  • "I learn from Topsell's Gesner, whose authority appears to be Albertus, that the following is the way in which the hedgehog collects and carries home his apples. He says: "His meat is apples, worms, or grapes: when he findeth apples or grapes on the earth, he rolleth himself upon them, until he have filled all his prickles, and then carrieth them home to his den, never bearing above one in his mouth; and if it fortune that one of them fall off by the way, he likewise shaketh off all the residue, and walloweth upon them afresh, until they be all settled upon his back again." - 'Wild Apples', Henry David Thoreau.

  • The hedgehog has the appearance of a young pig, but is entirely covered with sharp spines or quills, which protect it from danger. When it is time for the harvest, the hedgehog goes into a vineyard, and climbing up a vine, shakes the grapes off onto the ground. It then rolls around on the fallen grapes to spear them with its quills, so it can carry the fruit home to feed its young. (Some say that the fruit the hedgehog carries away is the apple or fig.)
