    Snake’s Cultural Impact

    Let’s discuss the cultural impact of snakes. Snakes form an important part of many cultures in the world, both modern and historical. Ophidiophobia (phobia of snakes) is commonplace. Last week, we discussed the potential dangers certain snakes pose. The main risks include venomous bites and the largest constrictors. Non-venomous snakes are not a threat to humans.

    Snake Charming

    You will know this from various cartoons and movies. Snake charming is an Indian roadside show where the charmer plays a flute-like instrument and the snake responds to the music. Typically, the Indian cobra species.

    The snake is actually responding to the movement of the instrument, they lack external ears so they don’t hear in the conventional sense. Animal welfare laws prohibit snake charming.

    Snake Catchers

    The Irula tribe from India have been catching snakes for generations professionally. The snake skin industry was outlawed in 1972. The Irula tribe now catch the snakes to milk their venom. The venom is collected and used for producing antivenom, biomedical research and other medicinal products.

    There are modern day experts elsewhere in the world, who specialise in catching snakes both for study and to remove them from homes and property.

    Consumption

    Many people eat snakes, especially in Asia: China, Taiwan, Thailand, Indonesia, Vietnam and Cambodia. Snakes are believed to have health benefits and aphrodisiac properties. Snake wine, which is wine infused with whole snakes, is used in Chinese traditional medicine.

    Pets

    People keep snakes as pets, especially the more docile smaller snakes like the corn snake and the ball python. Snakes require specialist housing for optimum health but usually only need fed once every week or two. You need to seek expert veterinary care for snakes as well, not all vets are knowledgable or comfortable handling them.

    Symbolism and Mythology of Snakes

    Ancient Mesopotamia

    Nirah means ‘little snake’ in Sumerian. Nirah is a messenger god and may be lord of the underworld. Sumerian art features representations of two intertwined serpents. Ancient deities iconography in Assyria and Babylon feature snakes.

    Hopi Tribe of Arizon

    The Hopi Native American tribe celebrate snakes as a symbol of fertility. They release snakes into the fields to guarantee good crops. So they represent the umbilical cord joining all humans to mother Earth.

    Egypt

    Ancient Egyptian iconography commonly incorporates snakes. The Nile Cobra adorns the crown of the pharaoh. Snake iconography associated with Ra, Wadjet, Renenutet, Nehebkau and Meretseger.

    More sinister purposes for snakes exist in Ancient Egypt – using them to murder an adversary or to comit a ritual suicide. Cleopatra is famous for allowing an asp (Egyptian Cobra) to bite her, according to popular belief.

    Ouroboros

    Found in Ancient Egyptian iconography and Greek magical tradition, the symbol of a snake eating its own tail. Gnosticism, Hermeticism and alchemy adopted the ouroboros icon.

    The ouroboros represents the eternal cyclic renewal, or a cycle of life, death and rebirth. Snake’s shed their skin as they grow, hence this is representative of the transmigration of souls or immortality.

    The act of biting its own tail is a fertility symbol in some religions: the tail is a phallic symbol and the mouth is a yonic or womb-like symbol. So, the ouroborous represents sexual intercourse and reproduction.

    Ancient Greece: Medusa

    The legend of Medusa depicts a monster with snakes for hair that can turn those who look at her into stone. The hero Perseus slayed Medusa. She had two sisters, Stheno and Euryale who were both gorgons as well. Her image symbolises warding off evil.

    In Ovid’s Metamorphoses the tale of Medusa is a bit different by comparison. Medusa, a priestess of Athena and suffered sexual assault by Poseidon, the god of the sea. Athena turned her into a gorgon after this. Some say as punishment, others believe it was so she could protect herself. Because of this, Medusa is an important symbol for sexual assault survivors in the modern day.

     Asclepius

    The Greek god of healing, Asclepius, represented by a rod or staff with a serpent wrapped around it. The sick and injured went to Asclepius’ temples for healing and care. Hence, the staff of Asclepius became a symbol for medicine.

    Similarly, Hermes’ staff, Caduceus has wings and two serpents intertwined around it. With a V included in the symbol, it represents veterinary medicine. Hermes was messenger to the Olympian gods.

    India

    Indian traditions and deities feature snakes a lot. Shiva has a cobra around the neck. Vishnu is sometimes depicted as sleeping on a seven-headed snake or within the coils of a serpent.

    Temples dedicated to cobras called Nagraj are common. Snakes symbolise fertility and people celebrate them during the Hindu festival of Nag Panchami.

    China

    The Chinese Zodiac features snakes as one of the twelve celestial animals. 2025 is the year of the snake, hence my choice of topic for this month. Snakes associate with traits like intelligence and unscrupulousness. Ancient China related snakes to the river deities.

    Christianity and Judaism

    The Garden of Eden

    We can’t talk about snakes in culture and society without discussing this. In the book of Genesis, a serpent tempts Eve to eat the forbidden fruit from the Tree of Knowledge. God throws Adam and Eve out of the Garden as punishment and this confers the concept of ‘Original Sin’ on humanity. Whether you believe it or not, nobody can deny the importance of this story on shaping our society and culture. Genesis doesn’t name the serpent, but it is a common belief that the serpent is the Devil.

    Moses

    In the book of Exodus, Moses turns his staff into a snake as proof of God’s power. In the book of Kings, God instructed Moses to create the Nehushtan – a bronze snake on a pole that cured people of snake bites in the desert.

    Satan

    The final book in the New Testament, the book of Revelation contains the final mention of serpents in the Bible. There, serpents are symbolic of Satan, the fallen angel who tempts people towards sin. He plays a role in the apocalypse described by the book of Revelation.

    It’s clear that snakes represent evil and sin in Christianity. There is less of this in Judaism and Islam.

    Conclusion

    It’s clear that snakes play an important role in a lot of cultures. They can symbolise fertility, the cycle of life, rebirth, evil and temptation. People fear and revere snakes across the world. Often maligned and misunderstood, yet they have played an important role in shaping society as it is today.

    However, snakes also represent healing, recovery and caring for people and animals alike. I love snakes, they are fascinating creatures and get a bad rap. They have personalities, unique abilities and an important place in the ecosystem.

    I hope you enjoyed this summary of the snakes cultural impact and why they matter so much. They have a number of representations which you can use in your writing to symbolise different things. As always, if you have any thoughts or questions, I’d love to hear them.

    Snake Senses and Physiology

    Snake Eyes

    No, not when you roll a one on a dice. Actual snake eyes, on actual snakes. We’re talking about snake senses and physiology. Snakes generally have good vision, some of them have slitted pupils like cats. All snakes lack eyelids, instead they have a clear scale covering the eye called the spectacle.

    You can tell if a snake is due to shed its skin because the eyes go cloudy. Fluid is secreted under the old skin to lift it off to be shed, and this causes the cloudiness. Snakes are vulnerable during this process so they can be more aggressive than usual if disturbed as they are blind.

    Some snakes also have the ability to ‘see’ infrared to find prey in the dark. Pythons, boas and pit vipers have indentations on their upper lips called the ‘labial pits’ which sense infrared. The image shows the little holes along the top lip of the snake, these are the labial pits. Each group of species evolved these things separately, and they are also believed to play a role in temperature regulation as well as hunting. Like night-vision goggles essentially, isn’t that cool?

    Snake Tongue and Sense of Smell

    Snakes use their tongues to detect scents. So when you see their little forked tongue flicker out, that’s what they’re doing. Most people know this. The tongue collects airborne particles and feeds them to the ‘vomeronasal organ’ also known as the ‘Jacobson’s organ’ inside the mouth. This organ is present in most animals, but not humans and aids in scent detection, especially pheromones. So it’s important for detecting prey, predators and potential mates.

    Snake Skin

    Snake skin is highly specialised to protect their bodies and provide grip for their unique form of movement. Lacking legs means that snakes must move flat along the ground, so their scales help them grip the surfaces. Many species can make use of this to climb trees as well and even smoother surfaces to an extent.

    Snakes are covered in scales – some are smoother, others are ‘keeled’, meaning they have a ridge down the centre. Their dorsal scales, the upper body scales, are usually loosely diamond-shaped and arranged in interlocking rows. Their ventral scales (belly scales) are usually singular and wide until the vent, after which they are paired until the end of the tail.

    Ecdysis means shedding of the skin. This is something all snakes go through as they grow. Younger snakes will shed more frequently than older snakes. The process takes a bit of time. The new scales grow underneath, and fluid lifts off the old scales.

    This is when the spectacle goes cloudy. The snake will not feed during this process, but usually will feed soon after. Normally the snake sheds its skin in one long piece. They rub their chin on something rough like a rock or tree, and slowly wiggle their way out of the skin.

    Rattlesnakes have a unique set of scales on the end of their tails. They build up from previous sheds and form a hardened collection of scales which makes a sound when shaken. They use this as a warning to predators, and it gives them the name.

    Reproduction

    Snakes reproduce sexually, with internal fertilisation. Most species lay a clutch of eggs, which are left to hatch and fend for themselves. Some species stay with the eggs and care for them until they hatch, like pythons.

    A few species are classed as ‘ovoviviparous’, which means they keep the eggs inside until they hatch and are ‘born’. So this is a kind of inbetween egg layers and live birthers, if you will. Rattlesnakes are an example of this.

    There are a couple of species that have true live births. The boa constrictor and green anaconda both have placentas as well as yolk sacs for their young and give birth to live snakes. They don’t produce eggs.

    A phenonemon called parthenogenesis is seen in a couple of snake species. Parthenogenesis is a form of asexual reproduction, where a female animal can produce fertile eggs without mating. Copperheads and Cottonmouths are capable of this, although they can also do it the old-fashioned way.

    Feeding Snakes

    Snakes are carnivores and eat animals, occasionally eggs but mostly smaller animals. They eat their prey whole and take a while to digest their meal. Some even eat other snakes in some cases. Snakes can’t bite off or chew their food, and are specialised towards this as discussed last week.

    Snakes tend to be ambush predators and will strike quickly to catch their prey. Venomous snakes bite and inject venom to kill their prey before eating it. Other snakes will use constriction – wrapping their bodies around the prey and squeezing it until it dies before they slowly swallow it.

    They then go and rest to digest their prey. Ideally they would keep their body temperature around 30 °C (86 °F) and as they are ectothermic they will move to a location to keep their temperature around that level. It takes some time to digest but they can digest everything but hair, feathers and claws. These indigestible parts are excreted within the faeces of the snake. Snakes don’t eat often, depending on the species and size of the previous meal this can range from once a week to a couple of times a year! Younger snakes need to eat more frequently so they have energy for growth. In captivity it’s important not to overfeed snakes. But they can also go a long time without food as well, over a year in some cases.
