The idea prevails extensively, at least by sufferance, that these three great names are in Homer mere synonyms, and have no reference to any actual and historical differences, either existing when Homer wrote, or known by him to have existed at a previous period. This question it is proposed now to examine. I commence by making a broad admission. It is this. Upon the face of the poems, and on almost all ordinary occasions, Homer seems at first sight to use, and he very frequently does use, as equivalent and interchangeable, those three principal designations which he applies to the Greeks in common. _Homer’s use of them distinctive._ It is a very important question, however, whether Homer knew of and observed any distinctions between these names. For if he did, then these mere commonplace words, as they are taken to be, may involve in them the germ of much early history. In this investigation, we have the advantage of dealing in great part, not with mere traditional assertion, but with facts. The use of particular names, at particular epochs, for particular tribes, affords (if the text can be trusted for genuineness) a class of evidence analogous to that supplied by coins and inscriptions for history, or that afforded by geological phænomena with respect to the formation of the globe. The poems of Homer, particularly the Iliad, abound in passages relating to prior occurrences. These passages are not in general of a high order of poetical beauty, as compared with the rest of the poem; they often cause the action to hang rather heavily; many of them make up the speeches of old men, whose natural leaning to loquacity it appears that the Poet has, with his usual skill, made to minister to the accomplishment of his own marked historic aims. But they are repositories stored, we may almost say packed, with the most curious and suggestive information. Some of them may be without date: but the time is generally fixed within limits sufficiently close, either by genealogies, or by the period in the lives of the narrators, to which the tales belong. The war of the Elians and Pylians in the Eleventh Book took place in the boyhood of Nestor: probably from fifty to sixty years before the war of Troy. The birth of Eurystheus, related in the Nineteenth Book, was probably earlier still by ten or twenty years. The other legends fall into the interval between these events and the _Troica_. Now if we can trace a difference in the application by Homer of his appellatives, either as to the times or the places, he may hereby conclusively, though unconsciously, tell us a good deal about his view of the succession, and the local distribution, of ruling races in Greece. Such a rule of difference is easy to be traced.
