Dragons are quintessential fairy-tale monsters. Inordinately large, with incendiary or venomous breath and an insatiable appetite for fair maidens, they function as formidable foes whose defeat proves the hero’s valor. Unlike for today’s readers, however, for early modern Italians dragons did not dwell exclusively on the pages of literary fairy tales. They also appeared on the shelves of natural history collections and were exhibited in public squares by charlatans.
