For example, Ronald Syme summarized his career in this sentence: "Veiento began as a dealer in petty patronage, and he ended as a merchant of honor.

[2] This has led more recent writers to evaluate him as "one of the most interesting of his Domitian's senatorial amici, frequently but erroneously classified as an informer during the so-called reign of terror.

"[3] His name suggests that Veiento was related to Aulus Didius Gallus, suffect consul of AD 39 and governor of Roman Britain.

[4] Jones speculates that it was while he was with Didius Gallus that he first met the future emperors, "for Domitian's father and brother commanded two of Claudius's legions in the British invasions.

S. J. de Laet proposed 41;[6] McDermott believed he was praetor in 54;[7] Jones in 1971 pointed out that "there is nothing to prevent its being dated to around 60, to some time towards the end of the Quinquennium Neronis",[6] although in a later publication admitted that 54 was "possible".

This was Nero's reason for himself undertaking the trial, and having convicted Veiento, he banished him from Italy, and ordered the burning of his books, which, while it was dangerous to procure them, were anxiously sought and much read.

"[10] McDermott points out the context of this passage — the preceding chapters narrate the recrudescence of charges under the Lex Julia maiestatis, or treason — suggests the motivation of this prosecution was not Veiento's "Codicils", instead an excuse to confiscate his property.

In a response to McDermott's paper, Brian Jones asserted "there is no evidence to suggest that Quintus Vibius Crispus could not have held the offices which the inscription mentions.

"[17] Further, Werner Eck offers a different restoration of the first line and argues that the inscription pertains to Marcus Pompeius Silvanus Staberius Flavianus.

A votive inscription of Trajanic date recording Veiento's satisfaction of a vow to the goddess Nemetona in Moguntiacum (Mainz) attests to the priesthoods he held.

[26] Veiento evidently survived the assassination of Domitian without loss of rank or property, for he next appears in history at a banquet hosted by the emperor Nerva during the first year of his reign (AD 97).

Pliny the Younger recounts how Veiento had been invited to the same dinner as Junius Mauricus, who had been exiled due to the efforts of a delator or informer.

Despite the fact Pliny was almost alone in pursuing the matter, through his eloquence he convinced the Senate to approve the prosecution, despite a final plea against legal actions from Veiento.

While the emperor Nerva failed to act on the motion to prosecute, Certus was passed over in consideration for a consulship, and in any event fell ill and died soon after this session of the Senate.

When offering a list of delatores active under Domitian, Tacitus names Mettius Carus, the blind Catullus Messalinus, and Baebius Massa, but not Veiento.
