Perhaps the lightness of the matter may conduce to the vehemence of the agency; when the truth to be investigated is so near to inexistence, as to escape attention, its bulk is to be enlarged by rage and exclamation:  that to which all would be indifferent in its original state, may attract notice when the fate of a name is appended to it.  A commentator has, indeed, great temptations to supply by turbulence what he wants of dignity, to beat his little gold to a spacious surface, to work that to foam which no art or diligence can exalt to spirit.

The notes which I have borrowed or written are either illustrative, by which difficulties are explained; or judicial, by which faults and beauties are remarked; or emendatory, by which depravations are corrected.

The explanations transcribed from others, if I do not subjoin any other interpretation, I suppose commonly to be right, at least I intend by acquiescence to confess, that I have nothing better to propose.

After the labours of all the editors, I found many passages which appeared to me likely to obstruct the greater number of readers, and thought it my duty to facilitate their passage.  It is impossible for an expositor not to write too little for some, and too much for others.  He can only judge what is necessary by his own experience; and how long soever he may deliberate, will at last explain many lines which the learned will think impossible to be mistaken, and omit many for which the ignorant will want his help.  These are censures merely relative, and must be quietly endured.  I have endeavoured to be neither superfluously copious, nor scrupulously reserved, and hope that I have made my author’s meaning accessible to many, who before were frighted from perusing him, and contributed something to the publick, by diffusing innocent and rational pleasure.

The complete explanation of an author not systematick and consequential, but desultory and vagrant, abounding in casual allusions and light hints, is not to be expected from any single scholiast.  All personal reflections, when names are suppressed, must be in a few years irrecoverably obliterated; and customs, too minute to attract the notice of law, such as modes of dress, formalities of conversation, rules of visits, disposition of furniture, and practices of ceremony, which naturally find places in familiar dialogue, are so fugitive and unsubstantial, that they are not easily retained or recovered.  What can be known will be collected by chance, from the recesses of obscure and obsolete papers, perused commonly with some other view.  Of this knowledge every man has some, and none has much; but when an author has engaged the publick attention, those who can add any thing to his illustration, communicate their discoveries, and time produces what had eluded diligence.

To time I have been obliged to resign many passages, which, though I did not understand them, will, perhaps, hereafter be explained; having, I hope, illustrated some, which others have neglected or mistaken, sometimes by short remarks, or marginal directions, such as every editor has added at his will, and often by comments more laborious than the matter will seem to deserve; but that which is most difficult is not always most important, and to an editor nothing is a trifle by which his author is obscured.
