      What produce of beasts, then, or what commodity could be obtained, if men didn't assist? For those that first found out what use we can have from each beast, were surely humans, and we cannot in the present either pasture them or break them in or take care of them or obtain the timely fruit from them without the labour of humans; and by the same are killed those who do harm and captured those that can be of use.

        Then, with the civil unrest quietened, he charged Cornelius Dolabella, former consul who had triumphed, with extortion; with him acquitted, he resolved to leave for Rhodes, to escape the hate as well as to pay attention in rest and recreation to Apollonius Molon, then the most distinguished teacher of speaking.

    1. (by extension) any kind of worker
      • c. 77 CE – 79 CE, Pliny the Elder, Naturalis Historia 33.72–73:
        Et tamen in silice facilior existimātur opera; est namque terra ex quōdam argillae genere glāreā mixta—gangadiam vocant—prope inexpugnābilis. Cuneīs eam ferreīs adgrediuntur et īsdem malleīs, nihilque dūrius putant, nisi quod inter omnia aurī famēs dūrissima est. Perāctō opere cervīcēs fornicum ab ultimō caedunt. Dat signum rīma, eamque sōlus intellegit in cacūmine eius montis vigil. Hic vōce, nūtū ēvocārī iubet operās pariterque ipse dēvolat. Mōns frāctus cadit ab sēsē longē fragōre quī concipī hūmānā mente nōn possit, aeque et flātū incrēdībilī. Spectant victōrēs ruīnam nātūrae. Nec tamen adhūc aurum est nec sciēre esse, cum fōderent, tantaque ad perīcula et inpendia satis causae fuit sperāre quod cuperent.
        And still the work is considered to be easier in flint; for there is earth, consisting of some kind of clay, mixed with gravel—they call it gangadia—almost impenetrable. They approach it with iron wedges and with the same hammer machines [as above], and they consider nothing harder, save for the fact that hunger for gold is the hardest among all things. With the work done, they cut down the supports of the arched roofs beginning from the last one. A fissure gives the sign, and only the watchman in the peak of that mountain notices it. He orders by voice and by gesture the miners to be called outside, and rushes down in the same manner. At a distance, the mountain, broken, falls by itself with a crash which cannot be conceived by the human mind, and with an incredible blast as well. The victors watch the ruin of nature. And the gold is not even there yet, nor did they know whether there was any when they were digging, and hoping for what they desired was enough of a reason to go through all these dangers and expenses.
    2. (derogatory, politics) hired aider, tool, rowdy
      • c. 69 CE – 122 CE, Suetonius, De vita Caesarum 2 3.period1:
        C. Octāvius pater a prīncipiō aetātis et rē et existimātiōne magnā fuit, ut equidem mīrer hunc quoque ā nōnnūllīs argentārium atque etiam inter dīvīsōrēs operāsque campestrēs prōditum; amplīs enim innūtrītus opibus honōrēs et adeptus est facile et ēgregiē administrāvit.
        The father Gaius Octavius was from the beginning of his age of great wealth as well as reputation, so that I wonder that he too is alleged by some to have been a money-changer and even among the electoral bribe distributors and aiders in the Campus Martius; for, brought up with ample riches, he obtained honours with ease as well as administering them excellently.
  10. deed, activity, effort
    • 59 BC–AD 17, Titus Livius, Ab urbe condita libri 41.4.6:
      Ante omnēs īnsignis operā fuit C. Popilī equitis; Sabellō cognōmen erat. Is pede sauciō relictus longē plūrimōs hostium occīdit.
      More distinguished than others in deeds was Gaius Popilius the knight; Sabello was his cognomen. He, left behind with a wounded leg, killed the most enemies by far.
  11. handiwork
    • c. 209 BCE, Plautus, Asinaria 2.4.18–19:
      Iussīn, sceleste, ab iānuā hoc stercus hinc auferrī?
      Iussīn columnīs dēicī operās araneōrum?
      Didn't I order, you scoundrel, this dung to be carried away from the door?
      Didn't I order the handiwork of spiders to be removed from the columns?

Usage notes edit

The word, in its “spare time” meaning, is frequently used in the ante-classic period, and especially by Plautus, in the locution operae esse, meaning 'to be worth the time'. Later on, it is characteristic of Livy's style and of the archaising tendencies of Silver Latin.
