Acilius Rufus is the name of a Roman senator, who was suffect consul in the nundinium of March to April 107; it unclear which consul ordinarius of the year Rufus replaced, Lucius Licinius Sura or Quintus Sosius Senecio.
[3] This inscription attests that this Acilius Rufus held the traditional republican magistracies of quaestor of Sicilia, plebeian tribune, praetor, and prefect of the frumenti dandi ex senatus consultum.
Although there appears to be no reason not to identify this person with the consul, Ronald Syme objects arguing that the first suffect consul of a year was a very prestigious post, and that having been quaestor of Sicilia and prefect of the frumenti dandi, Acilius Rufus lacked sufficient esteem for him to achieve that prestigious rank of suffect consuls.
[5] Despite his proven discernment for the evidence, Syme appears to depend too heavily on an argument from silence—especially as we know so little about many consuls of this time—to not allow for the vagaries of life.
In this case, Licinius Sura vanishes from the record after his consulate, so it is possible he died unexpectedly in March 107 and the consular Acilius Rufus, who is attested as replacing a single consul, may have been selected at the last moment to complete the nundinium.
