"But this proved to be an idle dream, for they were not destined to escape from either God or the Romans," he wrote. "The legionnaires tore up the paving stones above the drainage channels and exposed their hiding place.
"There too were found the bodies of more than two thousand, some slain by their own hands, some by another's; but most of them died by starvation," Josephus wrote."The victors proceeded to loot, he wrote, "for many precious objects were found in these passages."
The new tunnel, lit by fluorescent bulbs and smelling of damp earth, has been cleared for much of its length but has not yet been opened to the public. Earlier this month, a team from The Associated Press walked through the tunnel from the biblical Pool of Siloam, one of the city's original water sources, continuing for 600 yards (meters) under the Palestinian neighborhood named for the pool — Silwan — before climbing out onto a sunlit Roman-era street inside Jerusalem's Old City.
The tunnel is part of the expanding City of David excavation in Silwan, which sits above the oldest section of Jerusalem. The dig is named for the biblical monarch thought to have ruled from the site. It is funded by a group affiliated with the Jewish settlement movement and has drawn criticism from Palestinian residents who have charged that the work is disruptive and politically motivated.
Israel and the Palestinians have conflicting claims over Jerusalem that have scuttled peace efforts for decades. Both sides claim the Old City, which includes sites holy to Christians, Muslims and Jews.
The excavation of the tunnel began in 2007. Last month, a worker found a tiny golden bell that seemed to have been an ornament on the clothing of a rich man, or possibly a Temple priest, and which could still ring 2,000 years later.
When the tunnel opens to the public sometime in the coming months, underground passages totaling about a mile (1.6 kilometers) in length will be accessible beneath Jerusalem. The tunnels have become one of the city's biggest tourist draws and the number of visitors has risen in recent years to more than a million in 2010.
The tunnels remain, however, a sensitive political issue. While for Israelis they are proof of the extent of Jewish roots here, for many Palestinians, who reject Israel's sovereignty in the east Jerusalem, they are a threat to their own claims to the city and represent an exaggerated focus on Jewish history.
The 1996 opening of a new exit to a tunnel underneath the Old City's Muslim Quarter sparked rumors among Palestinians that Israel meant to damage the mosque compound, and dozens were killed in the ensuing riots. In recent years, however, criticism has been muted and work has largely gone ahead without incident.
