He does not add the precise relation of these streets to one another.

If, however, the results of recent German inquiries and conjectures are correct, and if they show us his work and not--as is unfortunately very possible--the work of some later man, his design included streets running parallel or at right angles to one another and rectangular blocks of houses; the longer and presumably the more important streets ran parallel to the shore, while shorter streets ran at right angles to them down to the quays.

Here is a rectangular scheme of streets, though the outline of the whole town is necessarily not rectangular (fig.

Another town ascribed to Hippodamus is the colony which the Athenians and others planted in 443 B.C.at Thurii in southern Italy, of which Herodotus himself is said to have been one of the original colonists.
Its site has never been excavated, and indeed one might doubt whether excavation would show the street plan of 443 B.C.or that of a later and possibly even of a Roman age, when the town was recolonized on the Roman system.

But the historian Diodorus, writing in the first century B.C.and no doubt embodying much older matter, records a pertinent detail.
