to Athens, from which it follows that Hippias was still tyrant in Athens. Thucydides tells us that when Hippias, after the murder of Hipparchus, was looking about for alliances he married his daughter to Aeantides, the son of Hippoclus, tyrant of Lampsacus, because he saw that Hippoclus was in great repute with Darius. This influence Hippoclus must have gained in the Scythian expedition; he led the ships of his city to the Danube and voted for remaining there. Hence this expedition must be put some time before 510 B.C. If we allow two years for the battles of Megabyzus in Thrace, and the march of Bubares to Macedonia after the Scythian war, and place, as is natural, the expedition to the coasts of Hellas, which falls in the year 512 B.C., after these acquisitions, we might keep to the year 515 for the Scythian expeditions. But as the Indian conquests precede the Scythian war, the year 513 B.C. seems still better. The expedition to Barca is, in Herodotus, contemporaneous with the conflicts of Megabyzus against those "who were not of Median opinions" (4, 145). This contemporaneous date is supported by the fact that Greek ships only, and not Phenician, are ordered to the Danube, and to support the communications of Megabyzus with Asia,--a circumstance which is best explained by the absence of the Phenicians in the African expedition. Moreover, Justin (19, 1) speaks of an embassy of Darius to Carthage at the time when this city was engaged in a conflict with Doreus of Sicily (Herod. 5, 45-48; 7, 165; Diod. 4, 23). Such an embassy, which could only be sent to demand a recognition of supremacy or union in war against the Greeks, was first suggested when the Persians reached as far as the Euhesperides and Persia became a neighbour of Carthage, _i.e._ after the expedition to Barca. The colony of Dorieus on the Eryx was planted between 510 and 508; he had previously taken part in the battle on the Traeis in 311 or 510 B.C. The embassy of Darius to Carthage would therefore be subsequent to the campaign to Barca and the expedition of Democedes, and the years 513 and 512 seem most suitable for the first. From the inscriptions of Darius it is clear that the inscription of Persepolis, when compared with the inscription of Behistun, enumerates more subject lands. The former speaks of the Ionians of the continent and the Ionians of the sea (_daraya_), while the inscription of Behistun merely mentions the Ionians. By the Ionians of the sea we are to understand the newly-subjugated Greeks of Samos, the Greek cities on the Bosphorus and Propontis. Moreover, the inscription of Persepolis, as already mentioned, speaks of Idhus (p. 260), while the inscription of Behistun speaks of Gandaras only. It follows from this that the first undertakings of Darius after crushing the rebellion were the wars in the east, the conquests of Samos and the Greek cities on the straits. This is established by the statement of Herodotus that the Indians were
