Over his lifetime, Herpo invented many vile curses. He is best known as the first wizard to hatch a Basilisk. He was also the first wizard known to successfully create a Horcrux, perhaps having designed the ritual himself. Accordingly, he must have committed murder to split his soul, though it is unknown who he killed.
Magical abilities and skills
- Dark Arts: Herpo was known as one of the most powerful and influential Dark Arts practitioners in history. Herpo is the first wizard to have ever successfully created a Horcrux and is possibly the wizard who invented the process by which to do this. The creation would have left his soul unstable, and rendered him less than human.
- Spell inventor: Invented many vile curses, which earned him his well-deserved reputation.
- Parselmouth: One of the earliest known Parselmouths, an uncommon gift to speak with snakes, which has been often connected to the Dark Arts.
- Basilisk breeder: First wizard to have discovered that hatching a chicken egg under a toad will create the King of Serpents. He managed to control it with Parseltongue, thus initiating one of the few cases of a wizard "domesticating" a XXXXX-class creature (known wizard-killer that cannot be tamed).
- In Ancient Greek, ἑρπετόν (pronounced "herpeton") means "creeping animal". In modern times, herpetology is the study of amphibians and reptiles. Basilisks are snakes, and thus reptiles, and Parseltongue is the language of snakes.
- In Ancient Greek, Herpo's name would be "῾Ερπων ὁ δεινός" (pronounced "Herpōn ho deinos").
Behind the scenes
- It is unknown when or under what circumstances Herpo the Foul died or his Horcrux was destroyed, assuming that these things did happen. If his Horcrux was never destroyed it is possible he is still alive, possibly as a wandering spirit in a state that Horace Slughorn described as being worse than death.
- If Herpo did indeed die, it is unknown whether his soul had shared a fate similar to that of Tom Riddle after the latter's death in 1998, assuming he never repented to repair his damaged soul.
- Herpo the Foul could possibly be an ancestor of Salazar Slytherin due to his dark abilities.
- Herpo the Foul's features are distinctly snakelike, though not nearly as much as Voldemort's. This suggests that snakelike mutations are indeed a direct effect of horcrux-making.
