Also, today on the "Behind the Book" feature for AMONG THE RUINS, I'd like to introduce you to the Siosepol bridge in Esfahan. Esa Khattak meets the young dissidents Ali and Taraneh near this bridge that spans Iran's Zayanderud River. "They disembarked at the south end of Siosepol Bridge, a Safavid construction mounted on a series of pontoons. Its thirty-three arches burned like the embers of a giant's torch, an auroral glow reflected in the river. If a sorcerer had flung open his hand, so might the arches of Siosepol have sprung up."
