Why Does the Armenian Alphabet Look More Like Ethiopian Geez Than Greek?

The Short Answer

A computational shape analysis found that the Armenian alphabet is geometrically closer to the Ethiopic Geez script than to Greek — not culturally or historically, but purely in the mathematical structure of its letter shapes.

What the Computer Actually Measured

Researchers fed the letter shapes of world writing systems into mathematical algorithms — specifically Fourier descriptors and skeletal graph analysis — to strip every character down to its pure geometric signature. These tools remove all human bias: no cultural context, no historical assumptions, just raw shape data. When the results came back, Armenian letters clustered more closely with Geez, the ancient script of Ethiopia and Eritrea, than with Greek. That finding was unexpected enough to demand explanation.

The Man Who Built the Armenian Alphabet

Most writing systems evolved gradually over centuries, with no single author and no precise birth date. The Armenian alphabet is a rare exception. In 405 CE, a monk named Mesrop Mashtots sat down and designed the script from scratch — one of the only writing systems in recorded history with a known, single-author origin and an exact year of creation.

Mashtots built 38 letters, deliberately exceeding Greek’s 24 and Latin’s 26. His goal was phonetic completeness — a letter for every sound in the Armenian language. He succeeded. The script has been in continuous use for over 1,600 years. And yet the shapes he chose, apparently from his own creative mind, echo a writing system from the Horn of Africa that he almost certainly never encountered.

Armenian and Geez Are Structurally Different Systems

Here is what makes the geometric similarity even stranger: Armenian and Geez are not even the same type of writing system. Armenian is a true alphabet, where consonants and vowels are represented by separate, equal letters. Geez is an abugida (sometimes called a syllabary), where each character represents a consonant with a vowel inherently baked in — and the vowel is modified by altering the shape of the base consonant.

They operate on entirely different logical principles. And yet, when you ignore the logic and measure only the shapes, they converge. Two systems built on different continents, in different centuries, for different language families, ended up drawing from a surprisingly similar visual vocabulary.

What This Suggests About the Human Brain and Writing

The most provocative interpretation of this finding has nothing to do with historical contact or cultural diffusion. Instead, it points inward — toward the human visual and motor system itself.

Cognitive scientists have long noted that writing systems across the world tend to favor shapes that appear in the natural environment: junctions, curves, and line configurations that the human visual cortex is already wired to detect efficiently. This is sometimes called the “neuronal recycling” hypothesis — the idea that the brain doesn’t invent writing from nothing, but repurposes existing visual-recognition circuits.

If that hypothesis is correct, then independent inventors in different parts of the world might converge on similar shapes not because they copied each other, but because they were all working with the same biological hardware. Mesrop Mashtots, designing in Armenia in 405 CE, and the scribes who developed Geez in the Ethiopian highlands, may have been drawing from the same deep reservoir of shapes that the human brain finds natural to produce and recognize.

Alphabets Invented or Remembered?

The Armenian–Geez comparison forces a quiet but radical question: how much of any alphabet is truly invented, and how much is retrieved from something older — something encoded not in culture, but in the structure of human perception itself? Scripts may look like history. But underneath, they may be anatomy.
