This, according to Finkelstein, set the stage for motivations to compile and reconcile Hebrew history into a text at that time (157). Mazar questions this explanation, since, he argues, it is "no more than an educated guess" (167). The Siloam Tunnel was chiseled through 533 meters (1,750 feet) of solid rock in order to provide Jerusalem underground access to the waters of the Gihon Spring or Siloam Pool, which lay outside the city. The Siloam Inscription from the Siloam Tunnel is now in the Istanbul Archaeology Museum. It "commemorates the dramatic moment when the two original teams of tunnelers, digging with picks from opposite ends of the tunnel, met each other" (564). It is "[o]ne of the most important ancient Hebrew inscriptions ever discovered." Finkelstein and Mazar cite this tunnel as an example of Jerusalem's impressive state-level power at the time. Archaeologists like William G. Dever have pointed at archaeological evidence for the iconoclasm during the period of Hezekiah's reign. The central cult room of the temple at Arad (a royal Judean fortress) was deliberately and carefully dismantled, "with the altars and massebot" concealed "beneath a Str. 8 plaster floor". This stratum correlates with the late 8th century; Dever concludes that "the deliberate dismantling of the temple and its replacement by another structure in the days of Hezekiah is an archeological fact. I see no reason for skepticism here." Under Rehoboam, Lachish became the second-most important city of the kingdom of Judah. During the revolt of king Hezekiah against Assyria, it was captured by Sennacherib despite determined resistance (see Siege of Lachish). As the Lachish relief attests, Sennacherib began his siege of the city of Lachish in 701 BCE. The Lachish Relief graphically depicts the battle, and the defeat of the city, including Assyrian archers marching up a ramp and Judahites pierced through on mounted stakes. "The reliefs on these slabs" discovered in the Assyrian palace at Nineveh "originally formed a single, continuous work, measuring 8 feet ... tall by 80 feet ... long, which wrapped around the room" (559). Visitors "would have been impressed not only by the magnitude of the artwork itself but also by the magnificent strength of the Assyrian war machine."
