Lucius Marcius Philippus was a Roman politician who was elected suffect consul in 38 BC. He was step-brother to the future emperor Augustus, as well as his uncle (his wife's sister was Atia Balba, mother of Augustus).
Life
A member of the plebeian branch of the Marcia family, Philippus was the son of Lucius Marcius Philippus, the consul of 56 BC. By 50 BC, he had possibly become an Augur, one of the priests of ancient Rome.Broughton, pg. 254 In 49 BC he was elected as Plebeian Tribune, where he vetoed the proposal to send Faustus Sulla, Pompey’s son-in-law, as propraetor to Mauretania, to persuade kings Bocchus II and Bogud to side with Pompey and abandon Julius Caesar.Holmes, pg. 2; Broughton, pg. 258 In 44 BC he was elected praetor, and although he was granted a province to administer after his term had finished, he refused to accept the validity of the allotment of provinces agreed to in a Senate meeting of November 28, 44 BC.Broughton, pg. 321
With his father's marriage to Atia, he became step-brother to Gaius Octavius, Julius Caesar's heir. His father used his influence to help Philippus to obtain the consulate as one of the suffect consuls of 38 BC; nevertheless, during his consulate Philippus did not declare himself openly for his step-brother in his rivalry with Mark Antony.Syme, pg. 229; Broughton, pg. 389 By 35 BC, he was appointed the proconsular governor of one of the two provinces of Hispania.Broughton, pg. 407; Syme, pg. 239 After serving there for two years, he returned to Rome, where he was awarded a triumph which he celebrated on April 27, 33 BC for his actions while governor.Broughton, pg. 415; Syme, pg. 241 With the spoils of his victories, he restored the Temple of Hercules Musarum in the Portico of Octavius, thereafter known as the Portico of Philippus ().Syme, pg. 241; Broughton, pg. 415 Augustus restored the adjacent Portico of Metellus, rededicating it as the Portico of Octavia.
Philippus did not appear to have any living sons to succeed him.Syme, pg. 496 Philippus married Atia, daughter of Julia Minor and Marcus Atius Balbus and maternal aunt of Augustus. (Limited Preview of this page at Google Books) They had a daughter, Marcia, who later married Paullus Fabius Maximus. Marcia had one son and possibly one daughter: Paullus Fabius Persicus and Fabia Numantina, who may have been the daughter of Maximus's brother Africanus Fabius Maximus.
