That several of the passages in which Nestor speaks are very late interpolations, meant to glorify Pisistratus, himself of Nestor's line, is a critical opinion to which we have more than once alluded. The first example is in _Iliad,_ II. 530-568. This passage "is meant at once to present Nestor as the leading counsellor of the Greek army, and to introduce the coming _Catalogue_." [Footnote: Leaf, _Iliad,_ vol. i. p. 70.] Now the _Catalogue_ "originally formed an introduction to the whole Cycle." [Footnote: Ibid., vol. i. p. 87.] But, to repeat an earlier observation, surely the whole Cycle was much later than the period of Pisistratus and his sons; that is, the compilation of the Homeric and Cyclic poems into one body of verse, named "The Cycle," is believed to have been much later. It is objected that Nestor's advice in this passage, "Separate thy warriors by tribes and clans" ([Greek: phyla, phraetras]), "is out of place in the last year of the war"; but this suggestion for military reorganisation may be admitted as a mere piece of poetical perspective, like Helen's description of the Achaean chiefs in Book III, or Nestor may wish to return to an obsolete system of clan regiments. The Athenians had "tribes" and "clans," political institutions, and Nestor's advice is noted as a touch of late Attic influence; but about the nature and origin of these social divisions we know so little that it is vain to argue about them. The advice of Nestor is an appeal to the clan spirit--a very serviceable military spirit, as the Highlanders have often proved--but we have no information as to whether it existed in Achaean times. Nestor speaks as the aged Lochiel spoke to Claverhouse before Killiecrankie. Did the Athenian army of the sixth century fight in clan regiments? The device seems to belong to an earlier civilisation, whether it survived in sixth century Athens or not. It is, of course, notorious that tribes and clans are most flourishing among the most backward people, though they were welded into the constitution of Athens. The passage, therefore, cannot with any certainty be dismissed as very late, for the words for "tribe" and "clan" could not be novel Athenian inventions, the institutions designated being of prehistoric origin.
