Horology

/hɒˈrɒlədʒi/noun

The measurement of time and the making of clocks.

The Greek roots

ὥρα
hṓra
hour, season, right time
+
λόγος
lógos
study, account

Literally: study of hours

The story of the word

ὥρα began as a season or the right moment, and the Ὧραι were goddesses of the seasons before anyone counted hours; fruit picked at the right time was ὡραῖος, which drifted into meaning beautiful and is still the ordinary Greek word for lovely. Equal hours came late, out of Egyptian and Hellenistic astronomy, because a daylight hour defined as a twelfth of the day is much longer in June than in December. The horoscope is a close relative: ὡροσκόπος, the hour-watcher, the sign observed rising at the moment of a birth.
