The five periods, from Peisistratus down to the death of Alexander and of his generation, present the acts of an historical drama capable of being recounted in perspicuous succession, and connected by a sensible thread of unity. I shall interweave in their proper places the important but outlying adventures of the Sicilian and Italian Greeks,—introducing such occasional notices of Grecian political constitutions, philosophy, poetry, and oratory, as are requisite to exhibit the many-sided activity of this people during their short but brilliant career. After the generation of Alexander, the political action of Greece becomes cramped and degraded,—no longer interesting to the reader, or operative on the destinies of the future world. We may, indeed, name one or two incidents, especially the revolutions of Agis and Kleomenês at Sparta, which are both instructive and affecting; but as a whole, the period, between 300 B. C. and the absorption of Greece by the Romans, is of no interest in itself, and is only so far of value as it helps us to understand the preceding centuries. The dignity and value of the Greeks from that time forward belong to them only as individual philosophers, preceptors, astronomers, and mathematicians, literary men and critics, medical practitioners, etc. In all these respective capacities, especially in the great schools of philosophical speculation they still constitute the light of the Roman world; though, as communities, they have lost their own orbit, and have become satellites of more powerful neighbors. I propose to bring down the history of the Grecian communities to the year 300 B. C., or the close of the generation which takes its name from Alexander the Great, and I hope to accomplish this in eight volumes altogether. For the next two or three volumes I have already large preparations made, and I shall publish my third (perhaps my fourth) in the course of the ensuing winter.
