What we explore today is, at its core, a correction of a very deep and almost universal illusion: the idea that language and writing are born together. They are not. Language belongs to our biology—human beings speak as naturally as they breathe. Writing, on the other hand, is an invention, a late and deliberate construction, a tool fashioned to capture something that existed long before it. For tens of thousands of years, human beings told stories, recited genealogies, composed poetry, and transmitted entire bodies of knowledge without writing a single sign. The Vedic tradition is one of the most refined examples of this: an immense corpus preserved not by ink or stone, but by memory, rhythm, and sound, with a precision that still astonishes scholars.
When writing finally appears, it does not emerge in a single place or form, but in several centers, each solving the same problem—how to represent language visually—in its own way. From that point forward, two different questions must always be kept distinct. One is the question of origin: where a system comes from, its lineage, its historical descent. The other is the question of structure: how the system works, what units it encodes, whether it represents sounds, syllables, or meanings. Much of the confusion in this field arises from mixing these two.
In terms of structure, the world’s writing systems fall into a small number of fundamental strategies. Some write sounds directly, as alphabets do, representing both consonants and vowels. Others, like the Phoenician system and its descendants in Hebrew and Arabic, write only consonants—what is called an abjad—leaving the reader to supply the vowels from knowledge of the language. Still others operate at the level of the syllable, assigning a sign to units like “ka” or “tu.” And then there are the more complex systems, which do not commit themselves to a single principle but combine several at once. These mixed systems—among them Egyptian hieroglyphs, Maya writing, and cuneiform—are among the most sophisticated inventions of the human mind, because they allow meaning and sound to coexist in a layered, redundant, and often elegant interplay.
It is here that my intuition about the “cartoon-like” nature of certain scripts becomes not naïve, but perceptive. Egyptian hieroglyphs and Maya glyphs do indeed present themselves visually as images—figures, animals, stylized forms that seem almost narrative. But this appearance must be interpreted carefully. In both cases, the images are not mere decoration; they are functional elements of the writing system. A bird may stand for a sound, a word, or a conceptual category. A human figure may function not as a picture of a person, but as a classifier indicating that the word belongs to the domain of human activity. In Maya writing, entire glyph blocks combine multiple elements—some representing whole words, others representing syllables—into compact visual units that must be unpacked according to established conventions. The result is a script that is at once visual and linguistic, aesthetic and systematic.
Yet, despite these similarities, Egyptian and Maya writing differ in their internal logic. Egyptian hieroglyphs rely heavily on consonantal encoding, somewhat akin to an abjad layered with additional devices, whereas Maya writing is predominantly syllabic, constructing words from sequences of syllable signs. Egyptian texts tend to flow linearly, even when arranged artistically, while Maya inscriptions are organized into blocks that must be read in a patterned sequence. The resemblance between them, therefore, lies not in shared origin but in shared solution: two civilizations, separated by oceans and millennia, arrived independently at a hybrid system that merges image and sound.
This distinction between similarity of structure and similarity of origin is crucial. Egyptian hieroglyphs, Mesopotamian cuneiform, Chinese characters, and Mesoamerican scripts such as the Maya all appear to be independent inventions. They are not branches of a single tree but separate trees that happen to bear similar fruit. This is what is meant, in a more technical language, by convergent development: different cultures, confronted with the same problem, discover comparable strategies.
The Indus script sits precisely at the edge of what we know and what we do not. The seals, those small objects bearing an animal motif and a short sequence of signs—have resisted decipherment for over a century. We can describe them, catalogue them, and observe patterns in the signs, but we cannot yet read them. The presence of animals complicates the matter. In Egyptian or Maya contexts, such images would almost certainly be part of the writing itself. In the Indus case, however, we do not know whether the animal is a linguistic sign, a religious symbol, an emblem of identity, or something else entirely. To assert that it is or is not “read” would go beyond the evidence. The correct position is not certainty, but suspension of judgment.
Alongside these complex systems, another, very different development takes place in the eastern Mediterranean. The Phoenician script, emerging in the second millennium BCE, represents a radical simplification. Instead of hundreds of signs combining meaning and sound, it reduces writing to a small set of characters representing consonants. This system proves extraordinarily powerful because of its efficiency and portability. The Greeks adopt it and introduce explicit vowels, creating the first true alphabet. From this innovation flow the Latin script, the Cyrillic script, and most of the writing systems used in Europe today. Here, again, it is essential to separate language from script: Latin, Greek, and Russian are different languages, but their writing systems are historically connected.
By the time we reach the threshold of the Common Era, the world already contains a remarkable diversity of writing systems: the wedge-shaped impressions of cuneiform in Mesopotamia; the carefully carved hieroglyphs of Egypt; the undeciphered signs of the Indus Valley; the logographic tradition of early Chinese writing; the syllabic system of Linear B in the Aegean; the pictorial hieroglyphs of Anatolia; the consonantal alphabets of the Levant; and, across the ocean, the developing scripts of Mesoamerica. These are not stages of a single progression but parallel experiments, each reflecting a different balance between complexity and efficiency, between image and abstraction.
What I began to do—moving from recognizing that two scripts “look alike” to asking how they function, what units they encode, and how they are structured—is the essential shift. It is the difference between seeing writing as ornament and seeing it as a system. Once that shift is made, the field ceases to be a collection of exotic symbols and becomes an intelligible landscape, one in which each script can be located, compared, and understood on its own terms.
And perhaps the most important realization, the one that ties all the rest together, is this: writing is not a natural mirror of language, but a set of ingenious, sometimes beautiful, always revealing compromises—human attempts to capture, with marks on a surface, the living, flowing reality of speech.
On the Cyrillic alphabet
The story begins in the ninth century with two Byzantine brothers, Cyril and Methodius, sent from the Greek-speaking world into Great Moravia, a Slavic polity located roughly in what is now the Czech and Slovak region. Their mission was not merely religious in the narrow sense, but linguistic and cultural: to make Christian teaching accessible in the Slavic tongue rather than imposing Greek or Latin. To accomplish this, they required something that did not yet exist—a writing system capable of representing the sounds of Slavic speech with precision. The solution was the creation of the Glagolitic script, a highly original and almost architectural set of signs, unlike Greek or Latin in appearance, deliberately constructed to encode the phonetic richness of Slavic languages. With this script, they translated liturgical texts into what we now call Old Church Slavonic, establishing a literary language and, more importantly, a method of preserving and transmitting it.
The Moravian phase of this work, however, was politically fragile. After the deaths of the brothers, resistance from Latin-rite clergy and shifting power structures led to the expulsion of their disciples. It is here that the geographic and cultural movement becomes decisive. These students—trained in the new script, in translation, and in liturgical practice—found refuge further south, in the First Bulgarian Empire. There, in centers such as Preslav and Ohrid, their work did not simply continue; it was transformed. Within this new environment, closer to the Byzantine cultural sphere and already accustomed to Greek literacy, the need arose for a script that was at once more practical and more familiar in form. Out of this context emerged the Cyrillic script, not created directly by Cyril himself, but developed by his intellectual heirs. Cyrillic drew heavily on the shapes of the Greek alphabet, supplementing it with additional signs to represent specifically Slavic sounds that Greek could not capture. In this way, the conceptual breakthrough of Glagolitic—the idea of a Slavic literary language—was preserved, while its visual and practical execution was streamlined.
From Bulgaria, Cyrillic spread widely across the Slavic world, eventually reaching Kievan Rus and becoming the foundation of Russian and other Eastern Slavic literacies, while the regions of Great Moravia and later Bohemia came increasingly under Western (Latin) influence and adopted the Latin alphabet instead. Thus, the legacy of Cyril and Methodius unfolds along two diverging paths: one leading to the enduring Cyrillic tradition of the Eastern Orthodox world, the other fading in its original homeland but surviving indirectly through the work carried south by displaced students. The story is therefore not one of a single invention in a single place, but of a transmission interrupted, redirected, and ultimately reconstituted elsewhere—an intellectual lineage that begins in the Slavic lands of Central Europe, is reshaped in Bulgaria, and from there radiates outward across a vast cultural landscape.
The mission of Cyril and Methodius to Great Moravia begins around 863 AD. It is in this period—within just a few years—that the Glagolitic script is created, translations begin, and a Slavic liturgical tradition is established. This initial phase, from roughly 863 to 885, is the entire lifetime of the project under the direct guidance of the brothers themselves. Methodius dies in 885, and almost immediately afterward the political and ecclesiastical situation turns against their work in Moravia. Within a very short time—essentially a matter of a few years—their disciples are expelled.
Great Moravia did not retain either the Glagolitic script or the later Cyrillic script because, at a decisive moment, it was drawn into the Western (Latin) Christian sphere, aligned with Rome and the political influence of the Frankish–German world. After the death of Methodius in 885, the clergy connected to the Papacy and supported by German rulers asserted control, promoting Latin as the sole liturgical and administrative language and, with it, the Latin alphabet. The Slavic liturgy introduced by Cyril and Methodius was suppressed, and their disciples—carriers of the Glagolitic tradition—were expelled.
At the same time, a different trajectory unfolded to the east and south. In the Byzantine sphere, particularly in Bulgaria, the displaced students were received and their work encouraged, because the Eastern Orthodox world accepted the idea of worship in the vernacular. There, the Slavic literary tradition not only survived but was reshaped into the Cyrillic system and spread further into the lands that would become Kievan Rus. Thus, what you see is not a rejection of one script in favor of another for technical reasons, but a civilizational bifurcation: Western Europe, under Papal and German influence, consolidating Latin language and script; Eastern and Southeastern Europe, under Byzantine influence, fostering Slavic liturgy and Cyrillic writing.
From there, the transition south to Bulgaria happens rapidly, in the late 880s. By the end of the ninth century—around 893 AD, under the rule of Tsar Simeon—the intellectual centers in Bulgaria have already absorbed these students and begun reorganizing their work. It is in this environment, within perhaps one or two decades after the expulsion, that the Cyrillic script emerges in a recognizable form, drawing heavily on Greek models but preserving the Slavic linguistic framework established earlier.
So from the creation of Glagolitic in Moravia to the formation of Cyrillic in Bulgaria—you are dealing with roughly: about 30 years, perhaps 40 at most. From first invention to transformation.
And that is the remarkable part: what feels like a slow civilizational evolution is, in this case, the work of essentially one generation and its immediate successors.
After that, the spread is much longer—over the tenth and eleventh centuries into Kievan Rus and beyond—but the creative moment itself is compressed into that brief, intense period between roughly 863 and 900 AD.
