Etymology

from Latin Rostra "the speaker's platform in the Forum," from rostra, plural of rostrum "ship's beak"

Word Origin

Rostrum, a "raised platform for speakers," goes back to the collecting of war souvenirs by the ancient Romans. Warships in those days had pointed beams, called "beaks," sticking out from the bows. They were used to ram and sink enemy ships. To celebrate a great naval victory, the Romans gathered the beaks of the losers' ships. They hung them in back of the speaker's platform in the Forum in Rome. The Latin word for the ship's beak was rostrum. The plural, rostra, soon came to be used for the speaker's platform. In time rostra came to be used for any speaker's platform, not just one decorated with the beaks of ships. In the 18th century English began using the Latin singular form rostrum to mean "a speaker's platform."
