stylus

The Greek word stylos meant a pillar or column. The Latin adaptation stilus (note the original spelling with an 'i') referred to a pointed stake or, more specifically, the iron or bone instrument used to write on wax tablets — the everyday writing technology of the Roman world. A wax tablet consisted of a wooden frame filled with a layer of beeswax, into which letters were scratched with the pointed end of the stilus; the flat or rounded opposite end was used to smooth the wax and erase mistakes. The spelling shifted to 'stylus' in later Latin, influenced by the Greek stylos, and this Greek-influenced spelling is the one that survived into English. The original Latin 'stilus' is preserved only in specialist etymological discussions.

The connection between the writing instrument and 'style' — manner of expression — is not metaphorical but direct. Latin stilus came to mean both the tool and the manner of its use: a person's stilus was simultaneously their writing instrument and their way of writing. The transfer from tool to technique was natural in a culture where handwriting was a personal and recognizable art. Roman rhetoric teachers spoke of a good or bad stilus; Cicero praised certain orators for the quality of their stilus. When the word entered English as 'style' in the fourteenth century, the instrument had already been largely displaced by the quill, but the abstract meaning — a distinctive manner of expression — had become dominant. Style and stylus diverged: one named the tool, the other the quality the tool produced.

The Roman wax tablet and its stylus constituted the most widespread everyday writing system in the ancient Mediterranean world. Schoolchildren learned their letters on wax tablets; merchants kept accounts on them; soldiers carried them in the field; lovers sent private notes on them. The ability to erase by smoothing the wax made the tablet a reusable surface — the ancient equivalent of a whiteboard or a draft document. The phrase vertere stilum — 'to turn the stylus' — meant to revise, to erase and rewrite, because the writer literally turned the instrument from its pointed writing end to its flat erasing end. This Roman idiom for revision persists conceptually in every writer's understanding that writing is rewriting.

The word experienced a dramatic technological resurrection in the late twentieth and twenty-first centuries. The stylus returned first as the instrument for personal digital assistants in the 1990s — the Palm Pilot's plastic-tipped stylus that tapped and dragged on a resistive touchscreen. Then it returned more sophisticatedly as the pressure-sensitive stylus for digital art tablets and the Apple Pencil, instruments that translate the pressure and angle of a hand movement into digital marks with the fidelity of a physical pen. The circle from Roman wax tablet to digital glass tablet is remarkably tight: a pointed instrument held in the hand, making marks on a flat surface that can be instantly erased. The technology changed completely; the gesture remained identical. The Greek pillar has become a cylinder of aluminum and silicon, but the hand that holds it moves the same way.
