Quintus Lutatius Catulus
Gaius Atilius Serranus (c. 149 – 87 BC) was a Roman senator, who served as consul in 106 BC as the colleague of Quintus Servilius Caepio. Although noted by Cicero as being a "a most stupid man" (), he managed to defeat Quintus Lutatius Catulus in the consular elections of the previous year. Before this, Serranus had presumably held the office of praetor by 109 BC, a necessary requirement in the senatorial career track.
