Forms

pēnicillus m (genitive pēnicillī); second declension[1] Also neuter pēnicillum and pēnicillis;[1] manuscripts of Vegetius write penicell-.[2]

Etymology

It is a diminutive from Latin pēniculus (“brush”),[2] or, as the OLD analyses it, from Latin pēnis + -cillus.[1] Cicero himself explains it: the ancients called a tail ⟨penis⟩, and the brush was named from its likeness.[1][2] For the further origin of pēnis, see that word.[3]

Earliest recorded meaning

It is first found in Cicero (81–43 BC),[4] meaning a paintbrush; in a letter he explains the word from penis, the old word for a tail.[1]

Semantic evolution

From the painter's brush Cicero also used it for the art of painting itself, saying that a supreme grief could not be imitated with the brush.[1] Celsus uses it in medicine for a swab or pad soaked in cold water,[1] Pliny the Elder for the softest kind of sponge,[1] and an inscription from Britain names an eye-salve with it.[1]
