grandson, Didius Julianus, when it was set up at auction by the praetorian guards. More eminent as a man of letters than either of these is their contemporary Gaius, whose _Institutes of Civil Law_, published at the beginning of the reign of Marcus Aurelius, have ever since remained one of the foremost manuals of Roman jurisprudence. But the literary poverty of this age in Latin writing is most strikingly indicated by merely naming its principal author. At any previous period the name of Gaius Suetonius Tranquillus would have been low down in the second rank: here it rises to the first; nor is there any other name which fairly equals his, either in importance or in interest. The son of an officer of the thirteenth legion, Suetonius practised in early life as an advocate, subsequently became one of Hadrian's private secretaries, and devoted his later years to literary research and compilation, somewhat in the manner, though without the encyclopedic scope, of Varro. In his youth he had been an intimate friend of the younger Pliny, who speaks in high terms of his learning and integrity. The greater part of his voluminous writings are lost; they included many works on grammar, rhetoric, and archaeology, and several on natural history and physical science. Fragments survive of his elaborate treatise _De Viris Illustribus,_ an exhaustive history of Latin literature up to his own day: excerpts made from it by St. Jerome in his _Chronicle_ are the source from which much of our information as to Latin authors is derived, and several complete lives have been prefixed to manuscripts of the works of the respective authors, and thus independently preserved. But his most interesting, and probably his most valuable work, the _Lives of the Twelve Caesars_, has made him one of the most widely known of the later classical writers. It was published under Hadrian in the year 120, and dedicated to his praetorian prefect, Septicius Clarus. Tacitus (perhaps because he was still alive) is never mentioned, and not certainly made use of. Both authors had access, in the main, to the same materials; but the confidential position of Suetonius as Hadrian's secretary no doubt increased his natural tendency to collect stories and preserve all sorts of trivial or scandalous gossip, rather than make any attempt to write serious history. It is just this, however, which gives unique interest and value to the _Lives of the Caesars_. We can spare political insight or consecutive arrangement in an author who is so lavish in the personal detail that makes much of the life of history; who tells us the colour of Caesar's eyes, who quotes from a dozen private letters of Augustus, who shows us Caligula shouting to the moon from his palace roof, and Nero lecturing on the construction of the organ. There perhaps never was a series of biographies so crammed with anecdote. Nor is the style without a certain sort of merit, from its entire and unaffected simplicity. After
