Yet side by side with a passage like this, there are descriptions of abnormal depravity so coarsely realistic that it has often been assumed, and not unnaturally, that the writer rioted in mere filth. It should be remembered, however, that there was a tradition of immorality about the ancient romance,(746) and Petronius, had he cared to do so, might have made the same apology as Martial, that he provided what his readers demanded.(747) That Petronius was deeply tainted is only too probable from his associations, although Tacitus implies that he was rather a fastidious voluptuary than a gross debauchee. Yet a sensualist of the intellectual range of Petronius may have occasionally visions of a better world than that to which he has sunk. Is it not possible that the gay elegant trifler may sometimes have scorned himself as he scorned his time? Is it not possible that, along with other illusions, he had parted with the illusions of vice, and that in the “noctes Neronis” he had seen the adder among the roses? He has written one of the keenest satires ever penned on the vulgarity of mere wealth, its absurd affectations, its vanity, its grossness. May he not also have wished, without moralising in a fashion which so cultivated a trifler would have scorned, to reveal the abyss towards which a society lost to all the finer passions of the spirit was hurrying? In the half comic, half ghastly scene in which Trimalchio, in a fit of maudlin sentiment, has himself laid out for dead, while the horns blare out his funeral lament, we seem to hear the knell of a society which was the slave of gold and gross pleasure, and seemed to be rotting before its death. But it need hardly be said that the prevailing note of the _Satiricon_ is anything but melancholy. The author is intensely amused with his subject, and the piece is full of the most riotous fun and humour. It belongs formally to the medley of prose and verse which Varro introduced into Roman literature on the model of Menippus of Gadara.(748) It contains disquisitions on literary tendencies of the day in poetry and oratory, anecdotes and desultory talk. But Petronius has given a new character to the old “Satura,” more in the manner of the Greek romance. There probably was no regular plot in the complete work, no central motive, such as the wrath of Priapus,(749) to bind it together. Yet there is a certain bond of union in the narrative of lively, and often questionable, adventures through which Petronius carries his very disreputable characters. In this life and movement, this human interest, the _Satiricon_ is the distant ancestor of _Gil Blas_, _Roderick Random_, and _Tom Jones_.
