Pausanias Description of Greece 1.44.6

[6] As one proceeds from Megara to Corinth, there are tombs [ taphoi], including that of the aulos-player Telephanes of Samos. 150

The tomb [ taphos] is said to have been made [ poieîn] by Kleopatra, daughter of Philip son of Amyntas. There is also the tomb [ mnēma] of Kar, son of Phoroneus, which was originally a piled-up-mound [ khōma] of earth, but afterwards, in accordance with what the god [ theos] said-in-an-oracular-pronouncement [ khrēsai], it was adorned [ kosmeîn] with a kind of stone known as konkhītēs [‘in-which-seashells [ konkhoi]-are-embedded’]. The people of Megara are the only Greeks [ Hellēnes] to possess this kind of konkhītēs stone, and in the city also they have made [ poieîn] many things out of it. It is very white, and softer than other stone; embedded in it through and through are seashells [ konkhoi]. Such, then, is the stone itself. [As for rock formations that are also white…] There is a road called Skīrōnis—that is what it is called even to this day—and it is named after Skīrōn [= ‘he of the White Rock’]. This Skīrōn, when he was the military leader of the people of Megara, was the first, they say, to make [ poieîn] it [= Skīrōnis] a road usable enough for men who outfit themselves for travel. But then ‘King’ [ basileus] Hadrian broadened it, and made it more usable—so much so that even chariots [ harmata] could pass each other going in opposite directions.
