The Rostra in the Forum Romanum, July 2012

The Rōstra (Italian: Rostri) was a large platform built in the city of Rome that stood during the republican and imperial periods. Speakers would stand on the rostra and face the north side of the comitium towards the senate house and deliver orations to those assembled in between. It is often referred to as a suggestus or tribunal the first form of which dates back to the Roman Kingdom, the Volcanal.

It derives its name from the six rōstra (plural of rōstrum, a warship's ram) which were captured during the victory at Antium in 338 BC and mounted to its side. Originally, the term meant a single structure located within the Comitium space near the Forum and usually associated with the Senate Cūria. It began to be referred to as the Rōstra Vetera ("Elder Rōstra") in the imperial age to distinguish it from other later platforms designed for similar purposes which took the name "Rōstra" along with its builder's name or the person it honored.

Magistrates, politicians, advocates and other orators spoke to the assembled people of Rome from this highly honored, and elevated spot. Consecrated by the Augurs as a templum, the original Rostra was built as early as the 6th century BC. This Rostra was replaced and enlarged a number of times but remained in the same site for centuries.

Julius Caesar rearranged the Comitium and Forum spaces and repositioned the Senate Curia at the end of the republican period. He moved the Rostra out of the Comitium when the Curia Cornelia was dismantled. This took away the commanding position the curia had held within the whole of the forum, having advanced extremely close to the Rostra during its last restoration. Augustus, his grand-nephew and first Roman emperor, finished what Caesar had begun, as well as expanded on it. This "New Rostra" became known as the Rostra Augusti. What remains in the excavated forum today, next to the Arch of Septimus Severus has endured several restorations and alterations throughout its historical use. while a few different honorary names are attributed to those restorations, scholars, archeologist and the government of Italy recognise this platform as the "Rostra Vetera" encased inside the "Rostra Augusti".

The term "Rostrum", referring to a podium for a speaker is directly derived from the use of the term "Rostra". One stands in front of a Rostrum and one stands upon the Rostra. While, eventually, there were many rostra within the city of Rome and its republic and empire, then, as now, "Rostra" alone refers to a specific structure. Before the Forum Romanum, the Comitium was the first designated spot for all political and judicial activity and the earliest place of public assembly in the city. A succession of earlier shrines and altars is mentioned in early Roman writings as the first suggestum. It consisted of a shrine to the god Volcan, that had two separate altars built at different periods. This early Etruscan mundus altar originally sat in front of a temple that would later be converted into the Curia Hostilia.

During the late Republic the rostra was used as a place to display the heads of defeated political enemies. Gaius Marius and consul Lucius Cornelius Cinna captured Rome in 87 BC and placed the head of the defeated consul, Gnaeus Octavius, on the Rostra. The practice was continued on by Sulla and Mark Antony, who ordered that Cicero's hands and head be displayed on Caesar's Rostra after the orator's execution as part of the Proscription of 43 B.C.

Caesar spoke from the Rostra in 67 BC in a successful effort to pass, over the opposition of the Senate, a bill proposed by the tribune Aulus Gabinius (the Lex Gabinia) creating an extraordinary command for Pompey to eliminate piracy in the Mediterranean. Brutus and Cassius spoke from the Rostra to an unenthusiastic crowd in the Forum after the assassination of Caesar in 44 BC. Millar comments that during the late Republic, when violence became a regular feature of public meetings, physical control and occupation of the Ro
