Balbus, literally "stammerer", was the name of several Roman families.
Of the Acilii Balbi, one Manius Acilius Balbus was consul in 150 BC, another in 114. To another family belonged T. Ampius Balbus, a supporter of Pompey, but afterwards pardoned by Julius Caesar (cf. Cic.ad Fam. vi. 12 and xiii. 70). We know also of Q. Antonius Balbus, praetor in Sicily in 82 BC, and Marcus Atius Balbus, who married Julia, a sister of Caesar, and had a daughter Atia, mother of Augustus.
The most important of the name were the two Cornelii Balbi, natives of Gades (Cádiz):
Lucius Cornelius Balbus (called Major to distinguish him from his nephew) was born early in the last century B.C. He is generally considered to have been of Phoenician origin.
After Caesar's murder, Balbus seems to have attached himself to Octavian; in 43 or 42 he was praetor, and in 40 consul - an honour then for the first time conferred on an alien.
In 19 Balbus defeated the Garamantes, and on the 27th of March in that year received the honour of a triumph, which was then for the first time granted to one who was not a Roman citizen by birth, and for the last time to a private individual.
Balbus appeared at the Diet of Worms as the ambassador of Louis II of Hungary, and attracted considerable attention by an eloquent discourse in which he protested against the innovations of Luther, and urged upon the assembled princes the
The address which he made on being received by the pope in a public audience, 9 February, 1523, abounded in extravagant rhetoric, but in humanistic circles it was considered a marvel of eloquence.
Balbus remained in Rome for some time, and was there consecrated Bishop of Gurk, 25 March, 1523.
