to have undergone such a change; and Peloponnesus lost no considerable part of its original population till long after the whole had become Hellenic." (P. 54.) Herodotus had said that certain Pelasgians living in his time spoke a language different from the Greeks. Dr Thirlwall puts the passage of Herodotus upon the rack to extract from it a confession that the difference was not greater than between one dialect of Greek from another. Yet, as the narrative proceeds--if narrative it can be called--we have the Pelasgians and the Greeks represented as essentially distinct people; and we hear of the difficulty of determining "the precise point of civilisation to which the Pelasgians had advanced, before the Greeks overtook and outstripped them." The whole treatise, notwithstanding the air of decision now and then assumed, is but an amplification of the doubt implied in the very first sentence of it. The legends which fill up the dark space with _eponymous_ heroes, as they have been called--heroes who take the name of a tribe in order to bestow it back upon the tribe; for it was the Greek mode of thinking at these early periods to presume that every tribe, or _gens_, had a common progenitor from whom it took its title and origin,--these legends are at one time treated with the due suspicion which should attend upon them; yet, at another, if a fortunate congruity, some lucky "dovetailing," can be observed amongst them, they are raised into the rank of historical evidence. The mode of interpretation which we have described as characterising the first and undisciplined age of critical inquiry, is not laid aside. Such personages as Danaus and Aeolus are still referred to on emergency; and Dr Thirlwall still speaks of the Centaurs as "a fabulous race, which, however, may be supposed to represent the earlier and ruder inhabitants of the land." If we must call in the Centaurs to our assistance, we may safely conclude with Mr Grote that the ancient Pelasgians are "not knowable."
