Artemis Fowl, (anti)hero of the eponymous novel series by Eoin Colfer, is a self-described criminal genius and prodigy. He is known to have broken numerous age records, perhaps most notably that of youngest person ever to steal the Fairy Thief painting (in book 4).
Is there any evidence to suggest that Colfer based him on any specific prodigy/ies, either real-life ones or from earlier fictional works? Or was he just a "juvenile criminal genius" with no specific pre-existing inspirations?
