Quirinius is mentioned once in the New Testament in the Gospel of Luke 2:1-3:

And it came to pass in those days that a decree went out from Caesar Augustus that all the world should be registered. This census first took place while Quirinius was governing Syria.  So all went to be registered, everyone to his own city.

Suetonius mentions Quirinius in his discussion of Emperor Tiberius.

Tiberius 49:

In the course of a very short time, he [Tiberius] turned his mind to sheer robbery. It is certain that Cneius Lentulus, the augur, a man of vast estate, was so terrified and worried by his threats and importunities, that he was obliged to make him his heir; and that Lepida, a lady of a very noble family, was condemned by him, in order to gratify Quirinus, a man of consular rank, extremely rich, and childless, who had divorced her twenty years before, and now charged her with an old design to poison him.

In my reading of Tacitus I missed references to Quirinius.  Here they are:

Annals 2.30

As an ancient statute of the Senate forbade such inquiry in a case affecting a master’s life, Tiberius, with his cleverness in devising new law, ordered Libo’s slaves to be sold singly to the State-agent, so that, forsooth, without an infringement of the Senate’s decree, Libo might be tried on their evidence. As a consequence, the defendant asked an adjournment till next day, and having gone home he charged his kinsman, Publius Quirinus, with his last prayer to the emperor.

Annals 3.22-23

At Rome meanwhile Lepida, who beside the glory of being one of the Æmilii was the great-granddaughter of Lucius Sulla and Cneius Pompeius, was accused of pretending to be a mother by Publius Quirinus, a rich and childless man. Then, too, there were charges of adulteries, of poisonings, and of inquiries made through astrologers concerning the imperial house. The accused was defended by her brother Manius Lepidus. Quirinus by his relentless enmity even after his divorce, had procured for her some sympathy, infamous and guilty as she was. One could not easily perceive the emperor’s feelings at her trial; so effectually did he interchange and blend the outward signs of resentment and compassion. He first begged the Senate not to deal with the charges of treason, and subsequently induced Marcus Servilius, an ex-consul, to divulge what he had seemingly wished to suppress. He also handed over to the consuls Lepida’s slaves, who were in military custody, but would not allow them to be examined by torture on matters referring to his own family. Drusus too, the consul-elect, he released from the necessity of having to speak first to the question. Some thought this a gracious act, done to save the rest of the Senators from a compulsory assent, while others ascribed it to malignity, on the ground that he would have yielded only where there was a necessity of condemning.

On the days of the games which interrupted the trial, Lepida went into the theatre with some ladies of rank, and as she appealed with piteous wailings to her ancestors and to that very Pompey, the public buildings and statues of whom stood there before their eyes, she roused such sympathy that people burst into tears and shouted, without ceasing, savage curses on Quirinus, “to whose childless old-age and miserably obscure family, one once destined to be the wife of Lucius Cæsar and the daughter-in-law of the Divine Augustus was being sacrificed.” Then, by the torture of the slaves, her infamies were brought to light, and a motion of Rubellius Blandus was carried which outlawed her. Drusus supported him, though others had proposed a milder sentence. Subsequently, Scaurus, who had had a daughter by her, obtained as a concession that her property should not be confiscated. Then at last Tiberius declared that he had himself too ascertained from the slaves of Publius Quirinus that Lepida had attempted their master’s life by poison.

Annals 3.48

About the same time he requested the Senate to let the death of Sulpicius Quirinus be celebrated with a public funeral. With the old patrician family of the Sulpicii this Quirinus, who was born in the town of Lanuvium, was quite unconnected. An indefatigable soldier, he had by his zealous services won the consulship under the Divine Augustus, and subsequently the honours of a triumph for having stormed some fortresses of the Homonadenses in Cilicia. He was also appointed adviser to Caius Cæsar in the government of Armenia, and had likewise paid court to Tiberius, who was then at Rhodes. The emperor now made all this known to the Senate, and extolled the good offices of Quirinus to himself, while he censured Marcus Lollius, whom he charged with encouraging Caius Cæsar in his perverse and quarrelsome behaviour. But people generally had no pleasure in the memory of Quirinus, because of the perils he had brought, as I have related, on Lepida, and the meanness and dangerous power of his last years.

Next week I will post Josephus’ references to Quirinius as well as Strabo’s.
