Of the Ionic order, few remains are extant in Greece or her colonies--few, we mean, as compared with the amazing structures just considered. The Temple of Juno, in the Isle of Samos, raised about the first Olympiad by Ræchus and Theodorus, already noticed as the founders of the Samian School of Sculpture, supplies the earliest specimen. This, in the age of Herodotus, was the grandest building in Greece. How rapidly the order must have improved! Many archaisms, not to say barbarous inventions, occur. Next in age has been placed the singular but not ungraceful monument at Agrigentum, called the Tomb of Theron. Here we discover, indeed, Ionic columns, but everything else is Doric--proofs, first, of the antiquity of the monument; and secondly, of the truth of our opinion, more than once hinted in these pages, that the Dorian colonies in Sicily were original settlements from the East, little or no intermediate connexion having taken place between them and the Dorians of the Peloponnesus, who affected to be considered as the mother country. If pursued to the full extent of its consequences, this position would go far to explain several doubts, in regard to the early power and arts of the Sicilian and Lucanian cities. The earliest example of the true Ionic, is the Temple of Bacchus at Teos, erected, most probably, soon after the Persian invasion, or not later than fifty years after, or about 440 B. C. At Athens, however, in the temples of Minerva, Polias, and Erectheus, is to be found the most perfect remain of this order, but of what precise date is uncertain,--probably about the era of the Peloponnesian war. Near Miletus, the Temple of Apollo, erected by the architects Peonius and Daphnis, brings us down to that of Minerva at Priene, by Pitheas, in the age of Alexander; after which no specimens are to be found more ancient than the Roman conquest, with the exception of some in different parts of Asia Minor, whose dates cannot be ascertained.
