語源

Learned borrowing from Latin rōstrum (“beak, snout”), from rōd(ō) (“gnaw”) + -trum, from Proto-Indo-European *Hreh₃d- + *-trom. The pulpit sense is a back-formation from the name of the Roman Rōstra, the platforms in the Forum where politicians made speeches. The Rōstra were decorated with (and named for) the beaks (prows) of ships from naval victories.

They pushed at each other with their rostra, and clawed and thumped, apparently in the greatest rage, although their coats of mail must have saved both from injury.

     Sīve ego, quod nōlim, longīs cōnsūmptus ab annīs,

     sīve per inmēnsās iactābor naufragus undās,
         nostraque longinquus viscera piscis edet,
     sīve peregrīnae carpent mea membra volucrēs,
         sīve meō tinguent sanguine rōstra lupī,
     sīve aliquis dignātus erit suppōnere terrae
         et dare plēbēiō corpus ināne rogō,

     Whether I shall be consumed by the long years, which I do not want,
         whether I shall be set free by a death caused by a hand,
     whether I shall be thrown shipwrecked about the immense waves
         and a fish from far away lands my guts will eat,
     whether wandering birds my limbs should rip,
         whether wolves will stain their snouts with my blood,
     whether someone will be dignified to lay on the ground
         and give to a plebeian pyre my useless body,
     whatever I shall be, I shall strive to break from the banks of the Styx
         and I'll hold my icy hands in your face as an avenger.
