Forms
hydraulicus (feminine hydraulica, neuter hydraulicum); first/second-declension adjective[1][2] Medieval spellings include idraulicus and forms with ydro-.[3][4]
Etymology
It is borrowed from Ancient Greek ὑδραυλικός (hudraulikós, “of the water organ”),[1][5][3] from ὕδωρ (húdōr, “water”) and αὐλός (aulós, “pipe”).[3][6] Within Latin it belongs with hydraulus, the water organ.[7] English hydraulic comes from it through French.[8]
Earliest recorded meaning
Vitruvius is the first to use it: no one, he says, could build “hydraulicas machinas” and similar instruments without a knowledge of music (1.1.9), and he credits Ctesibius with first making them (9.8.4).[7][2][3]
Semantic evolution
Its core use was for the water organ, called machinae or organa hydraulica,[9][2] which Pliny the Elder also ascribes to Ctesibius;[7] the OLD defines it more broadly, of machines worked by water flowing through pipes.[1] Suetonius and Ammianus Marcellinus write of organa hydraulica too.[2][9] Medieval writers kept it for organs: the Annals of Fulda, under the year 826, tell of a priest from Venice who built a water organ at Aachen,[4] William of Malmesbury writes of organa hydraulica,[10] and Osbern of Gloucester glosses it “sweet and sonorous”.[10] As a neuter noun it named a water-driven instrument.[4] Etymonline notes that the Romans extended the Greek term to other water engines.[8]
