This engraving, found in Athanasius Kircher's two volume work on music, depicts Orpheus playing the hellhound Cerberus to sleep in order to gain passage to the Underworld. In classical sources, Cerberus was not usually so easily tamed: to the Greeks, he was a monstrous three-headed dog. A glance at Cerberus was said to petrify humans, and his bite was poisonous. Most Greek sources describe Cerberus as possessing three heads, as does Fluffy, the fearsome guard dog who blocks passage to the underground vault guarding the philosopher's stone. Spoiler alert: Harry and his friends take a cue from Orpheus's book and soothe Hogwarts' vicious pup by picking a drowsy tune.
Spanish physician Francisco Hernández published the first natural history of Mexico in 1651, and in it reproduces this desiccated dragon, said to have belonged to Cardinal Barbarini. Barbarini's specimen impressed the members of the early Italian Society of the Lynx, and a live rendering can be found in Ulisse Aldrovandi. Daydreaming Defense Against the Dark Arts students will be the first to notice that a dragon skeleton hangs from the ceiling of their classroom. As Gilderoy Lockhart drones on, imagine you're off hunting in Romania with Charlie Weasley.
