Gaius Caecilius Metellus Caprarius (born c. 160 BC) was a consul of the Roman Republic in 113 BC with Gnaeus Papirius Carbo. He served under Scipio Aemilianus in Numantia around 133 BC. He was praetor in 117 BC. His proconsulship in Thrace in 112–111 BC earned him a triumph. He was censor in 102 BC with his cousin, Quintus Caecilius Metellus Numidicus.
The Temple of Cybele or Temple of Magna Mater was Rome's first and most important temple to the Magna Mater ("Great Mother"), who was known to the Greeks as Cybele. It was built to house a particular image or form of the goddess, a meteoric stone brought from Greek Asia Minor to Rome in 204 BC at the behest of an oracle and temporarily housed in the goddess of Victory's Palatine temple. The new temple was dedicated on 11 April 191 BC, and Magna Mater's first Megalesia festival was held on the temple's proscenium.
The temple was sited on the high western slope of the Palatine, overlooking the valley of the Circus Maximus and facing the temple of Ceres on the slopes of the Aventine. It was accessible via a long upward flight of steps from the flattened area or proscenium below, where the goddess's festival games and plays were staged. The goddess's altar was visible both from the proscenium and the temple's interior. The original temple burned down in 111 BC, and was restored by one Metellus, possibly Gaius Caecilius Metellus Caprarius. It burned on a further two occasions in the early Imperial era, and was restored each time by Augustus; his second rebuilding was probably the more sumptuous of the two.
Gnaeus Papirius Carbo was a Roman military general and politician in 113 BC, together with Gaius Caecilius Metellus Caprarius.
