Pronunciation

  • Classical: [ˈɔ.nyks][1]
  • Ecclesiastical: [ˈɔː.niks][1]

Forms

onyx m (genitive onychis or onychos); third declension[1] It is masculine, but feminine in Pliny the Elder and Martial.[2][3] Manuscripts often spell it ⟨onix⟩, and sometimes ⟨honyx⟩.[4]

Etymology

It is borrowed from Ancient Greek ὄνυξ (ónux, “nail, claw; onyx”),[2][5][1] the stone being named after the colour of a fingernail.[3] Köbler traces the Greek word to Proto-Indo-European *h₃n̥gʷʰ- (“nail, claw”).[6]

Earliest recorded meaning

It is first found in Catullus, of a jar of onyx that pours out welcome offerings of perfume.[2][7]

Semantic evolution

The word named a prized stone, probably a kind of marble: Pliny the Elder says it was once thought to grow only in the mountains of Arabia and was first made into drinking cups, Lucan and Martial have floors of onyx, and Statius a temple adorned with it.[2][3] From the material it passed to a box or jar of onyx for ointments, as in Horace's “small onyx of nard” and in Propertius and Martial.[2][3]

Pliny also uses it for a many-coloured gem, describing black Arabian onyxes with white bands, and for a kind of razor shell.[2][3] Medieval glossaries keep the Greek sense “fingernail” or “claw”, and medieval writers credited the gem with powers, such as disturbing sleep.[8]
