The scene is now changed, and not for the better. Still, if any one has no right to grumble, it is the archæologist, because the building of these suburban quarters has placed more knowledge at his disposal than could have been gathered before in the lapse of a century. I quote only one instance. Famous in the annals of Roman excavations are those made between 1695 and 1741 in the vineyard of the Naro family, between the Salaria and the Pinciana, back of the Casino di Villa Borghese. It took forty-six years to dig out the contents of that small property, which included twenty-six graves of prætorians and one hundred and forty-one of civilians. In 1887, in cutting open the Corso d' Italia, which connects the Porta Pinciana with the Salaria, eight hundred and fifty-five tombs were discovered in nine months. The cemetery extends from the Villa Borghese to the prætorian camp, from the walls of Servius Tullius to the first milestone. The gardens of Sallust were surrounded by it on two sides; a striking contrast between the silent city of death on the one hand, and the merriest and noisiest meeting-place of the living on the other. Although the cemetery was mostly occupied by military men, the high-roads which cross it were lined with mausolea belonging to historical families. Such is the tomb of the Licinii Calpurnii, discovered in 1884, in the foundations of the house No. 29, Via di Porta Salaria, the richest and most important of those found in Rome in my lifetime.[132] Its history is connected with one of the worst crimes of Messalina. There lived in Rome in her time a nobleman, Marcus Licinius Crassus Frugi, ex-prætor, ex-consul (A. D. 27) ex-governor of Mauritania, the husband of Scribonia, by whom he had three sons. There was never a more unlucky family than this. The origin of their misfortunes is curious enough. Licinius Crassus, whom Seneca calls "stupid enough to be made emperor," committed, among other fatuities, that of naming his eldest son Pompeius Magnus, after his great-grandfather on the maternal side: a useless display of pride, as the boy had titles enough of his own to place him at the head of the Roman aristocracy. Caligula, jealous of the high-sounding name, was the first to threaten his life; but spared it at the expense of the name. Claudius restored the title to him, as a wedding-present, on the day of his marriage with Antonia, daughter of the emperor himself by Ælia Pætina. His splendid career, his nobility and grace of manners, and his alliance with the imperial family, excited the hatred of Messalina, a foe far more dangerous than Caligula. She extorted from her weak husband the sentence of death against Pompeius and his father and mother. The execution took place in the spring of 47. The second son, Licinius Crassus, was murdered by Nero in 67.
