THE DECLINE AND FALL

armourer Marius, the most contemptible of all the candidates for the purple, was distinguished however by intrepid courage, matchless strength, and blunt honesty.[1] His mean and recent trade cast, indeed, an air of ridicule on his elevation; but his birth could not be more obscure than was Their obscure birththat of the greater part of his rivals, who were born of peasants, and enlisted in the army as private soldiers. In times of confusion every active genius finds the place assigned him by nature; in a general state of war military merit is the road to glory and to greatness. Of the nineteen tyrants Tetricus only was a senator; Piso alone was a noble. The blood of Numa, through twenty-eight successive generations, ran in the veins of Calphurnius Piso,[2] who, by female alliances, claimed a right of exhibiting in his house the images of Crassus and of the great Pompey.[3] His ancestors had been repeatedly dignified with all the honours which the commonwealth could bestow; and, of all the ancient families of Rome, the Calphurnian alone had survived the tyranny of the Cæsars. The personal qualities of Piso added new lustre to his race. The usurper Valens, by whose order he was killed, confessed, with deep remorse, that even an enemy ought to have respected the sanctity of Piso; and, although he died in arms against Gallienus, the senate, with the emperor's generous permission, decreed the triumphal ornaments to the memory of so virtuous a rebel.[4]

  2. Vos O Pompilius sanguis! is Horace's address to the Pisos. See Art. Poet. v. 292, with Dacier's and Sanadon's notes.
  3. Tacit. Annal. xv. 48, Hist. i. 15. In the former of these passages we may venture to change paterna into materna. In every generation from Augustus to Alexander Severus, one or more Pisos appear as consuls. A Piso was deemed worthy of the throne by Augustus (Tacit. Annal. i. 13). A second headed a formidable conspiracy against Nero; and a third was adopted, and declared Cæsar by Galba.
  4. Hist. August. p. 195 [xxiv. 20]. The senate, in a moment of enthusiasm, seems to have presumed on the approbation of Gallienus.
