Forms

ātrāmentum n (genitive ātrāmentī); second declension[1]

Etymology

It is from Latin āter (“black”) + -mentum.[2][1][3] Isidore of Seville explains that it is called ātrāmentum because it is black.[3]

Earliest recorded meaning

It is found first in Plautus' Mostellaria, meaning a black colouring: one might as well try to whiten ivory with blacking.[2][4][5]

Semantic evolution

It named any black liquid or substance used for colouring, a black pigment or blacking:[2][6] Horace notes that inks leave a mark and a stain when handled, and Vitruvius and Pliny the Elder describe its use by painters and for walls.[2][7] Pliny counts it among the artificial colours.[2]

Its commonest use was for writing ink (ātrāmentum librārium or scrīptōrium):[2] Cato already says that Antiochus wages war with pen and ink, and Cicero writes with a pen and ink well mixed.[2][7][4] Ātrāmentum sūtōrium, “shoemaker's black”, was a solution of copper sulphate used to blacken leather and as a medicine,[2][7] and Cicero jokes about a man thought to have been acquitted by it.[7] The black fluid of the cuttlefish was ātrāmentum sēpiae, with which Cicero says the cuttlefish protects itself.[2][6]

In the Vulgate the Third Letter of John speaks of writing with ink and pen,[6] and in Ecclesiastical Latin it means ink.[8]
