When asserting generally the historic aims and authority of the poet, I do not presume to pronounce confidently upon the difficult question of the period at which he lived. I prefer to dwell upon the proposition that he is an original witness to manners, characters, and ideas such as those of his poems. It is not necessary, to make good this proposition, that we should determine a given number of years as the maximum that could have passed between the Trojan war and the composition of the Iliad or Odyssey. But the internal evidence seems to me very strongly to support the belief, that he lived before the Dorian conquest of the Peloponnesus. That he was not an eye-witness of the war, we absolutely know from the Invocation before the Catalogue[29]. It also appears[30] that he must have seen the grandchildren of Æneas reigning over the land of Priam. It is no extravagant supposition that forty or fifty years after the siege, perhaps even less, might have brought this to pass. The single idea or form of expression in the poems, which at first sight tends to suggest a very long interval, is that quoted by Velleius Paterculus[31], the οἷοι νῦν βροτοί εἰσι[32]. But the question arises, whether this is an historical land-mark, or a poetical embellishment? In the former sense, as implying a great physical degeneracy of mankind, it would require us to suppose nothing less than a lapse of centuries between the Troica and the epoch of the poet. This hypothesis, though Heyne speaks of the eighth or ninth generation[33], general opinion has rejected. If it be dismissed, and if we adopt the view of this formula as an ornament, it loses all definite chronological significance. Thus it is lost in the phrase, common in our own time with respect to the intellectual characters of men now no more, but yet not removed from us, perhaps, by more than from a quarter to half a century--‘there were giants in those days.’ Nay, the observation of Paterculus, especially as he was an enthusiastic admirer, itself exemplifies the little care with which these questions have been treated. For the Iliad itself supplies a complete answer in the speech of Nestor, who draws the very same contrast between the heroes of the Troica and those of his own earlier days: κείνοισι δ’ ἂν οὔτις τῶν οἱ νῦν βροτοί εἰσιν ἐπιχθονίων μαχέοιτο[34].
