Disease in Imperial Rome

The Roman Empire has garnered itself a mostly positive reputation for the complicated sewer systems that ran underneath many of its cities. Roman engineering brought water to the city from the Alban Hills using an aqueduct system implemented in 312 BC [1] Although primitive forms of sewage systems have existed in Rome since pre-imperial times, these were mostly primitive drains that led to the nearby rivers and streams. Another source of water that proved to be dangerous was the Tiber River, which the Roman Army drank from, contributing to their vulnerability to many diseases.[2] As the skills of engineers continued to grow, the complexity of the sewers did as well. For example, the Cloaca Maxima was one the first complex and expansive sewer systems that ran under Rome.[3] The sewer systems had an extremely complex design and for the most part succeeded in providing Romans with adequate amounts of relatively clean water for consumption and bathing.

While the sewage systems of Imperial Rome may been engineering marvels and set precedents, there were still major flaws in Roman sewer systems. The population of Rome and other cities in the empire steadily grew, increasing the strain on the waste systems. However, due to the public health laws concerning street disposal of public waste, most of the large outbreaks and public health crises cannot be directly attributed to the sewer systems of Rome. There were many other more serious factors that added to the catastrophe of the major public health crises of Imperial Rome. Since most sewer systems were privately owned, they were privately maintained, and in turn neglected. Instead, citizens would turn to their latrines; if they lived on anything but the ground floor they would even throw their excrement onto the street. This led to sewage being exposed to flies, dogs, and bacteria, all of which helped spread disease among Romans. Although it is unclear what specific diseases were caused by the toilets in Imperial Rome due to the lack of clarification in ancient texts during that time period, it is likely that a multitude of intestinal diseases could have been caused through the lack of sanitation. Some examples of possible diseases includes dysentary, typhoid fever, and other types of diarrheas .[4]Another infamous hazard to health was the lead piping used to transport water throughout the city. Modern science has proven the devastating effects of lead, especially in regard to fertility. Some experts believe this may have been a leading factor in the population decline in the latter Imperial period. In fact, a study by Dr. Arthur Aufderheide of the University of Minnesota revealed that "Romans had 10 more times lead in their bones than modern Americans."[5]

Studies indicate that lead was very prominent in Roman beverages. This is mostly due to the lead-based storage containers that were popular during the time.[6] Some scholars speculate that the levels of alcohol consumed on a daily basis were more to blame for the health ailments of the aristocrats of Rome, with the average consumption rate being approximately 3 bottles of wine a day.[6] It is important to note that the practice of diluting wine was common as the source mentions, and that undiluted wine was considered barbaric. In fact, the Romans would typically mix one part wine to two parts of water. It was also common practice to hinder the sweetness of wine through the use of sea water or to warm the wine. [7]

The city of Rome also faced a major problem with street garbage and the build up of trash. Poets and satirists often made the Roman litter problem the subject of jokes and writings, with descriptions of trash being everywhere, including in Roman households and on the floor.[8] The lack of sanitation on the streets and households of Rome contributed to disease and sickness. Trash items ranged from discarded household items to actual human waste, meaning contamination chances were very high. The Romans realized this was becoming a problem, and a series of laws and other measures were taken to limit garbage build up in the streets. Most of these measures were implemented in order to prevent pedestrian casualties from waste falling on them, however these measure also increased the public health by eliminating the waste from the immediate city.[6] There is evidence to suggest that they allowed waste carriages to go throughout the city and collect waste during hours in which other modes of transportation were banned.[8] This strategy did not completely solve the problem, as most of the waste was just moved outside the city limits meaning the risk for contamination and odor is still present.

Public and private bath houses were common in Rome during the Imperial period of Rome. Commonly referred to as Thermae, these bath houses varied widely, but most had similar bathing processes. Occupants would exercise, use a variety of saunas and cooling rooms, and sometimes swim in a pool.[9] Even an imperial-version sauna was created for cleansing the body of toxins.[10] The hours typically started at lunchtime and closed at dusk and was open to everyone, with only a small fee required to enter. Bath houses were typically located near the forum of Roman towns. [11]Due to the high poverty rate in Rome, it was uncommon for the middle class citizens to own a private bath, according to journalist Jay Stuller. The heated bath water was not always chemically cleansed or filtered with chemicals such as chlorine, causing bacteria to thrive and spread. When Christianity came to Rome, it viewed the public nudity of the bathing system as debauchery and therefore it became frowned upon. While the bathing system may not have been pristine, abstaining from cleanliness altogether brought upon many more potentially fatal diseases, especially in infants.

From analyzing public latrines in the ash-preserved city of Hercaleum, researchers were able to determine the diet to be largely derived from a variety of fish species. The diet of the town seemed to be supplemented with spices, some originating from India. It seems that the occupants of Hercaleum had a well rounded diet and although the diet of Roman citizens may have changed depending on the region, it seems that food was accessible from a variety of places that the Romans traded with.[12]

In contrast to today's diet, Romans ate little meat. According to scholar Linda Gigante, they consumed large amounts of grain, fruits, and some vegetables. The poor were given monthly supplies of grain and hardly had money to pay for anything else. Due to this, many Romans suffered from malnutrition and multiple vitamin deficiencies. Even those who had money for food did not always have the best choices. There was no food and drug regulatory agency in ancient times, so low food standards brought contamination and parasites.

Rome's population was unprecedentedly large in the ancient world, reaching 1 million during the high point of the Empire.[13] This was much larger than the other major cultures that co-existed and predated the Romans. Paired with the poor living conditions that many Romans experienced, the city was a perfect breeding grounds for disease. In the poor boroughs of Rome, tight living conditions and filth increased the spread of disease. The Antonine and Cyprian plagues were transmitted through touch, which only added to the severity of the plagues, especially in areas of poverty.

Rome had an extremely high population, and remnants of buildings suggest the average living space was very small.[14] Many people crammed into small spaces led to very high rates of infection for transmittable diseases. The Antonine and Cyprian plagues were transmitted through touch, so a dense population rate would contribute highly to their spread.

Deforestation of Rome's cities, particularly near the Tiber River, led to higher disease rates. The causality is as follows: deforestation lead to a rising water table, which increased marshes. This increased the larva in Rome, and in turn increased disease borne from blood-sucking bugs. Mosquitoes and other vectors were carriers of various diseases, such as malaria and the Ross River virus.[15]

The air in Rome was undoubtedly polluted, with many sources remarking on the odours that could be found walking around the city. There were multiple sources of Rome's air pollution, open fires and human waste just being some of it. This degree of waste also attracted rodents and pests of all natures, only adding to the number of concerns for public health. It wasn't until the rule of Emperor Domitian that air pollution was attempted to be taken care of within the city. Laws were passed with the threat of fines and regulations that helped to attempt and clean the air. Diseases such as cholera were rampant and can be directly attributed to the waste pollution as well as air pollution.

The Antonine Plague is certainly one of the most infamous plagues in Roman history. Having no immunity to the plague, which was brought from soldiers returning form campaign in Western Asia, lead to catastrophic results for the Romans.[16] The main symptoms included diarrhea, skin sores and irritations and sore throats. The diseased suffered from it for around two weeks before they either died, or recovered and in turn developed immunity from further contraction.[17] The legions were hit by the plague hard. With cramped conditions and living quarters, the disease spread violently, reportedly decimating the Roman forces. Evidently, the plague hit the civilian population of the City and Empire of Rome. Emperor Marcus Aurelius implemented several changes which suggest the dire status of the Empire. This included loosening the regulations for membership of higher councils in multiple important settlements throughout the empire, including Athens.[16] Egypt was another region that saw catastrophic loss in the populations of their cities. This was demonstrated in the papyrus scripts documenting the loss in revenue from the massive decrease in population. The entire empire was facing hardship from the plague. Public building projects ceased in many of the provinces' major cities, including London. This all simultaneously happened while the empire faced attacks from the Sarmatians in the east. It is estimated that up to 15% of the Roman population was wiped out during the ten year plague, including Emperor Marcus Aurelius in 180 CE. It is widely believed that the plague was what is now known as smallpox. This can be determined largely due to the notes and commentary from famed Greek physician Galen. It is estimated that the Antonine Plague's impact on the Roman Empire was devastating and the effects lasted for centuries after the fact, some historians arguing that it permanently crippled the Empire and assisted in its downfall.

The Antonine Plague was named after the emperor whose reign it originated in, Aurelius Antoninus, according to Louise Cilliers and Francis Retief. Historical sources suggest that Roman soldiers returning from campaign in Mesopotamia spread the disease, which lasted from 165-180 AD.[18] Based on the written observations of fever, diarrhea, and boils by the Greek physician Galen, historians infer that smallpox caused the plague.[19] Including substantial army deaths, the outbreaks decimated an estimated two thirds of the Roman population, killing roughly 2000 people per day.[20]

Cilliers and Reteif go on to describe that the second great plague affecting Rome. The Plague of Cyprian, (249-262 AD) caused widespread shortages across the empire, and was one of the major contributing factors to the Crisis of the Third Century although considered to be separate from the Antonine Plague, it is very similar and also believed to have originated from smallpox, or perhaps measles. Saint Cyprian makes the most vivid description of the effects of the disease as dysentery, loss of motor skills, and of course fever, and in turn has the disease named after him (also possibly due to the oppression of Christianity at the time). The Plague of Cyprian actually increased the membership of the Catholic Church as the Roman populace suffered their second major plague, faith was being lost in Rome and found in the Christian God. The plague spread from Asia into Alexandria, moving its way into major port cities and soon throughout the entire empire. Accounts in North Africa from the Christians note the sheer death toll and daily events of death. Notably, his list does not include skin rashes or swelling, which is the main separation from the bubonic plague and Antonine Plague.[21] The plague did exhibit some unique symptoms including haemorrhages, giving the plague a bloody and infamous reputation.This plague was very widespread, possibly originating in Ethiopia and spreading to Scotland. With the skin contact-spreading nature of the disease and the crowded civilization style in Rome, the death toll was tremendous in the empire.[20]

Morbus Gallicus, better known in modern times as syphilis, or the "French Disease" was not prominent in ancient Europe but with recent bone studies, it has been found that a type of European treponematoses bacteria may have even affected children.[22] However, according to an article published by Kristin Harper in 2008, ancient European civilizations may have suffered from a related form of the bacteria but not venereal syphilis itself, which may have had its origin in the pre-Columbian Americas.[23] The term ‘syphilis" was coined later on by a 15th-century Italian poet Girolamo Fracastoro, who wrote an epic poem of a boy named Syphilus who insulted Apollo, and was in turn punished with the disease. During the Medieval and Renaissance periods the likely mutated forms of the treponematoses resulted in epidemics.[24]

The earliest known case of malaria is from Roman DNA dated to 450 AD. An excavation of a village shows signs of a serious malaria problem, with bone tests and traces of honeysuckle, a plant used to treat fevers. Also noted is that the area was a "zone of pestilence".[25] Deforestation and sanitation issues were the main causes of malaria.

Mentagra, notably thought by the Imperial Romans to be spread by kissing, was a skin disease most commonly starting in the chin and moving on to the entire face and sometimes other body parts. The aesthetic factor was very unappealing, while the disease was hardly adverse to health at all. Even though it was not dangerous, Romans ironically went as far as scar-inducing cauterizations to rid them of the abhorrent disease.[20]

Respiratory diseases, most prominently anthracosis, were common due to pollution in Roman homes according to Professor Luigi Capasso. Carbon was constantly produced with their lamps, cooking, and fireplaces. The carbon produced lesions on their lungs, apparent in bone studies (made possible by the well-preserved bodies stored under the remnants of a volcanic eruption of Vesuvius) and even a study on a Roman mummy.[26]

The highly experienced medical personnel were focused on the military, which was often the most vulnerable group to any given disease. Dioscorides served under Emperor Nero, experimenting with surgical techniques and medicinal herbs. Pliny the Elder also had a strong focus on botany, well known for his herbal knowledge. Each specialist had different methods and the ways of treating diseases was very varied, causing most treatments to be extremely useless due to the lack of consistency.

Galen, perhaps the most prominent Roman physician, studied anatomy as well as herbal remedies. Galen's contributions to medicine mainly consisted of his detailed book series that aided in future doctors' studies of practical medicine. As far as his contribution to medicine in the ancient world, he expanded the knowledge of medicine through using similar methods to Hippocrates, which strayed away from the mythical methods of medicine that proved to be ineffective. These methods that he practiced included studying anatomy and using many different procedures in an attempt to find reliable ways of treatment. [28]

Natural medicine was of great importance, seeing as they could not synthetically manufacture anything. Many traces of herbs at ancient Roman army bases have been found, as well as medicated wine. An example of these kind of medicine is green jasper, which was used to treat stomach problems. Army doctors had knowledge of the herbs, and perhaps even grew their own in their respective gardens.[29] The Romans were not correct with all of the herbs uses, but a placebo effect possibly still made some of the herbs useful. Pills, also referred to as pastille, consisted of herbs and plants along with a metallic ingredient.

Surgery was not a very common practice during the period of Imperial Rome and was only used as a last option and if absolutely needed. The reason for this was due to the risk of the patient being in more pain post surgery than they were prior to it. Even when performed, it was confined to only surface level procedures, using flax, linen threads, or metal pins. Regarding internal damage that can be caused by diseases, many doctors did not attempt to fix this due to the fear of their medical reputation being damaged if unsuccessful, which was likely to occur due to the lack of knowledge regarding these procedures.
