Featured Academic Resource: The Great Irish Famine
Ancient symbols have been used to express ideas about life, belief, identity, power, protection, ritual and the world around us. But their meanings are not always simple or universal. A symbol may have different meanings in different cultures and periods, and what seems obvious today may not be what people understood in the past. This collection explores 15 ancient symbols and symbolic traditions, looking at their historical contexts, uses and surviving evidence — and asking what we can reasonably know about what they meant.
Symbols have helped people communicate ideas that are difficult to express through words alone. Across different cultures and periods, visual forms have been used to express belief, identity, authority, protection, ritual and ideas about the natural world. They have also appeared in writing, on objects, in buildings, in manuscripts and in works of art.
But a symbol does not have one universal meaning simply because its shape is recognisable. The people who used it, the time and place in which it appeared, and the purpose for which it was made all matter. The same visual form can carry different meanings in different historical settings, while a meaning that seems obvious today may have developed much later.
A symbol's meaning cannot always be understood from its appearance alone. Historians look at the evidence surrounding it: where it was found, when it was made, who used it, what it was used for, and what other objects, images, inscriptions or texts appear with it.
Archaeological remains, inscriptions, manuscripts, artworks and written sources can all provide clues. Sometimes these sources give us strong evidence for how a symbol was used. In other cases, the evidence is incomplete, or different interpretations remain possible.
This is why historians distinguish between what the evidence shows, what scholars interpret, and what remains uncertain. A familiar symbol may have acquired a later meaning, while a symbol that looks similar to another may have developed independently. Understanding the difference requires attention to context, time and evidence.
The word “ancient” can make very different symbols and traditions appear to belong to the same historical world. They do not. The symbols in this collection come from different cultures, regions and periods, and some continued to develop long after their earliest known use.
Throughout this page, “ancient” is therefore used as a broad starting point rather than a precise historical category. Some examples have very early origins; others belong to later historical traditions or have meanings that changed over time. Where chronology matters, we distinguish between an early form, a later tradition and a modern interpretation.
This matters because a symbol that looks familiar today may not have meant the same thing in an earlier period — and two similar-looking symbols are not necessarily historically connected.
The 15 examples below come from different cultures, regions and historical periods. Some are associated with ancient civilizations, while others developed in later traditions or changed significantly over time. Together, they show why understanding an ancient symbol is rarely as simple as looking at its shape and assigning a meaning.
For each symbol, we look at its historical setting, how it was used, what surviving evidence can tell us, and where interpretation or uncertainty begins.
Ancient Egyptian hieroglyph associated with life, found in religious, royal and funerary imagery.
Complementary concepts in Chinese thought, represented by the familiar yin-yang visual form.
Intricate interwoven designs prominent in Insular and early medieval manuscripts, metalwork and stonework.
Sacred syllable and visual form with a central place in Hindu religious and philosophical traditions.
Ancient Egyptian wedjat associated with Horus and used in protective and healing contexts.
Three-part spiral motifs found in different historical settings, raising questions about continuity and interpretation.
An ancient geometric form used across several cultures, with meanings that changed profoundly over time.
Akan visual symbols used to communicate ideas, values and proverbs through material and cultural traditions.
A hand-shaped protective motif whose meanings vary across Jewish, Islamic and other cultural traditions.
Sacred geometric diagram associated with Hindu ritual, meditation and philosophical traditions.
Fish symbol associated with early Christianity and linked to the Greek word for fish.
Buddhist wheel symbol associated with the Buddha's teachings and the path of practice.
A five-pointed form used in different historical traditions, acquiring new meanings across time.
Visual signs used within Maya writing and calendrical systems, rather than simply as abstract symbols.
A recurring visual motif whose similarity across cultures does not by itself prove a shared origin.
The strongest evidence for the meaning of the ankh comes from ancient Egyptian writing itself. The sign was used for ideas connected with life, being alive and living, and it also became a wider visual expression of life.
The ankh appears repeatedly in Egyptian religious and royal imagery. Gods are often shown holding or presenting the sign, while rulers may be shown receiving or carrying it. It appears in inscriptions, monumental art and objects associated with religious and funerary settings, showing that its use extended beyond written language.
The evidence also suggests that the ankh could function as a protective or meaningful object in its own right. It appears on amulets and other objects, sometimes alongside other Egyptian signs. This shows how symbols could work together to express related ideas rather than having a single isolated function.
What we should be careful about is explaining the ankh's shape. Modern interpretations sometimes assign a separate meaning to the loop, crossbar and vertical stem, but the surviving evidence does not allow us to treat these geometric explanations as established ancient Egyptian beliefs.
Why the Ankh matters: the ankh shows the difference between a meaning that is strongly supported by historical evidence and an interpretation that goes beyond what the evidence can prove. Its association with life is well supported. The deeper question of why the sign took this particular form remains much less certain.
The familiar black-and-white yin-yang symbol is closely associated today with ideas of balance, but the historical story is more complex. Yin and yang are complementary concepts in Chinese thought, used to describe contrasting yet interconnected aspects of the natural and social world.
The concepts developed within early Chinese philosophical traditions and were used to explain patterns such as dark and light, receptive and active, and other contrasting forces. Importantly, yin and yang were not simply understood as “good” and “bad.” Their relationship was one of interaction, change and dependence.
The familiar circular taijitu form should not be treated as though it were the original ancient representation of these ideas. The concepts of yin and yang have a much longer history than the particular visual form that became familiar later. This distinction matters because a modern or later symbol can easily be projected backwards onto earlier traditions.
The yin-yang tradition also reminds us that symbols can represent relationships rather than individual things. Its significance lies not simply in two contrasting shapes, but in the idea that opposing qualities can exist together, influence one another and change over time.
Why Yin-Yang matters: it shows why historians need to distinguish between an ancient idea and the visual form through which that idea is represented. The concepts have a long history, but the familiar symbol cannot automatically be assumed to have carried exactly the same form or meaning in every period.
Interlaced patterns are among the most distinctive features of Insular and early medieval art, appearing in manuscripts, stonework, metalwork and other objects across Britain and Ireland. The designs are made from bands or strands that weave over and under one another, creating complex patterns that can be difficult to follow visually.
The term “Celtic interlace” can be useful as a modern description, but it can also be misleading. The surviving examples come from different communities and historical settings, including Anglo-Saxon as well as Irish and other Insular traditions. The Creeton fragments, for example, show interlace in an Anglo-Saxon context. This makes it difficult to treat interlace as the unique symbol of a single “Celtic” culture.
Interlace also illustrates the limits of assigning symbolic meanings to visual patterns. Modern explanations sometimes suggest that the continuous or apparently endless designs represented eternity, interconnectedness or spiritual ideas. Some such interpretations may be possible in particular contexts, but the visual pattern alone does not prove them.
Why Celtic Interlace matters: it shows how a familiar modern label can hide a more complicated historical picture. Similar artistic techniques can appear across different communities, and understanding them requires attention to time, place, material and context rather than assuming that a recognisable pattern had one universal meaning.
Om is a sacred syllable and visual form with a central place in Hindu religious and philosophical traditions. It appears in religious texts, prayers, meditation and ritual practice, where it is treated not simply as a written symbol but as a sound with spiritual significance.
The historical evidence shows that Om has both a linguistic and a visual history. Its importance is rooted in the spoken sacred syllable and its use in religious practice, while the familiar written form developed through scripts used to represent that sound. The sound, the written sign and the philosophical ideas associated with it should therefore not be treated as exactly the same thing.
Different Hindu traditions have interpreted Om within broader ideas about sacred sound, consciousness and ultimate reality. These interpretations are part of living religious traditions and have developed over long periods, rather than representing one fixed meaning shared across all periods and communities.
Why Om matters: Om shows that a symbol can represent more than an image. Its historical significance comes from the relationship between sound, language, writing and religious practice. Understanding it therefore requires looking beyond the shape of the symbol itself.
The Eye of Horus, also known as the wedjat, was an important symbol in ancient Egyptian religious culture. Its association is connected with the god Horus and with the story of the injured and restored eye, which helped establish its relationship with ideas of protection, restoration and well-being.
The symbol appears in many forms of Egyptian material culture, including amulets, jewellery, inscriptions and painted decoration. Its presence on objects intended to protect the wearer shows that the Eye of Horus was not simply an image representing a mythological story; it could also function as a protective object in everyday and funerary contexts.
The story of Horus's injured eye is particularly important because it helps explain why the symbol became associated with restoration and protection. But the meaning of the wedjat should not be reduced to a single modern formula. Its significance depended on the religious and material context in which it appeared.
The familiar modern interpretation can also encourage us to see the symbol as a simple emblem with one fixed meaning. Ancient Egyptian evidence suggests something more complex: symbols could participate in ritual, religious belief and practical protection at the same time.
Why the Eye of Horus matters: it demonstrates how mythology, religious practice and physical objects can reinforce one another. To understand the symbol, we need to consider not only what it looks like, but where it was used, what object it appeared on and what role that object played.
Three-part spiral designs appear in several different historical and cultural settings. The best-known ancient example is the triple spiral carved at Newgrange in Ireland, created during the Neolithic period, thousands of years before the societies later described as Celtic existed.
The Newgrange motif is therefore important precisely because its original meaning is not securely known. Archaeologists can identify where it appears, how it was carved and the broader ritual context of the monument, but there is no surviving written explanation telling us what the people who created it intended it to represent.
Later three-part motifs, including those associated with Celtic and other European traditions, belong to different historical contexts. Their resemblance to the Newgrange spirals does not by itself demonstrate that they share a common origin or meaning.
This is also why the terms triskelion and triple spiral should be used carefully. Similar three-part designs can be grouped visually, but a visual category is not necessarily a historical tradition.
Why Triskelion & Triple Spiral matters: this example reminds us that similar appearance is not enough to establish historical continuity. Before connecting two symbols across time, we need evidence showing that the connection actually existed.
The swastika is an ancient geometric form that appears in the material and visual traditions of different cultures across Asia, Europe and elsewhere. Its long history is important because the same basic shape has been used in very different historical settings and with very different meanings.
In South Asian religious traditions, the swastika has been associated with ideas such as auspiciousness, prosperity and well-being, and it remains part of living religious and cultural practice. Related forms have also appeared in other historical societies, including ancient Europe, where their significance depended on the particular culture and context.
There is therefore no single meaning that can be applied to every historical swastika. A shape found on an ancient object should be interpreted through its date, location, material, surrounding imagery and cultural setting rather than through a modern definition.
The symbol's history was profoundly altered in the twentieth century when the Nazi movement adopted a particular rotated form as its emblem. That political appropriation gave the swastika a very different and deeply disturbing meaning in much of the modern Western world. It should not, however, be projected backwards onto every earlier occurrence of the form.
Why the Swastika matters: it demonstrates perhaps more clearly than any other example that a symbol's meaning depends on historical context. The same visual form can carry entirely different meanings across cultures and periods, and later associations do not erase its much longer history.
Adinkra symbols belong to the Akan visual traditions of West Africa, particularly those associated with Asante culture. They are used to communicate ideas, values, proverbs and aspects of social life through repeated visual forms.
Adinkra is not simply a collection of abstract signs with fixed meanings. Individual symbols are connected to particular concepts, sayings or cultural ideas, and their meaning is shaped by the context in which they are used. They have appeared on cloth and other forms of material culture, with their use extending beyond decoration.
The history of Adinkra also challenges the habit of placing every well-known symbol into a vaguely defined “ancient” past. Adinkra is part of a living cultural tradition whose meanings and uses have continued to develop. Treating it as a static set of ancient symbols removes much of the cultural context that gives the system its significance.
Why Adinkra matters: it shows that symbols can form part of a living system of visual communication. To understand them, we need to consider the community that created and used them, the ideas they express, and the context in which they appear.
The Hamsa is a hand-shaped protective motif found across several cultural and religious traditions, particularly in Jewish and Islamic contexts. Its widespread use can make it tempting to treat the Hamsa as a single ancient symbol with one continuous meaning, but its history is more varied.
The hand is commonly associated with protection, blessing and good fortune, but the significance of the motif depends on the tradition and context in which it appears. It has been used in jewellery, household objects, amulets and decorative art, sometimes alongside religious words, inscriptions or other symbols.
The Hamsa also demonstrates how similar protective imagery can exist across neighbouring cultures without necessarily having one clearly identifiable point of origin. Connections between traditions are possible and, in some cases, historically documented, but similarity of form alone is not enough to establish a shared origin.
Its meaning has also changed and developed over time. Modern representations may combine historical, religious and cultural associations in ways that were not necessarily present in earlier periods.
Why the Hamsa matters: it shows how a symbol can cross cultural and religious boundaries while acquiring different meanings in different settings. Understanding it requires looking at who used it, when and where it appeared, and what other evidence surrounds it.
The Sri Yantra is a sacred geometric diagram associated with Hindu religious and philosophical traditions, particularly forms of Shakta practice. It consists of interlocking triangles arranged around a central point, or bindu, creating a highly structured visual composition.
The diagram is used in ritual, meditation and religious practice, where its geometric arrangement carries significance within particular traditions. Its meaning therefore comes not simply from the shapes themselves, but from the ideas, practices and interpretations connected with the diagram.
The Sri Yantra is sometimes presented as though every triangle, layer and geometric feature has one universally accepted meaning. In reality, interpretations can vary between traditions and sources. Claims about precise symbolic meanings should therefore be connected to the particular religious or philosophical context in which they occur.
Its history also illustrates the difference between a symbolic design and the belief system surrounding it. The diagram can be described historically through surviving manuscripts, ritual objects and artistic representations, while its spiritual significance belongs to the traditions of practitioners who use it.
Why the Sri Yantra matters: it shows that understanding a symbol may require studying not only its visual form, but also the ritual practices, philosophical ideas and communities that give that form meaning.
The Ichthys is a fish symbol associated with early Christianity, and its significance is closely connected with the Greek word ichthys, meaning “fish.” The letters of the Greek word were also understood by Christians as forming an abbreviated expression referring to Jesus Christ.
Fish imagery appears in early Christian art and material culture, including inscriptions, burial contexts, lamps and other objects. But the evidence does not support the simple modern story that the fish was universally used as a secret sign by Christians hiding from Roman persecution. Its use was more varied than that.
The fish could carry Christian meaning in connection with Jesus, baptism, food, and biblical stories, depending on the context in which it appeared. This makes the surrounding image or object important when interpreting an example rather than assuming that every fish automatically represented the same idea.
The Ichthys also demonstrates how a visual symbol can work together with language and religious belief. Its significance comes partly from the relationship between the fish image and the Greek word, showing that symbols do not always communicate through visual appearance alone.
Why the Ichthys matters: it shows how historians need to consider image, language, object and context together. A simple shape can become meaningful because of the cultural and religious system in which it is used.
The Dharma Wheel, or Dharmachakra, is one of the most recognisable symbols of Buddhism. It represents the Dharma — the teachings of the Buddha and the path of practice — and became an important visual element in Buddhist religious traditions.
The wheel appears in Buddhist art and material culture across South and Central Asia and later throughout the wider Buddhist world. Its association with the Buddha's teaching is particularly important because the wheel suggests something that is set into motion and carried forward. Early Buddhist traditions also used wheel imagery in connection with the Buddha and the spread of his teachings.
The number and arrangement of the spokes can vary, and later Buddhist traditions have attached different interpretations to particular elements of the wheel. These interpretations should not automatically be treated as one original meaning shared by every Buddhist community or period.
The Dharma Wheel therefore illustrates how a symbol can become part of a larger religious system. Its meaning is connected not only to its circular form, but to Buddhist teachings, stories, practices and artistic traditions.
Why the Dharma Wheel matters: it shows that a symbol's meaning can emerge from its relationship with a belief system and the practices of the people who use it. Understanding the wheel therefore requires more than interpreting its shape; it requires understanding the religious context in which it appears.
The pentagram is a five-pointed geometric form with a long and varied history. It appears in different historical settings, including the ancient Mediterranean and later European traditions, but its meaning was not the same everywhere.
The form was used by different communities for different purposes. In some contexts it had mathematical, philosophical or religious associations; in others it functioned as a decorative or identifying motif. Its appearance on an object therefore does not, by itself, tell us what the people who made or used it believed.
The pentagram also demonstrates how meanings can accumulate over time. Later Christian, esoteric and occult traditions gave the five-pointed form additional interpretations, while modern movements have adopted it for still other purposes. These later meanings should not automatically be projected back onto earlier examples.
Because the pentagram occurs across widely separated periods and cultures, it is particularly important to distinguish visual similarity from historical continuity. Two five-pointed forms may look almost identical while having developed independently and serving completely different purposes.
Why the Pentagram matters: it shows why a symbol's history cannot be reconstructed simply by collecting every known occurrence of a similar shape. To understand a particular pentagram, we need to ask when, where, by whom and for what purpose it was used.
Maya inscriptions can look like collections of decorative symbols, but many of these signs were part of a sophisticated writing and calendrical system. Maya scribes used combinations of signs to record names, titles, events, dates and other information on monuments, ceramics, manuscripts and other objects.
This makes Maya writing an important reminder that not every historical symbol was created primarily to represent an abstract idea. Some signs functioned as part of a written language, while others were used within calendrical systems. Their meaning depends on how they were combined and the context in which they appeared.
The surviving evidence has also changed how these signs are understood. Maya writing was once widely misunderstood, but the gradual decipherment of the script has allowed researchers to read many inscriptions and connect signs with specific words, sounds, names and dates. This provides a much stronger basis for interpretation than simply comparing the shapes of individual glyphs.
At the same time, not every sign or inscription is equally easy to interpret. Damage, unusual spellings, incomplete texts and differences between periods and locations can leave questions unresolved.
Why Maya Writing & Calendar Signs matter: they show that context can transform how we understand a visual sign. A shape that looks like a standalone symbol may actually be part of a larger writing system, and its meaning may only become clear when we examine the signs around it.
The spiral is one of the most widespread visual forms in human history. It appears in prehistoric carvings, pottery, architecture, manuscripts and decorative art across many different regions. But its widespread appearance does not mean that all spirals belonged to the same tradition or carried the same meaning.
One of the best-known examples is the triple spiral carved at Newgrange in Ireland, created during the Neolithic period. The motif survives as part of the monument's decorated stonework, but there is no written explanation from the people who created it telling us what the design meant.
Other spiral motifs appear in later cultures and very different historical settings. Some have been interpreted as representing movement, cycles, nature or continuity, but these interpretations cannot automatically be applied to every spiral found in the archaeological record.
The spiral therefore presents a particularly useful problem for historical interpretation. A visual form may recur because people independently arrived at a similar design, because techniques or ideas spread between communities, or for reasons we can no longer determine.
Why the Spiral matters: it shows that similarity is not proof of connection. Before linking two symbols across cultures or periods, we need evidence of historical contact, transmission or shared tradition. Sometimes the most responsible conclusion is simply that the evidence does not allow us to know.
Looking across these 15 examples, some broad patterns begin to emerge. But they are not rules that can be applied to every symbol.
Many symbols are connected with ideas that matter deeply to human communities — life, protection, belief, identity, authority, knowledge and the natural world. Some became part of religious practice, while others were used in writing, decoration, ritual objects or systems of visual communication.
Another pattern is that symbols do not remain fixed. A visual form can be carried into a new period, adopted by another community, or given a different meaning. Some traditions continued as living practices, while others survive mainly through archaeological remains and historical records.
The collection also shows why similarity needs to be treated carefully. The same kind of shape can appear in different places without proving that one culture borrowed it from another. The triple spiral at Newgrange, for example, cannot simply be treated as the beginning of every later three-part spiral tradition. Likewise, the pentagram and spiral appear in many settings without having one universal historical meaning.
The evidence available to historians also varies. Some symbols can be connected to written words or inscriptions, while others survive mainly as images or objects whose original meanings were never recorded. In some cases, we can be fairly confident about how a symbol was used. In others, interpretation remains open.
Taken together, these examples suggest a useful starting point for studying ancient symbols:
Look beyond the shape. Ask about the people, the period, the place, the object and the evidence.
That is where the history of a symbol begins.
Human beings often recognise patterns quickly. When we see similar symbols in different cultures, it is tempting to assume that one must have influenced the other. Sometimes that may be true. But similar appearance alone is not evidence of historical connection.
The triple spiral at Newgrange and later three-part spiral or triskelion designs are a useful example. They may look related to a modern viewer, but they belong to very different historical settings. Without evidence of contact, transmission or continuity, we cannot simply assume that one developed from the other.
The same problem appears with other recurring forms. Spirals, hands, wheels, geometric patterns and other visual shapes can arise independently because people in different societies may use similar ways of organising lines, movement and space.
Historical interpretation therefore requires more than comparison of shapes. We need to ask whether there is evidence of contact between communities, movement of ideas, continuity of use, or a documented tradition connecting the examples.
When that evidence is absent, the careful conclusion is not that two symbols are connected — but that their similarity may be coincidental or may have more than one possible explanation.
Why this matters: recognising similarity is only the beginning of interpretation. The historian's task is to determine whether the evidence supports a connection, leaves the question open, or points towards independent development.
A symbol does not necessarily keep the same meaning throughout its history. Meanings can change as symbols move between cultures, religious traditions, languages and historical periods.
Sometimes the change is gradual. A symbol may begin in one context and later acquire additional associations. In other cases, a community may adopt an existing visual form and give it a meaning shaped by its own beliefs or practices. The symbol may look familiar while the ideas attached to it have changed.
The swastika provides one of the clearest examples. The form has a much longer history in several cultural traditions, including South Asia, where it remains associated with auspiciousness and well-being. Its adoption by the Nazi movement in the twentieth century created a powerful new political association that profoundly changed how the symbol is understood in many parts of the modern world.
Other examples in this collection show less dramatic forms of change. The pentagram has been used in different philosophical, religious and esoteric traditions, while the Hamsa has developed meanings within different cultural and religious settings. These histories cannot be reduced to one original meaning that remained unchanged.
This is why historians should be careful when describing a symbol as though it has one timeless definition. A symbol has a history, and that history can include reinterpretation, adaptation, new uses and sometimes deliberate redefinition.
Why this matters: when we encounter a familiar symbol today, we should ask not only “What does it mean?” but also “When did it acquire that meaning, and in what context?”
Symbols can be valuable historical evidence, but they do not always provide a complete explanation of themselves. A surviving symbol can show us what people made, where it was used and sometimes how it was used, while leaving questions about its original meaning unanswered.
The context around a symbol is therefore essential. Historians may consider its date, location, material, surrounding images, inscriptions, objects and associated texts. A symbol appearing on a protective amulet tells us something different from the same shape appearing in a manuscript, monument or decorative pattern.
The type of evidence also matters. A written source may explain a symbol directly, while an archaeological object may provide evidence only through its context and repeated use. Sometimes several types of evidence support the same interpretation. In other cases, the surviving evidence is incomplete or open to competing explanations.
This means that interpreting a symbol involves distinguishing between what the evidence shows, what historians infer from that evidence, and what remains uncertain. A plausible interpretation is not necessarily a proven one.
The 15 examples on this page illustrate this difference repeatedly. Some meanings are supported by written language or clearly documented use. Others can be understood only through archaeological and visual evidence. And in some cases, we simply cannot know with confidence what the original creators intended.
Why this matters: reading symbols as historical evidence means resisting the temptation to give every familiar shape a fixed meaning. The goal is not to eliminate uncertainty, but to understand how much the surviving evidence allows us to say.
The 15 examples on this page are a starting point for thinking about how symbols are interpreted through history. Understanding them more deeply means moving beyond recognition and asking how historians use surviving evidence to build and test interpretations.
WeaversNest is developing a documentary and accompanying academic resource on ancient symbols. These will take the questions introduced here further, exploring historical evidence, interpretation and uncertainty in greater depth.
Coming soon: the documentary and academic resource will be available on WeaversNest.
