The silver age produced no men who "attained unto these first three." But there are not wanting other bright names to associate with Tacitus, though most of them lived a little earlier than he. There was Seneca, the Philosopher, whose style, with its perpetual antitheses, is the very worst of the age, but his sentiments, perhaps more or less under the influence of Christianity, approach nearer to the Christian code of morals than those of any other Latin author. There were Martial and Juvenal, whose satires made vice tremble in its high places, and helped to confer on the Romans the honor of originating one species of literary composition, unknown to the Greeks. There were Suetonius and Plutarch; the one natural, simple, and pure in his style, far beyond his age, but without much depth or vigor of thought; the other involved and affected in his manner, but in his matter of surpassing richness and incalculable worth. There was the elder Pliny, a prodigy of learning and industry, whose researches in Natural History cost him his life, in that fatal eruption of Vesuvius which buried Herculaneum and Pompeii. There was also the judicious Quintilian, at once neat and nervous in his language, delicate and correct in his criticisms, a man of genius and a scholar, a teacher and an exemplar of eloquence. Finally, there were the younger Pliny and Tacitus, rival candidates for literary and professional distinction, yet cherishing for each other the most devoted and inviolable attachment, each viewing the other as the ornament of their country, each urging the other to write the history of their age, and each relying chiefly on the genius of the other for his own immortality (Plin. Epis. vii. 33). Their names were together identified by their contemporaries with the literature of the age of Trajan: "I never was touched with a more sensible pleasure," says Pliny, in one of his beautiful Letters [Eleven of these are addressed to Tacitus, and two or three are written expressly for the purpose of furnishing materials for his history.] (which rival Cicero's in epistolary ease and elegance), "than by an account which I lately received from Cornelius Tacitus. He informed me, that at the last Circensian Games, he sat next a stranger, who, after much discourse on various topics of learning, asked him whether he was an Italian or a Provincial. Tacitus replied, 'Your acquaintance with literature must have informed you who I am.' 'Aye,' said the man, 'is it then Tacitus or Pliny I am talking with?' I cannot express how highly I am pleased to find, that our names are not so much the proper appellations of individuals, as a designation of learning itself" (Plin. Epis. ix. 23). Critics are not agreed to which of these two literary friends belongs the delicate encomium of Quintilian, when, after enumerating the principal writers of the day, he adds, "There is another ornament of the age, who will deserve the admiration of posterity.
