"None So Blind" is a fantasy short story by Harry Turtledove, first published in The Dragon Book, edited by Jack Dann and Gardner Dozois, Ace, 2009. It concerns an exploratory expedition by the Empire of Mussalmi to the tropical mountains south of its frontier. The maps of the Empire, since antiquity, had indicated "Here Be Dragons" over this territory. Part of the mandate of the expedition was to discover whether, in fact, dragons did exist.
