It is impossible to give an adequate account of the evolution of criticism without a very careful survey of the chief contributors to criticism in each generation, and such a survey Mr. Worsfold has not attempted. To Latin criticism he never even refers. And yet it has had great influence on critical literature. The Romans, it is true, contributed scarcely anything new to criticism, except that which pertains to oratory. We know enough of Varro, with whom Roman criticism may be said to begin, to feel confident that he could have had no pretension to the finer qualities of the critic. Of the five treatises composed by him, only one, the περι χαρακτηρων, appears to have been purely critical, and it almost certainly drew largely on Greek sources. Horace derived the material of the _Ars Poetica_ from a Greek writer, Neoptolemus of Parium. Much of Quinctilian’s criticism is demonstrably a compilation from Greek writers. The best critic of poetry among the Romans is undoubtedly to be found in Petronius, occasional and scanty though his remarks are. But of prose literature Rome produced two really great critics--the one was Cicero, the other was Tacitus. The _Brutus_ and the _Dialogus de Oratoribus_ are masterpieces, equal to anything which has come down to us from the Greeks. One of the most important critical principles ever enunciated we owe to Cicero. He was the first to demonstrate that the test of excellence in oratory lay, in its appealing equally to the multitude and to the most fastidious of connoisseurs. The most consummate rhetorician which the world has ever seen, he was at the same time a consummate critic of his art. This department of criticism has, indeed, for nearly two thousand years, been practically his monopoly; it may be questioned whether anything can be added, so far as the technique of rhetoric is concerned, to what may be traced to his writings. The interest of the _Dialogus de Oratoribus_ is largely historical, but never have the causes which inspire and nourish, or depress and starve, eloquence been more eloquently and brilliantly explained. Nor must it be forgotten that it was through the medium of the Latin critics that Greek criticism became influential on modern literature.
