robbery,--even Catiline has found an able defender in Professor Beesly. It is claimed that Catiline was a man of great abilities and average good character, a well-calumniated leader of the Marian party which Caesar afterwards led to victory, and that his famous plot for burning Rome never existed save in the unscrupulous Ciceronian fancy. And those who think it easy to refute these conclusions of Professor Beesly had better set to work and try it. Such are a few of the surprising questions opened by recent historical research; and in the face of them the public is quite excusable if it declares itself at a loss what to believe. These, however, are cases in which criticism has at least made some show of ascertaining the truth and detecting the causes of the prevalent misconception. That men like Catiline and Tiberius should have had their characters blackened is quite easily explicable. President Johnson would have little better chance of obtaining justice at the hands of posterity, if the most widely read history of his administration should happen to be written by a radical member of the Rump Congress. But the cases which Mr. Delepierre invites us to contemplate are of a different character. They come neither under the head of myths nor under that of misrepresentations. Some of them are truly vexed questions which it may perhaps always be impossible satisfactorily to solve. Others may be dealt with more easily, but afford no clew to the origin of the popularly received error. Let us briefly examine a few of Mr. Delepierre's "difficulties." And first, because simplest, we will take the case of the Alexandrian Library.
