Larry Towell has frozen violence, the violence of the catapults and the Molotov cocktails and the Kalashnikovs, and of regular life for the little girls who pick their way among the rocks that litter the street when the protesters and soldiers move on.

It was an interest in human rights that led Towell to photograph "the culture of resistance." He recorded the effects of the Contra war in Nicaragua in the 1980s, the war in El Salvador, the mothers of "The Disappeared" in Guatemala, the rebellion in the Chiapas region of Mexico.

In the Israeli-Palestinian conflict he finds another twist on a theme that intrigues him: Landlessness, and what happens to a people when they lose their land. He first went to the region while the Intifada still raged, in January, 1993, then returned two days after the Oslo Accord was signed in Washington on September 13, drawn by the sense that history was happening.
