The word 'hieroglyph' encodes a Greek interpretation of one of the world's most visually striking writing systems — and in doing so, it preserves a remarkably accurate ancient insight alongside centuries of profound misunderstanding.
When Greek travelers, merchants, and soldiers encountered Egyptian temples and tombs, they were confronted with walls covered in elaborate pictorial symbols: birds, eyes, serpents, hands, water, reeds, and geometric forms arranged in elegant columns and rows. Herodotus, visiting Egypt in the fifth century BCE, used the phrase 'hierà grámmata' (sacred letters) to describe them. The more specific compound 'hieroglyphikà grámmata' — literally 'sacred carved letters' — appeared soon after, combining 'hierós' (sacred) with 'glýphein' (to carve or engrave).
The Greek coinage was perceptive in one crucial respect. The Egyptians themselves called their script 'medu netjer,' meaning 'words of god' or 'divine speech.' The script was believed to have been invented by Thoth, the ibis-headed god of wisdom and writing, and its use was closely associated with temples, tombs, and priestly functions. In this sense, the Greeks were right
But the Greeks were wrong about almost everything else. They assumed — and later Greek and Roman writers elaborated the assumption into an entire intellectual tradition — that hieroglyphs were purely symbolic or allegorical, that each picture represented an idea or philosophical concept rather than a sound. This misunderstanding was codified in the 'Hieroglyphica' attributed to Horapollo, a late antique text that offered fanciful symbolic interpretations of individual signs. A hieroglyph showing a hare, for example, was
This symbolic interpretation dominated European thinking about hieroglyphs for over a thousand years. Renaissance scholars, fascinated by Egyptian antiquities, studied Horapollo and produced increasingly elaborate allegorical readings. Athanasius Kircher, the great seventeenth-century polymath, published volumes of hieroglyphic 'translations' that were entirely invented. The obelisks brought to Rome
The breakthrough came in 1822, when Jean-François Champollion deciphered the Rosetta Stone and demonstrated that hieroglyphs were primarily phonetic — they represented sounds, not ideas. Most hieroglyphic signs functioned as consonantal letters or syllables, and the script could be read aloud as language. The pictorial nature of the signs was largely incidental to their phonetic function: the owl sign did not mean 'owl' or 'wisdom' in most contexts; it represented the consonant 'm.' Champollion's achievement
The word 'hieroglyph' itself was back-formed from the adjective 'hieroglyphic' in the late sixteenth century. English borrowed the Latin form 'hieroglyphicus' during the Renaissance, and the noun 'hieroglyph' was created by dropping the suffix — a common English word-formation pattern. The shorter form 'glyph,' meaning any carved or inscribed symbol, was extracted even later and has become standard in typography and computing, where a 'glyph' is any visual representation of a character.
The Greek root 'glýphein' (to carve) produced a rich family of English words. 'Petroglyph' (a carving on rock), 'anaglyph' (a carved ornament in low relief), and 'triglyph' (an architectural element with three vertical grooves) all share the same root. The companion root 'hierós' (sacred) gave English 'hierarchy' (originally 'sacred rule,' the ranked order of angels), 'hieratic' (priestly, or the cursive form of Egyptian writing used by priests), and 'hierophant' (a priest who reveals sacred mysteries).
In modern usage, 'hieroglyph' has developed a figurative sense: any writing or symbol that is difficult to decipher. To call someone's handwriting 'hieroglyphic' is to say it is illegible — an ironic usage, since actual hieroglyphs, once Champollion cracked the code, turned out to be perfectly readable. The word carries an aura of mystery and antiquity that no synonym can match, a reminder that for most of Western history, the magnificent inscriptions of Egypt were objects of wonder precisely because no one could read them.
