“The flying madness is described as making his body so light that he could perch in the tops of trees, and leap desperate leaps of a hundred feet or more without injury… Feathers then sprouted on Suibne’s body, and he lived like the wild things: feeding on sloes, hollyberries, watercress, brooklime, acorns; sleeping in yew-trees and rocky clefts of ivy-clad cliffs, and even in hawthorn and bramble bushes. The slightest noise would startle him into flight, and he was cursed with a perpetual distrust of all men.” — Robert Graves
