Aratus

When Aratus had heard this, he sent with Xenocles two servants of his own, Seuthas and Technon, to make an examination of the wall; for he was resolved, if he could, to hazard the whole enterprise on one secret and swift attempt, rather than in a long war and in open contests to match his private resources against those of a tyrant.

So when Xenocles and his party came back with measurements of the wall which they had taken, and with a report that the place was by nature not impassable nor even difficult (although they declared that it was hard to get to it undetected owing to a certain gardener’s dogs, which were little beasts, but extraordinarily fierce and savage), Aratus at once undertook the business.

Now the laying in of arms was nothing unusual, since almost everybody at that time indulged in robberies and predatory forays; and as for scaling-ladders, Euphranor the engineer made them openly, since his trade screened him from suspicion; and he too was one of the exiles.
