I am now arrived at the most difficult part of my undertaking, which is to compare Horace with Juvenal and Persius. It is observed by Rigaltius in his preface before Juvenal, written to Thuanus, that these three poets have all their particular partisans and favourers. Every commentator, as he has taken pains with any of them, thinks himself obliged to prefer his author to the other two; to find out their failings, and decry them, that he may make room for his own darling. Such is the partiality of mankind, to set up that interest which they have once espoused, though it be to the prejudice of truth, morality, and common justice, and especially in the productions of the brain. As authors generally think themselves the best poets, because they cannot go out of themselves to judge sincerely of their betters, so it is with critics, who, having first taken a liking to one of these poets, proceed to comment on him and to illustrate him; after which they fall in love with their own labours to that degree of blind fondness that at length they defend and exalt their author, not so much for his sake as for their own. It is a folly of the same nature with that of the Romans themselves in their games of the circus. The spectators were divided in their factions betwixt the Veneti and the Prasini; some were for the charioteer in blue, and some for him in green. The colours themselves were but a fancy; but when once a man had taken pains to set out those of his party, and had been at the trouble of procuring voices for them, the case was altered: he was concerned for his own labour, and that so earnestly that disputes and quarrels, animosities, commotions, and bloodshed often happened; and in the declension of the Grecian empire, the very sovereigns themselves engaged in it, even when the barbarians were at their doors, and stickled for the preference of colours when the safety of their people was in question. I am now myself on the brink of the same precipice; I have spent some time on the translation of Juvenal and Persius, and it behoves me to be wary, lest for that reason I should be partial to them, or take a prejudice against Horace. Yet on the other side I would not be like some of our judges, who would give the cause for a poor man right or wrong; for though that be an error on the better hand, yet it is still a partiality, and a rich man unheard cannot be concluded an oppressor. I remember a saying of King Charles II. on Sir Matthew Hale (who was doubtless an uncorrupt and upright man), that his servants were sure to be cast on any trial which was heard before him; not that he thought the judge was possibly to be bribed, but that his integrity might be too scrupulous, and that the causes of the Crown were always suspicious when the privileges of subjects were concerned.
