Quintus Caecilius Metellus Nepos ( – 55 BC) was an ancient Roman politician during the Late Republic. He was a son of Quintus Caecilius Metellus Nepos and served as tribune of the plebs in 62 BC, consul in 57 BC, and the governor of Hispania Citerior from 56–55 BC.
Early in his career, Nepos served under Pompey during the war against the pirates and the Third Mithridatic War. Returning to Rome in 63 BC, he served as a Pompeian ally in the plebeian tribunate. But after Pompey broke with his family on his return to Italy in 62 BC, Nepos became one of Pompey's opponents, especially after the formation of the so-called First Triumvirate in 59 BC. Elected against the wishes of the triumvirs in 57 BC to a consulship, he supported his cousin Clodius against Pompey's ally Milo and opposed Pompey's attempts to secure another military command, but regardless supported the recall of Cicero from exile.
Early career
Nepos' first recorded public activity was to bring charges in 72 BC against Gaius Scribonius Curio, who was a family rival. The trial was squashed when Curio responded with countercharges and both men backed down. Legal manoeuvres of this sort were common in the late republic and indicate growing factionalism through the 70s BC. Metellus Nepos was a lieutenant (legate) of Pompey in the campaign against the pirates in the Mediterranean for 67–66 BC. There, he commanded naval forces and men on the coast from Lycia to Phoenicia. Like his brother, Quintus Caecilius Metellus Celer, he served in the Third Mithridatic War against Mithridates VI of Pontus and Tigranes the Great of Armenia, taking Damascus in Syria in 64 and leaving Pompey's army for Rome the next year to stand for the tribunate as a Pompeian ally.
Nepos was elected in 63 BC for the plebeian tribunate; he served alongside Cato the Younger that year. After his accession to office in December 63, he attacked Cicero – then-consul – for his illegal execution of the Catilinarian conspirators. He tried to indict Cicero on charges of murder, but the senate passed an amnesty for the consul and then threatened to declare any potential prosecutor a public enemy. In January 62 BC, Nepos attempted to force through a bill to recall Pompey from the war against Mithridates to assume command of the war against Catiline's remaining forces in Etruria. In doing so, he ignored the compulsory waiting period between a bill's promulgation and assembly of a vote. Nepos likely heard from his brother – Metellus Celer, then proconsul in Cisalpine Gaul, – that Catiline would imminently be defeated by Antonius Hybrida's forces in northern Italy.
On 3 January 62 BC, he attempted to pass the bill to transfer the command to Pompey over opposition of the senate. Nepos, along with his ally Julius Caesar (then serving as praetor), assembled the tribes at the Forum before the Temple of Castor and Pollux. Cato and one of his allies, another tribune named Quintus Minucius Thermus, forced their way to the front and Cato then "brusquely took a seat between Nepos and Caesar [to prevent] them from communicating privately". When Nepos directed the bill to be read, Cato vetoed it; when Nepos started to read it himself, Cato snatched the draft from his hands; when Nepos started to recite it from memory, Thermus put his hand over the Nepos' mouth to stop him from speaking. A fight accordingly broke out in the Forum. In response to the violence, the senate passed a senatus consultum ultimum against Nepos, forcing him to flee the city to Pompey's camp in the east.
Suetonius and Plutarch then assert that Nepos, Caesar, or both were removed from their offices. This is unlikely; the senate during the republic had no such powers. More contemporaneous sources imply that the senate may have moved to ratify Nepos' departure from the city (tribunes were legally forbidden from leaving the city), which Cato likely objected to. The proposal to send Pompey after the Catilinarians, regardless, became irrelevant when Catiline and his forces were decisively defeated in battle at Pistoria shortly thereafter.
Praetorship and consulship
After Pompey's return to Italy near the end of 62 BC, Pompey divorced his wife Mucia. Doing so "[gave] substance to reports of her infidelity" and broke Pompey's alliance with Nepos and Metellus Celer, Mucia's half-brothers. Nepos then served as praetor in 60 BC. During his term, he passed a law which abolished customs duties in Rome and Italy. The move likely was related to reforms, pursued by the senate in the aftermath of the Catilinarian conspiracy, to buttress support among agricultural exporters and wealthy importers of luxury goods. He shortly thereafter also became an augur.
