On the whole the narrative seems to fall best into the first half of the seventh century. That is the time that best suits the naval situation during the war, and the effect that it is said to have had upon costume, ornament, and pottery. As the archaeological evidence for all these points is based largely on the evidence of the pottery, it will be best to take the pottery first. [Sidenote: (i) pottery,] In the temple of Damia and Auxesia on Aegina it became the practice (νόμος) after the war “to introduce into the temple neither anything else Attic nor pottery, but to drink there henceforth only out of native jars[857].” Herodotus mentions this embargo on Attic pottery only as applied to the one temple on Aegina[858]. But he states that it was observed by Argives as well as by Aeginetans, which points to the possibility that the practice prevailed in Argos as well as Aegina. Macan goes as far as to suggest that it is an “understatement and pseudo-explanation of a measure or custom for the protection of native ware from Attic competition[859].” The other measures recorded in this connexion, the changes in Attic dress and in Peloponnesian brooches, support Macan’s suggestion. But in the matter of dating he follows earlier writers who, using very inadequate material, came to conclusions which can now be shown to be improbable. They date this embargo in the middle of the sixth century. But in Aegina at any rate Attic pottery continued to be imported throughout the second half of the sixth century, while in Argos, where the evidence is less decisive and abundant, there is no sign of a cessation of Attic imports about 550 B.C. On the other hand both in Argos and Aegina there does appear to be an abrupt cessation of Attic imports early in the seventh century. As, further, the general history of Greek pottery shows that an Argive-Aeginetan embargo on Attic pottery would have had a strong commercial motive early in the seventh century and none in the middle of the sixth, there is a strong presumption that the date of the embargo was not the middle of the sixth century but somewhere about the beginning of the seventh. To examine the archaeological evidence here in detail would take us too far from our main enquiry. It will be found presented in full in an appendix[860]. [Sidenote: (ii) sea-power and ships,]
