Lucius Caecilius Metellus Diadematus was the second son of Roman politician and general Quintus Caecilius Metellus Macedonicus.
During his consulship in 117 BC he supported the development of roads in Italy and he probably built Via Caecilia. A year later he was Proconsul of Cisalpine Gaul. In 115 BC Diadematus was elected Censor and during his censorship with Gnaeus Domitius Ahenobarbus they expelled 32 senators from the Senate.Cicero, Pro A. Cluentio 191; Livius, Periochae 62; Plutarchus, Marius 5.
He was an opponent of Lucius Appuleius Saturninus and was arrested in 100 BC with Saturninus and other senators when Saturninus tried to forcefully oppose the Senate.Cicero, Pro C. Rabirio perduellionis reo 21.
He lived to see the return of his first cousin, Quintus Caecilius Metellus Numidicus, from exile, and exerted himself to obtain his recall.Cicero, Oratio post reditum in senatu 37.
He is attested as consul, together with his colleague, Quintus Mucius Scaevola Augur, on the sententia Minuciorum, a legal document describing arbitration by Roman officials.
