»In which we remain in suspense
The New York Times has an article on bridges: bridges of the Incas.
In a recent research paper, Dr. [John A.] Ochsendorf wrote: “The Inca were the only ancient American civilization to develop suspension bridges. Similar bridges existed in other mountainous regions of the world, most notably in the Himalayas and in ancient China, where iron chain suspension bridges existed in the third century B.C.”
