Forms

lībrātor m (genitive lībrātōris); third declension[1][2]

Etymology

It is from Latin lībrō (“to level, balance”) + -tor.[1][3] That verb comes from lībra (“balance; pound”),[4] which de Vaan traces to Proto-Italic *leiþra- (“pound”); the root is unidentified, and he notes that the name of a weight or coin may well be a loanword.[5]

Earliest recorded meaning

Köbler first records it in Cato,[6] in De agri cultura, in the sense of a leveller.[7]

Semantic evolution

The leveller worked especially with a water level:[7][2] Frontinus uses the word in his work on the aqueducts, and Pliny the Younger asks for a leveller or an architect to be sent to find out whether a lake lies higher than the sea.[7][2] The Theodosian Code speaks of water levellers (aquae lībrātōrēs).[2]

Tacitus twice names soldiers who hurl missiles beside the slingers;[7][2] Gaffiot takes them as men who worked war engines.[8] The DMLBS notes that Late Latin used the word for a surveyor, and in British medieval Latin it meant one who weighs or considers, said of God.[9]

Timeline

  • 234–149 BC – Cato uses it of a leveller.[7][6]
  • c. 100 AD – Frontinus uses it in his work on the aqueducts.[7][6]
  • 98–115 AD – Tacitus uses it of soldiers who hurl missiles.[7][6]

Meanings

Noun

  1. A leveller, surveyor who takes levels (especially for water channels).[1][7][2]
  2. A soldier who hurls missiles by hand.[7][2]
  3. (Medieval Latin) One who weighs or considers (said of God).[9]

Usage notes

In both passages of Tacitus the text has lībrītor, which Georges treats as a by-form; he distinguishes the lībrātor, who hurled stones with a strap, from the funditor, who used a sling.[2]
