That Heroine is a mere Intruder; and her Story afterwards in the Eleventh Book is no _Episode_. In short, it matters not whether we say those Incidents _flow_, or _arise from_ the Subject; or are _added_, and _connected to it_; or _inserted_, and _interwoven with_ it: If they are _natural_, and _proper Parts_ of the _Poem_, That is sufficient; all the rest is a Dispute about Words, and of no Importance, or Significancy. However it be, I think I cannot better represent the several sorts of Episodes which I have mentioned, than by an Instance nearly ally'd to my Subject; I mean that of a General making a Campaign. All the important Undertakings, and Performances of Himself, or the Gross of his Army, or Both, in pursuance of the Design proposed, are direct Parts of the main Action; and so far the Campaign, and the Poem agree even in Terms. If he sitting in his Tent either gives, or hears, the Recital of something past, the Knowledge of which is absolutely necessary to the Prosecution of his Enterprize; This indeed is not Action: But still it was said to be absolutely necessary in order to the Prosecution of his Enterprize. And so is that Narration of _Æneas_ in the Second, and Third Books, in order to the carrying on of the Action, and to shew the Reason of it. This in War would not be called an Episode; but it is so in Poetry. Should the same General detach a Part of his Army upon a particular Expedition; and the Commander of that Body behave himself with uncommon Gallantry, and attempt something very extraordinary, and to be distinguished in History; whether he succeeded in that Attempt or not: This would indeed be a Part of the Campaign; but perhaps not a necessary one; because the Campaign might have subsisted, and have been successful, or unsuccessful, with it, or without it. Such are the Episodes of _Nisus_ and _Euryalus_; of _Mezentius_; and of _Camilla_. The Case of the same General's being for some time diverted from Action by an Amour, or some such Incident, shall be considered in my Remarks upon the Fourth Book. But should he in Time of Inaction, tho' the Campaign still continued, entertain his Officers and Soldiers with warlike Sports and Recreations; or hear the Relation of some memorable Adventure, in the Place where he encamped (like the Adventure of _Hercules_, and _Cacus_) tho' no way concerning his own Affairs: These indeed would not be Parts of the Action of his Campaign; but still might be very properly recorded in History, and afford great Delight to the Reader; who would by no Means be offended either with the General, or the Historian; nor think the History of that Campaign to be less of a Piece, because the warlike Operations were for some Time suspended. For we must still remember, that tho' an Epic Poem be widely different from History in many Circumstances; yet it is more nearly ally'd to it, than any Dramatic Piece whatsoever. The learned Reader, I fear, will think I
