Cimon

And it is said that, though the building of the long walls, called legs, was completed afterwards, yet their first foundations, where the work was obstructed by swamps and marshes, were stayed up securely by Cimon, who dumped vast quantities of rubble and heavy stones into the swamps, meeting the expenses himself.

He was the first to beautify the city with the so-called liberal and elegant resorts which were so excessively popular a little later, by planting the market-place with plane trees, and by converting the Academy from a waterless and arid spot into a well watered grove, which he provided with clear running-tracks and shady walks.

Now there were certain Persians who would not abandon the Chersonese, but called in Thracians from the North to help them, despising Cimon, who had sailed out from Athens with only a few triremes all told.[*]( 466 B.C.) But he sallied out against them with his four ships and captured their thirteen, drove out the Persians, overwhelmed the Thracians, and turned the whole Chersonese over to his city for settlement.
