Last week we told the old stories. Today we ask who wrote them. The leprechaun probably isn't named after his "little body" at all, but after Roman priests whom Irish monks took for a race of wolf-men. His oldest story is a teaching tale about the law of distraint. In the nineteenth century he wore red, not green. The book that made him famous was lost by its editor and rewritten by his friends, and then translated by the Brothers Grimm. And when Walt Disney was offered Ireland's greatest folklore archive, he chose an American children's book instead.

Shows that the oldest manuscript form is lupracán, argues that the "little body" reading is linguistically very hard to sustain, and derives the word from the Luperci, whom Irish scholars, via Augustine, understood as a race of shapeshifters.
