You find yourself on a bridge that is clearly antique, yet still serviceable. From here you peer down into the Tiber River, which has a tawny color near Rome. In the image above, the Pons Cestius extends to the island from the right, running roughly southwest-northeast. Looking across the bridge you see Tiber Island (Insula Tiberina), which resembles a Roman ship as you scan the whole of the island.
You may wish to pause to read some comments about the Tiber River (Tiberis Fluvius) made by ancient authors.
