"At the beginning of the Isthmus is the place where the brigand Sinis used to take hold of pine trees and draw them down. All those whom he overcame in fight he used to tie to the trees, and then allow them to swing up again. Thereupon each of the pines used to drag to itself the bound man, and as the bond gave way in neither direction but was stretched equally in both, he was torn in two. This was the way in which Sinis himself was slain by Theseus."
