# Pliny on mammals

Pliny the Elder's Natural History Book VIII centres around the concept of zoology, and mainly that which pertains to terrestrial animals, including mammals, amphibians, reptiles, as well as some birds and insects. Pliny discusses these animals as being a part of specific categories, firstly starting with those he considers to be wild, including, but not limited to, elephants, snakes, lions, giraffes, rhinoceroses, lynxes, camels, leopards, hyenas, foxes, rabbits, skinks, beavers, frogs, seals, geckoes, chameleons, deer, reindeer, jackals, porcupines, bears, hedgehogs, squirrels, snails, crocodiles, and lizards. He then goes on to cover those he considers to be domesticated, such as dogs, horses, donkeys, mules, oxen, sheep, goats, and pigs. Following this, he mentions animals that are “half-wild," or what he considers to be wild varieties of commonly domesticated animals, including boars, chamoises, ibexes, oryxes, antelopes, monkeys, and hares, as well as those that are “neither wild nor tame but of a character intermediate between each," such as swallows, bees, dolphins, and mice. Lastly, on various occasions he mentions animals that would be considered mythological, such as unicorns, pegasi, basilisks, and werewolves, of which he considers only the existence of werewolves to be obviously fantastical.
Pliny describes the anatomical traits of these various animals in a way that champions morphology over scientific specificity, visualizing each animal by describing it as an amalgam of other animal parts.
Throughout these board sections, Pliny applies the behavioural topics of cognition, symbiotic relationships, and the relevance of animals to humans. However, the perspective through which Pliny observed animals and their various attributions was biased by the fact that he lived during the first century AD (23-79 AD), and thus was subjected to the political, religious, and intellectual beliefs that were upheld in ancient Rome, such as Stoicism. Many of his observations prove to be factual, even by today's standards, while others are representative of period in which he lived.

## Cognition
### Intellectual capacity

Pliny spends many pages discussing the cleverness of elephants, describing them to be "the nearest to man in intelligence" and as having "virtues rare even in man," such as justice, wisdom, and honesty. Pliny even goes so far as to present various instances of elephant intelligence, such as some elephants who were known to have performed choreographed dances and walk on tight-ropes at a gladiatorial show given by Germanicus Caesar, one who had learned how to write, as reported by Mucianus, the phrase "'I myself wrote this and dedicated these spoils won from the Celts'" using the Greek alphabet, and one elephant who, after being beaten for not understanding the instructions for a particular task, was later found to be practicing the same endeavour. He even gives an example of elephants being able to sense human malevolency, in the way that they will remain calm and polite when faced with a human that means no harm, even having been known to show humans the way if they are lost, but will become fearful and quickly alert other elephants if the human is of ill-intent, which they ascertain by the smell of the human's footprints. The memory of elephant's is also a topic the Pliny discusses, providing the example of an elephant to was able to recognize an old man who many years prior, in its youth, had served as its trainer.
Further to this, Pliny also spends time discussing the ability of various animals to engage in the conscious contemplation of specific actions that help them to avoid being hunted or poached. For example, he covers elephants smashing their tusks on trees when cornered by ivory poachers, seals intentionally vomiting up their gall, a useful ingredient in drugs, and rennet, a cure for epilepsy, to avoid being killed in order to harvest them, and hedgehogs knowingly urinating over themselves to rot their hide, for which they are hunted, and thereby decrease its value.
The intelligence of elephants is not just observed in antiquity, but is also documented in the modern day by various scientific researchers. The concepts of elephant memory, learning, teaching, and intelligence, along with numerous other elements of elephant neuropsychology, are all discussed in Dr. Michael Garstang's book Elephant Sense and Sensibility: Behaviour and Cognition.
In addition to elephants, Pliny also places a great amount of focus on particular domesticated species, including dogs and horses which he describes as being the animals "most faithful to man." Pliny often praises a dogs' recognition of their master, their own name, a family member's voice, and locations, even saying that "no creature save a man has a longer memory" than a dog. Additionally, their uses in hunting and tracking are also highly valued. Meanwhile, Pliny states that "the cleverness of horses is beyond description," such that they have an unwavering docility and an understanding of their duty, whether that be to pull a chariot or to assist a javelin toss. The docility of Sybarite horses is stated to be so great that they will mourn the death of their masters who die in battle, even shedding tears at their loss.
Ann-Sofie Sundman's published work Dog Behaviour: Intricate Picture of Genetics, Epigenetic, and Human-Dog Relations presents the behaviour of dogs as having resulted from years of human-directed domestication, and thereby occupying very specific niche that requires interspecific social competence and the formation of strong bonds. Sundman states that dogs' ability to effectively socialize with humans was critical for their continued existance in an anthropogenic environment, and that their excellent abilites in communication, cooperation, and bonding are examples of this selective evoluntary niche. Human behaviours that dogs intrinsically recognize and respond to include eye contact, which results in the release of oxytocin for both the human and dog, and referential gestures like pointing.

### Emotional competence

Pliny the Elder describes elephants as not only exhibiting impressive brilliance with regards to their memory, learning, and methods of survival, but also with their capacity to feel emotions. Pliny outlines the ability of elephants to shame, such that in battle they offer their conquerer leaves and dirt, and their predilection towards modesty which forces them to mate only in secret. Addtionally, Pliny also comments on their morality by putting forward that elephants never engage in adultery or any of the intermale competition "that is so disastrous to the other animals." However, Pliny specifies that this is not due to a lack of emotion, and provides several examples of elephants falling in love with humans, and in one instance so intensely that the elephant refused to eat without the presence of its preferred person.
Pliny repeatedly refers to the distinct behavioural phenomena of animals feeling gratitude and respect towards humans. For example, he recounts the tale of a lion who, after having a painful bone pulled from its teeth, always brought any game it caught to its saviour, a female panther who guides a man out of the desert after he rescues her cubs from a pit, a snake who, after being formerly kept as a pet by a man, came to his aid when he was later ambushed by brigands, and a dog who continued to defend his deceased owner in battle despite being severely wounded.
Behavioural phenomena of this kind have also been noted to occur by modern researchers, such as Dr. Michael Garstang in his book Elephant Sense and Sensibility: Behaviour and Cognition. Within his work, Dr. Garstang discusses the concepts of morality, empathy, altruism, and emotions in elephants that are supported by various scientific articles from researchers around the world. Interestingly, Dr. Garstang and Pliny the Elder share the same opinion on elephant societal structure, both individually stating that elephants are among the most social of animals. Dr. Garstang verifies the idea that elephants have an immense capacity to feel and express numerous emotions, which they communicate through changing their behaviours and vocalizations. Changes to the frequency of an elephant's vocalizations has been directly connected to the intensity and quality of the emotions that they experience, such as how elephants have been observed to produce a particularly low-frequency call when exposed to death. Additionally, Garstang asserts that recognizable human emotions have been specifically observed at the David Sheldrick Wildlife Trust in Kenya, where caretakers feel that "they can detect smiles" on the elephants that are kept there, and he even recounts a story from 2012 in which two herds of elephants on the Thula Thula game reserve in Zululand, South Africa, individually traveled 640 km to Johannesburg where the funeral of the game reserve's founder, Lawrence Anthony, was taking place.

## Interspecies relationships
### Competition

Pliny states that elephants "hate the mouse worst of living creatures," and if they happen to find one in the fodder they are eating they will become disgusted. He also asserts that snakes are continuously at odds with elephants.
As well, it is suggested that "the greatest enemy of the snail is the lizard."

### Hybridization

As described by Pliny, it was apparently a practice of Indians to breed tigers with female dogs to obtain a fiercer animal, while it was a practice of the Gauls to breed wolves with dogs and the results of these matings then serving as the leaders of their dog packs.
Pliny states that lions can interbreed with leopards, and he also suggests that lionesses can mate with hyenas to produce a mythical species called the corocotta.

## Human relevance
### Domestication and companionship

Pliny frequently recounts tales of famous animals that were either devoted to their owners, exceptionally brave in battle, or hilariously amusing at the circus or coliseum, such as Alexander the Great’s famous horse, Bucephalus, who engaged in great feats of bravery during war and when adorned with a royal saddle would not let anyone else mount.

### Medicines and other animal resources

One point to note about Book VIII of Natural History is Pliny’s insistence on the beneficial effects of animal products for human health, which would now be considered homeopathy or folk medicine, as they do not have a scientific basis. Pliny’s medicinal substances cover a wide range of animals, internal and external organs, diseases, and purposes, and more often than not his claims about the effectiveness of a given substance are difficult to believe when one is studying them through a modern perspective. In Loren MacKinney’s article entitled Animal Substances in Materia Medica: A Study in the Persistence of The Primitive, he proposes that animal resources were commonly used for ancient medicinal practices within many civilizations, such as those found in Egypt, Greece, and Rome. In particular, MacKinney considers Pliny the Elder to be an influential source as to the use of natural remedies in the Roman Empire, and that Natural History is “one of the most comprehensive of all sources of information concerning the materia medica of the ancient world."
In terms of the supposed medicinal values present in various animal parts, Pliny states that the shedded skin of a gecko can cure epilepsy, the gall and rennet of a seal are useful for drugs and “epileptic attacks,” respectively, the right horn of a stag is imbued with a potent healing drug, goat liver can cure night-blindness, the skink can act both as an antidote to poisons and an aphrodisiac for males, the smell of burning deer’s horns can stop epileptic seizures, the consumption of venison prevents feverish diseases, and that bear fat is useful for preventing baldness.

### Historical influence

The Roman perspective and Stoicism were two major ideologies that likely informed Pliny’s mode of looking at the natural sciences, and thus how he contextualized them within the encyclopedic format of Natural History. The Roman consciousness held an idea of anthropocentricity, in which man was perceived to be the highest level of physical beings and that “the rest of creation existed to serve his needs." This belief might have influenced Pliny to write about animals in terms of their benefit to humans, such as in his recurring points on medicinal properties and domestication found within Book VIII. Stoicism put forward prevalent ethical ideals including “independence of mind” and “devotion to duty," which possibly affected Pliny’s opinions surrounding the intellectual capabilities of animals, their conscious opinions about humans, and their loyalty towards their owners.
Further to this, in his analyzing the narrative structure of Pliny, Thorsten Fögen asserts that the way that Pliny describes elephants is akin to the virtuosity of "good Roman citizens," and that elephants could serve as a representative for how humans should behave. Fögen also highlights how Pliny's aim in composing Natural History seemed to be centred around communicating the ethical components of animal behaviour through the discussion, as well as many examples, of their moral qualities and anthropomorphic traits.
Additionally, because of the expansion of the Roman Empire that was occurring during construction of the Natural History, new discoveries were being unearthed that contributed to the collective Roman fascination with “mirabilia," or things in the natural world that were unique, strange, and unusual. This may have contributed to Pliny’s inclusion of peculiar animals and odd animal behaviors.
