Arrived in the Laconian capital, Themistocles demanded no public audience, avoided all occasions of opening the questions in dispute, and screened the policy of delay beneath the excuse that his colleagues were not yet arrived--that he was incompetent to treat without their counsel and concurrence--and that doubtless they would speedily appear in Sparta. When we consider the shortness of the distance between the states, the communications the Spartans would receive from the neighbouring Aeginetans, more jealous than themselves, and the astute and proverbial sagacity of the Spartan council--it is impossible to believe that, for so long a period as, with the greatest expedition, must have elapsed from the departure of Themistocles to the necessary progress in the fortifications, the ephors could have been ignorant of the preparations at Athens or the designs of Themistocles. I fear, therefore, that we must believe, with Theopompus [120], that Themistocles, the most expert briber of his time, heightened that esteem which Thucydides assures us the Spartans bore him, by private and pecuniary negotiations with the ephors. At length, however, such decided and unequivocal intelligence of the progress of the walls arrived at Sparta, that the ephors could no longer feel or affect incredulity. Themistocles met the remonstrances of the Spartans by an appearance of candour mingled with disdain. "Why," said he, "give credit to these idle rumours? Send to Athens some messengers of your own, in whom you can confide; let them inspect matters with their own eyes, and report to you accordingly." The ephors (not unreluctantly, if the assertion of Theopompus may be credited) yielded to so plausible a suggestion, and in the mean while the crafty Athenian despatched a secret messenger to Athens, urging the government to detain the Spartan ambassadors with as little semblance of design as possible, and by no means to allow their departure until the safe return of their own mission to Sparta. For it was by no means improbable that, without such hostages, even the ephors, however powerful and however influenced, might not be enabled, when the Spartans generally were made acquainted with the deceit practised upon them, to prevent the arrest of the Athenian delegates.
