Pronunciation

  • Ecclesiastical: [ˈklɛp.si.dra][1]

Forms

clepsydra f (genitive clepsydrae); first declension[1]

Etymology

It is borrowed from Ancient Greek κλεψύδρα (klepsúdra, “water clock”).[2][3][1] The Greek word is made from the stem of κλέπτω (kléptō, “to steal, to hide”) and ὕδωρ (húdōr, “water”).[4][5]

Earliest recorded meaning

In Cicero it is the water clock that limited the time of speakers: he says of Pericles that no declaimer had taught him to bark at the clepsydra.[2][6]

Semantic evolution

It was a vessel with a bottom pierced like a sieve, from which the water fell drop by drop.[7] Pliny the Elder records that Scipio Nasica first brought the water clock to Rome from Greece.[7] In the courts each speaker was given a set number of clepsydrae, so the word also became a measure of time, the time one clock took to empty; in Pliny the Younger and Martial a speaker asks for, or is granted, so many clepsydrae.[2][6][8]

Medieval Latin kept the water clock and added the senses of a spigot or tap, and a funnel.[9][10][11]
