Woodblock print of a basilisk from Ulisse Aldrovandi, Monstrorum historia, 1642
In European bestiaries and legends, a basilisk (English pronunciation: /ˈbæzɪlɪsk/, from the Greek βασιλίσκος basilískos, "little king;" Latin Regulus) is a legendary reptile reputed to be king of serpents and said to have the power to cause death with a single glance. According to the Naturalis Historia of Pliny the Elder, the basilisk of Cyrene is a small snake, "being not more than twelve fingers in length," that is so venomous that it leaves a wide trail of deadly venom in its wake, and its gaze is likewise lethal; its weakness is in the odor of the weasel, which, according to Pliny, was thrown into the basilisk's hole, recognizable because all the surrounding shrubs and grass had been scorched by its presence. It is possible that the legend of the basilisk and its association with the weasel in Europe was inspired by accounts of certain species of Asiatic snakes (such as the King Cobra) and their natural predator, the mongoose (see "Rationalized accounts" below).
The basilisk is called "king" because it is reputed to have on its head a mitre- or crown-shaped crest. Stories of the basilisk show that it is not completely distinguished from the cockatrice. The basilisk is alleged to be hatched by a cockerel from the egg of a serpent or toad (the reverse of the cockatrice, which was hatched from a cockerel's "egg" incubated by a serpent or toad). In Medieval Europe, the description of the creature began taking on features from cockerels.
One of the earliest accounts of the basilisk comes from Pliny the Elder's Natural History, written in roughly 79 AD. He describes the catoblepas, a monstrous cow-like creature of which "all who behold its eyes, fall dead upon the spot," and then goes on to say,
"There is the same power also in the serpent called the basilisk. It is produced in the province of Cyrene, being not more than twelve fingers in length. It has a white spot on the head, strongly resembling a sort of a diadem. When it hisses, all the other serpents fly from it: and it does not advance its body, like the others, by a succession of folds, but moves along upright and erect upon the middle. It destroys all shrubs, not only by its contact, but those even that it has breathed upon; it burns up all the grass too, and breaks the stones, so tremendous is its noxious influence. It was formerly a general belief that if a man on horseback killed one of these animals with a spear, the poison would run up the weapon and kill, not only the rider, but the horse as well. To this dreadful monster the crow of a rooster is fatal, a thing that has been tried with success, for kings have often desired to see its body when killed; so true is it that it has pleased Nature that there should be nothing without its antidote. The animal is thrown into the hole of the basilisk, which is easily known from the soil around it being infected. The weasel destroys the basilisk by its odour, but dies itself in this struggle of nature against its own self."
Isidore of Seville defined the basilisk as the king of snakes, due to its killing glare and its poisonous breath. The Venerable Bede was the first to attest to the legend of the birth of a basilisk from an egg by an old cockerel, and then other authors added the condition of Sirius being ascendant. Alexander Neckam (died 1217) was the first to say that not the glare but the "air corruption" was the killing tool of the basilisk, a theory developed one century later by Pietro d'Abano.
Albertus Magnus in the De animalibus wrote about the killing gaze of the basilisk, but he denied other legends, such as the rooster hatching the egg. He gave as source of those legends Hermes Trismegistus, who is credited also as the creator of the story about the basilisk's ashes being able to convert silver into gold: the attribution is absolutely incorrect, but it shows how the legends of the basilisk were already linked to alchemy in 13th century.
Geoffrey Chaucer featured a basilicok (as he called it) in his Canterbury Tales. According to some legends, basilisks can be killed by hearing the crow of a rooster or gazing at itself through a mirror. The latter method of killing the beast is featured in the legend of the basilisk of Warsaw, killed by a man carrying a set of mirrors.
Stories gradually added to the basilisk's deadly capabilities, such as describing it as a larger beast, capable of breathing fire and killing with the sound of its voice. Some writers even claimed that it could kill not only by touch, but also by touching something that is touching the victim, like a sword held in their hand. Also, some stories claim its breath is highly toxic and will cause death, usually immediately. The basilisk is also the guardian creature and traditional symbol of the Swiss city Basel.
The basilisk was, however, believed to be vulnerable to cockerels; therefore travellers in the Middle Ages allegedly sometimes carried cockerels with them as protection.
Leonardo da Vinci included a basilisk in his Bestiary, saying it is so utterly cruel that when it cannot kill animals by its baleful gaze, it turns upon herbs and plants, and fixing its gaze on them withers them up. In his Notebooks, he describes the basilisk, in an account clearly dependent directly or indirectly on Pliny's:
- This is found in the province of Cyrenaica and is not more than 12 fingers long. It has on its head a white spot after the fashion of a diadem. It scares all serpents with its whistling. It resembles a snake, but does not move by wriggling but from the centre forwards to the right. It is said that one of these, being killed with a spear by one who was on horse-back, and its venom flowing on the spear, not only the man but the horse also died. It spoils the wheat and not only that which it touches, but where it breathes the grass dries and the stones are split.
Then Leonardo says the following on the weasel: "This beast finding the lair of the basilisk kills it with the smell of its urine, and this smell, indeed, often kills the weasel itself."
According to the tradition of the Cantabrian mythology the ancient Basiliscu (as they called it) has disappeared in most of the Earth but still lives in Cantabria although it is rare to see it. This animal is born from an egg that lays an old cock just before his death a clear night and full moon exactly at midnight. Within a few days, the egg shell, which is not hard, but rather soft and leathery, is opened by the strange creature that already has all the features of an adult: legs, beak, cockscomb and reptilian body. Apparently this strange creature has an intense and penetrating fire in its eyes that at the animal or person who gazes directly upon it would die. The weasel is the only animal that can face and even attack it. It can only be killed with the crowing of a rooster so, until very recent times, travelers were carrying a rooster when they ventured into areas where it was said that the Basilisks lived.
Literary references 
The basilisk appears in the Bible in Isaiah 14:29 in the prophet's exhortation to the Philistines reading, "Do not rejoice, whole country of Philistia, because the rod that beat you has broken, since the serpent's stock can still produce a basilisk, and the offspring of that will be a flying dragon." The King James version of the Bible states "out of the serpent's root shall come forth a cockatrice, and his fruit shall be a fiery flying serpent."
In Psalm 91:13: "super aspidem et basiliscum calcabis conculcabis leonem et draconem" in the Latin Vulgate, literally "You will tread on the lion and the dragon,/the asp and the basilisk you will trample under foot," translated in the King James Version as: Thou shalt tread upon the lion and adder: the young lion and the dragon shalt thou trample under feet," the basilisk appears in the Latin Vulgate, though not most English translations, which gave rise to its inclusion in the subject in Early Medieval art of Christ treading on the beasts.
In William Shakespeare's Richard III, a widow, on hearing compliments on her eyes from her husband's brother and murderer, retorts that she wishes they were those of a basilisk, that she might kill him. In Act II, Scene 4 of Shakespeare's Cymbeline, a character says about a ring, "It is a basilisk unto mine eye, Kills me to look on't."
Similarly, Samuel Richardson wrote in his famous novel Clarissa; or the history of a young lady: “If my eyes would carry with them the execution which the eyes of the basilisk are said to do, I would make it my first business to see this creature.” Another famous reference to the basilisk is found in John Gay’s "The Beggar's Opera" (Act II, Air XXV):
- Man may escape from Rope and Gun;
Nay, some have out liv'd the Doctor's Pill;
Who takes a Woman must be undone,
That Basilisk is sure to kill”.
Jonathan Swift alluded to the basilisk in a poem:
- See how she rears her head,
And rolls about her dreadful eyes,
To drive all virtue out, or look it dead!
‘Twas sure this basilisk sent Temple thence …
Alexander Pope also wrote that “The smiling infant in his hand shall take/ The crested basilisk and speckled snake” (Messiah, lines 81–82). In the chapter XVI of The Zadig, Voltaire mentions a basilisk, “an Animal, that will not suffer itself to be touch'd by a Man”. Percy Bysshe Shelley in his "Ode to Naples" alludes to the basilisk:
- Be thou like the imperial basilisk,
Killing thy foe with unapparent wounds!
Gaze on oppression, till at that dread risk,
Aghast she pass from the earth’s disk.
Fear not, but gaze,- for freemen mightier grow,
And slaves more feeble, gazing on their foe.
Shelley also refers to the basilisk in his poem "Queen Mab:"
- "'Those deserts of immeasurable sand,
Whose age-collected fervors scarce allowed
Where the shrill chirp of the green lizard's love
Broke on the sultry silentness alone,
Now teem with countless rills and shady woods,
Cornfields and pastures and white cottages;
And where the startled wilderness beheld
A savage conqueror stained in kindred blood,
A tigress sating with the flesh of lambs
The unnatural famine of her toothless cubs,
Whilst shouts and howlings through the desert rang, -
Sloping and smooth the daisy-spangled lawn,
Offering sweet incense to the sunrise, smiles
To see a babe before his mother's door,
Sharing his morning's meal
with the green and golden basilisk
That comes to lick his feet." --Part VIII
Charles Dickens uses the Basilisk to describe Mrs. Varden's eternally angry and hideous housemaid, Miggs, in Barnaby Rudge: "But to be quiet with such a basilisk before him was impossible. If he looked another way, it was worse to feel that she was rubbing her cheek, or twitching her ear, or winking her eye, or making all kinds of extraordinary shapes with her nose, than to see her do it."
Modern reuse 
Basilisks have been reimagined and employed in modern fantasy fiction for books and role-playing games, with wide variations on the powers and weaknesses attributed to them. Most of these depictions describe a reptile of some sort, with the power to kill its victims with a direct stare and petrify through an indirect one.
Reuse in science fiction and popular culture 
Basilisks figure in the work of David Langford, to describe a (fictional) class of image or sensation which causes death or harm to anyone who views it. Langford's fictional basilisk images, or BLITs, are so deadly to the characters that all information about them, including the death toll when they first appear in the story, is classified; however, each of them is given a name or number, and a reasoning common to such stories is provided.
Basilisk: The Kouga Ninja Scrolls (バジリスク 甲賀忍法帖 Bajirisuku Kōga Ninpōchō , 2003) is a Japanese manga and anime series. The manga was authored by Masaki Segawa and published in Japan in 2003 and 2004, based on the novel The Kouga Ninja Scrolls by Futaro Yamada published in 1958. The title Basilisk would refer to the main characters Kouga Gennosuke's and Muroga Hyouma's ability to reverse the homicidal intent of anyone who meets his stare directly--effectively causing them to kill themselves--and Oboro's power to neutralize the techniques of any ninja who meets her stare directly.
In Star Wars, two weapons are known as the Basilisk. The Mandalorians used a type of battleship known as a Basilisk. Admiral Natasi Daala had a fleet of four Star Destroyers, one of which was called the Basilisk. It was destroyed by the fallen Jedi Kyp Durron, nearly killing Daala herself.
In the fantasy novel The Son of Neptune, the Gigante Polybotes's hair was covered with basilisks. After the goddess Iris opposes him, the Gigante throws three basilisks out to guard her home. In order to escape, the demigod Frank Zhang fights them off with his spartus ally Gray. Basilisks reappear at the final battle. However, this time, Frank has learned to use Periclymenus' power. He transforms into a weasel, the basilisks' mortal enemy, and defeats them.
Reuse in Harry Potter 
The basilisk appears in J. K. Rowling's Harry Potter books, most notably in Harry Potter and the Chamber of Secrets, where it is described as a large serpent whose direct glare causes instantaneous death. In the final installment of the series, Harry Potter and the Deathly Hallows, Ronald Weasley and Hermione Granger venture into the Chamber of Secrets in order to destroy the cup of Helga Hufflepuff(diary of Thomas Riddle), which Voldemort had turned into a Horcrux, with a fang of the dead basilisk.
In Rowling's book Fantastic Beasts and Where to Find Them, it is said that a basilisk is a green serpent that can grow up to fifty feet in length, the male being identifiable by the scarlet plume upon his head. It states that basilisks are believed to live for up to 900 years, and are only controllable by Parselmouths, people with the ability to speak snake tongue (known as Parseltongue).
Reuse in science 
Mythological concepts are sometimes co-opted in biological science to name animals, such as with "vampires", "lemures", "sirens", "dragons", and "harpies". "Basilisk" in science refers to Basiliscus, a South American genus of lizard containing four species.
