What is a horologe?
A horologe is a timepiece: any instrument that tells the hour. A sundial is a horologe. A tower clock is a horologe. The watch on your wrist, if you still wear one, is a horologe. The word doesn't say how the hour is told — only that it is told.
It comes from the Greek hōra, hour, and legein, to tell or to say. Put together they make horologion, an hour-teller, which walked into Latin and then into English. The horologe spelling has been in English dictionaries for centuries, and it keeps the silent-ish ending of its French middleman, horloge. You say it like this: HOR-uh-loj, three beats, stress the first, and the last syllable rhymes with "lodge".
Horologe, horology, horologist
Three words from the same root, three different jobs.
Horology is the craft and study of timekeeping — the whole field, from pendulum physics to the finishing on a balance spring. A horologist is someone who practises it: a clockmaker, a watchmaker, the person a museum calls when the longcase on the stairs stops. And a horologe is simply the thing itself, the instrument, the clock on the wall of the word.
You'll meet all three in old books before you meet them anywhere else. Writers used horologe when they wanted the clock to sound like an instrument rather than furniture — the tower clock in a distance, the dial on a sundial, anything that stood between the hour and the reader's guess of it.
Why an app took the word
Horologe — the app this journal belongs to — is a desk clock for the Mac that strikes the hour. Four faces drawn in code, five bells computed from a bell's own partial structure the moment they sound, quiet hours from ten in the evening to eight in the morning. It costs $5.99 once, on the Mac App Store.
The word fits because the oldest part of the job is the part most clocks have dropped. For centuries, telling the hour meant saying it — a bell counted out three strokes for three o'clock, to everyone in earshot, whether or not anyone was watching. A horologe that keeps the time but keeps it to itself is doing half the job. The dial is the record; the bell is the telling.
So that's the definition, and the pronunciation, and the reason. If you'd like the hour told to you rather than shown at you, the clock is on the front page — you can strike all five bells there without buying anything.
