He was the brother of Publius Minucius Augurinus, who later served as consul in 492 BC.
During his first tenure as consul, he was charged with the consecration of the newly constructed Temple of Saturn in the Roman Forum.
[1][2] Prior to becoming consul Minucius held the quaestorship in 509 BC.
There had been a famine in Rome in the previous year, and in 491 BC a significant quantity of corn was imported from Sicily, and the question of how it should be distributed amongst the Roman citizens, together with tensions arising from the recent secession of the plebs, led to the exile and defection of Gaius Marcius Coriolanus after he unsuccessfully advocated the reversal of the reforms which arose from the secession, including the creation of the Tribune of the Plebs.
[4] He was one of the five ex-consuls sent as envoys to treat with Coriolanus in 488 BC during his march towards Rome.
