"True to their name, the porters are moving stuff. They are nomads, refugees, asylum seekers or maybe even adventurers. They seem more industrious than driven, but mostly they are on the move, set in motion by forces beyond their control. They are universal, but you could locate them at any point on the maps, and they would become specific, displaced by this or that invasion, liberation, revolution, colonialism or economic crisis."
Roberta Smith, "Shadowy Nomads, Writ in Warp and Woof," New York Times, 31 December 2007, p. E1
