Fausto Zevi[1] postulated that he was also suffect consul in 97, based on a plausible restoration of part of the Fasti Ostienses, which reads "..]us".
The second (VI.64) is published in 89/90, wherein Martial defends his trifles against criticism by appealing to the highest authorities, who include, besides Sura, Silius Italicus, consul in 68, Marcus Aquilius Regulus, and the emperor himself.
Edmund Groag surmised that it was Sura who suggested Trajan's name as an heir to the emperor Nerva after the latter was confronted by a mutiny by the Praetorian Guard.
[9] However, this view has been challenged: when discussing the details of Nerva's choice of Trajan as an heir in October 97, John D. Grainger simply omits all mention of Groag's theory.
[13] He also participated in Trajan's second campaign against the Dacians; while his role in that war is undetermined, it was important enough for Sura to be awarded triumphal ornaments and a third consulate in 107 with Quintus Sosius Senecio as his colleague.
