophisticated symbolic system:
Major Arcana Structure:
Minor Arcana Structure:
Each suit contains numbered cards (Ace through 10) and four court cards (Page, Knight, Queen, King), creating a progression from inception to mastery within each elemental domain.
| Tradition | Major Arcana | Minor Arcana | Key Difference |
|---|---|---|---|
| Marseille | Named trumps | Unillustrated pips | Pip cards show only suit symbols |
| Rider-Waite | Fully illustrated | Fully illustrated | Scenic pips with narrative imagery |
| Thoth | Renamed some cards | Renamed court cards | Incorporates dense esoteric symbolism |
| Modern/Indie | Varies widely | Varies widely | Creative reinterpretations of traditional arcana |
Carl Jung's concept of archetypes provides a powerful lens for understanding the arcana. Jung proposed that the human psyche contains universal patterns—archetypes—that manifest across cultures and throughout history. The Major Arcana cards map remarkably well onto these archetypes: The Fool as the eternal child, The Empress as the Great Mother, The Hermit as the Wise Old Man, and so forth.
From this perspective, the "secrets" of the arcana are not external mysteries but internal ones—aspects of the psyche that remain hidden until brought to conscious awareness through reflection and self-examination. A tarot reading becomes a dialogue with the unconscious, using the arcana as a symbolic vocabulary for articulating what the conscious mind has not yet grasped.
Understanding the distinction between Major and Minor Arcana is crucial for interpreting readings effectively:
Assess the ratio: Count how many Major vs. Minor Arcana cards appear in a spread. A reading dominated by Major Arcana cards suggests powerful, often unavoidable forces at work. A predominantly Minor Arcana reading indicates that the situation is more within the querent's immediate control.
Identify the narrative level: Major Arcana cards tell the "big story"—the karmic or spiritual dimension of a situation. Minor Arcana cards fill in the practical details—what actions to take, what emotions to expect, what challenges to prepare for.
Note suit distribution: If most Minor Arcana cards belong to one suit, that element's domain (emotions, intellect, material concerns, or creative energy) is the primary area of focus.
Watch for Major Arcana in key positions: When a Major Arcana card appears in a pivotal position within a spread (such as the outcome or crossing card), it amplifies the significance of that position.
Many practitioners use the arcana as meditation focal points. The Major Arcana cards, with their rich archetypal imagery, are particularly well-suited for this practice. Meditating on a single card—studying its symbols, colors, and figures—can unlock personal insights that go beyond intellectual understanding.
Keeping a tarot journal organized by arcana helps track patterns in readings over time. Note which Major Arcana cards appear repeatedly in your readings—these may indicate ongoing life themes or lessons. Similarly, tracking which Minor Arcana suits dominate your readings reveals which areas of life are demanding the most attention.
| Concept | Definition | Relationship to Arcana |
|---|---|---|
| Tarot | The complete 78-card divination system | Arcana is the organizational principle that structures the tarot deck |
| Major Arcana | The 22 trump cards (0-21) | The "greater mysteries" division of the arcana |
| Minor Arcana | The 56 suited cards | The "lesser mysteries" division of the arcana |
| Suit | One of four elemental groupings | The organizational principle within the Minor Arcana |
| Pip Cards | Numbered cards (Ace-10) | The numbered portion of each Minor Arcana suit |
| Court Cards | Face cards (Page-King) | The personality/rank portion of each Minor Arcana suit |
| The Fool's Journey | Narrative arc of the Major Arcana | A storytelling framework that connects the 22 greater arcana |
| Kabbalah | Jewish mystical tradition | Provides correspondences for both Major and Minor Arcana |
The division reflects two levels of human experience, mirroring the structure of ancient mystery schools that distinguished between "greater" and "lesser" mysteries. The Major Arcana addresses universal, archetypal themes—love, death, transformation, spiritual awakening—that operate on a soul level. The Minor Arcana addresses practical, everyday matters—work challenges, emotional dynamics, intellectual decisions, financial concerns—that shape our daily lives. Together, they provide a complete symbolic map of human experience, from the most mundane to the most transcendent.
Yes, Major Arcana-only readings are a valid and powerful approach, particularly for questions about spiritual growth, major life decisions, or karmic patterns. Many tarot practitioners use 22-card Major Arcana readings when the querent seeks guidance on deep, transformative issues. However, without the Minor Arcana, you lose the practical detail and everyday context that helps translate big themes into actionable guidance. For comprehensive readings that address both the "why" and the "how," the full 78-card deck is recommended.
Outside of tarot, "arcanum" (singular of "arcana") means a deep secret or mystery. It appears in academic and literary contexts to describe knowledge that is hidden, restricted, or accessible only to specialists. In pharmaceutical history, "arcana" referred to secret remedies. In political discourse, "arcana imperii" meant the hidden mechanisms of state power. In tarot specifically, it refers to the hidden wisdom encoded in the cards' symbolism—secrets that reveal themselves through study, intuition, and practice.
While all standard tarot traditions maintain the 22/56 division between Major and Minor Arcana, the depth of esoteric meaning assigned to each card varies significantly. The Marseille tradition treats the arcana primarily through numerological and suit-based interpretation. The Rider-Waite tradition emphasizes visual storytelling and intuitive reading. The Thoth tradition layers dense astrological, Kabbalistic, and alchemical correspondences onto each card. Modern and indie decks may reimagine the arcana through diverse cultural lenses while preserving the fundamental two-tier structure.
Absolutely. The word appears in numerous contexts: in alchemy (referring to secret processes), in political theory ("arcana imperii" — the secrets of governance), in pharmacology (secret remedies), and in general literary usage as a synonym for mysteries or secrets. Its adoption into tarot terminology reflects the historical moment when occultists reframed card reading as an esoteric practice connected to ancient hidden wisdom traditions.
The Major Arcana consists of 22 key cards in a tarot deck, numbered from The Fool (0) to The World (21), representing life's significant themes and spiritual growth.
