Evaluating microfossil content of dental calculus from Brazilian sambaquis

To date, limited numbers of dental calculus samples have been analyzed by researchers in diverse parts of the world. The combined analyses of these have provided some general guidelines for the analysis of calculus that is non-destructive to archaeological teeth. There is still a need for a quantitative study of large numbers of calculus samples to establish protocols, assess the level of contamination, evaluate the quantity of microfossils in dental calculus, and to compare analysis results with the literature concerning the biology of calculus formation. We analyzed dental calculus from 53 teeth from four Brazilian sambaquis. Sambaquis are the shell-mounds that were established prehistorically along the Brazilian coast. The analysis of sambaqui dental calculi shows that there are relatively high concentrations of microfossils (phytoliths and starch), mineral fragments, and charcoal in dental calculus. Mineral fragments and charcoal are possibly contaminants. The largest dental calculi have the lowest concentrations of microfossils. Biologically, this is explained by individual variation in calculus formation between people. Importantly, starch is ubiquitous in dental calculus. The starch and phytoliths show that certainly Dioscorea (yam) and Araucaria angustifolia (Paraná pine) were eaten by sambaqui people. Araceae (arum family), Ipomoea batatas (sweet potato) and Zea mays (maize) were probably in their diet.     

Multiple Injury and Health in Past Societies: An Analysis of Concepts and Approaches,and Insights from a Multi‐Period Study

Earlier clinical and bioarchaeological studies found that injury recidivists were most likely to be young adult males. Since then, the clinical meaning of the injury recidivist has expanded to include all individuals with multiple injuries, and other aspects of health have been considered. Our study sought to apply these advances to paleopathology and place multiple injuries in a wider context by investigating: the age and sex distribution of those with single and multiple fractures, and if people with multiple injuries had poorer general health. The sample of 213 males and 190 females (≥18 years old) from six populations in England, Siberia, and Sudan ranged in date from the 3rd century BC to the mid‐19th century AD. Health variables included cribra orbitalia, porotic hyperostosis, periostitis, Schmorl's nodes, enamel hypoplasias, dental caries, and periodontitis. Ante‐mortem injuries were: fractures (0/1/≥2), myositis ossificans, dental trauma, and sharp‐force injuries. The data were analysed using chi‐square and hierarchical loglinear analyses (P = 0.05). No significant three‐way association between age, sex, and injury was found. There was no difference between the sexes when individuals with single versus multiple injuries were compared. There were significant differences in the age‐distribution of people with 0 and 1/≥2 fractures. Males and those 26–35 years old were most likely to have fractures and multiple injuries. Porotic hyperostosis was significantly associated with fractures. There was no significant relationship between general poor health and multiple injuries.

Stress near the start of life? Localised enamel hypoplasia of the primary canine in late prehistoric mainland Southeast Asia

Localised hypoplasia of the primary canine (LHPC) is characterised by roughly circular defective areas of thinned or missing enamel on the labial surface. This defect is rarely reported in bioarchaeological research. Using samples from late prehistoric mainland Southeast Asia, this paper documents the prevalence of LHPC to produce baseline data for this defect. The samples are from seven archaeological sites in Thailand and collectively span from ca. 4000 to 1500 BP. In the combined samples, 32/79 (40.5%) of individuals and 47/199 (23.6%) of teeth had LHPC. The high occurrence of LHPC may suggest there was poor maternal and infant health. There is also a high occurrence of caries associated with LHPC, which has implications for the assessment of deciduous dental health. This paper stresses the importance of the collection of dental enamel defect data from deciduous teeth including LHPC in bioarchaeological research.     

Stable carbon and nitrogen isotopes of human dental calculus: a potentially new non-destructive proxy for paleodietary analysis

Fifty-eight dental calculus samples from medieval and post-medieval skeletons from Vitoria, Spain, and a single sample from an Alaskan Inuit were tested for stable carbon and nitrogen isotope compositions. There was sufficient carbon and nitrogen concentrations to obtain δ¹³C and δ¹⁵N values, and the samples from Spain produced results that were replicable and comparable to European isotope values based on bone collagen collected from literature sources. The Alaskan Inuit calculus sample yielded a δ¹⁵N value of +17.5‰, well beyond the range of the Spanish samples, but consistent with literature data for modern Greenlandic Inuit consuming a diet rich in marine food. There are several potential sources for carbon and nitrogen in calculus. The results of this study yield stable isotope values consistent with those obtained from other biomaterials used as isotope proxies for paleodietary research, including bone collagen, hair, and fingernails, although further work is necessary to verify the fidelity of calculus as an isotope proxy. Many studies in bioarchaeology are precluded by curatorial concerns regarding the destructive analysis of primary biomaterials. However, calculus is an “add-on”, or secondary biomaterial, that is not an integral part of the dental or skeletal system. Hence, its consumption during analysis is technically not destructive. Therefore, isotope analysis of dental calculus may provide a potential new avenue for paleodietary analysis where the use of other primary biomaterials is precluded.     

Molar crown height: not always a reliable method for the evaluation of age-at-death

In this study, we tested the validity of molar crown height, which changes according to the degree of tooth wear, for the evaluation of age-at-death. The sample consisted of 372 first and second molars (lower and upper) from 157 individuals of known sex and age-at-death. For each molar, we measured the height of the two cusps most subjected to wear (protocone and hypocone for the upper M1 and M2; protoconid and hypoconid for the lower M1 and M2). The correlation between crown height and age-at-death was assessed by linear regression analysis. The resulting models were not very robust since a significant correlation was only found for a small part of the sample, at best (maxillary M1) around 35%. The result slightly improved when bucco-lingual diameter (BL diameter), ante-mortem tooth loss and dental caries were considered, mainly for the maxillary M2 for which the model using age-at-death and BL diameter as independent variables explained 47% of the sample (p < 0.001).     

The Ba/Sr ratio,carious lesions,and dental calculus among the population buried in the church La Concepción (Tenerife,Canary Islands)

Certain trace elements may accumulate in bone in relation to dietary habits, so some of them are of interest in paleodietary analysis. This is the case with strontium (Sr) and barium (Ba), whose potential value as paleodietary indicators is enhanced by their relatively inert metabolic behaviour. The presence of carious lesions may indicate consumption of sugar and vegetables, whereas the etiology of dental calculus deposition is multifactorial, although some authors consider this as an indicator of protein consumption. Based on these facts we analysed (1) Ba, Sr, and calcium (Ca) content of inner cortical bone obtained from the ramus mandibularis, by atomic absorption spectrophotometry, (2) presence of teeth with carious lesions, and (3) presence of teeth with calculus deposition in 62 mandibles. All samples were obtained from the church La Concepción, an 18th century burial place in Tenerife. Gender was assessed by analysing genetic expression of amelogenin in some cases (14), and by inspection of pelvic bones when available (41 cases). We found (1) Carious lesions in 32 cases, and dental calculus, in 39; no association was observed between sex and presence of dental caries or calculus deposition, nor between the sex and the proportion of carious teeth nor the proportion of teeth with calculus deposition; (2) people buried near the altar (priests and individuals of the highest social class) showed a significantly higher proportion of teeth with dental calculus deposition (χ² = 5.36, p = 0.021); (3) bone Sr and bone Ba were significantly higher than the values observed in a control group of 10 modern omnivorous individuals; the lowest Sr values were observed among people buried near the altar; and (4) the Ba/Sr ratio was directly related with the proportion of teeth with carious lesions. These data suggest that there were differences in dietary pattern among the individuals belonging to different social classes; overall, consumption of vegetables was widespread, as shown by the high proportion of carious lesions, in relation with raised Ba/Sr ratio, whereas consumption of marine products was scarce.     

Childhood Cranial Trauma from a Late Roman and Merovingian Context from Michelet,Lisieux, France

The Michelet necropolis in Lisieux, France, dating to the late Roman and Merovingian period, comprises of a large number of well‐preserved subadult remains offering a unique opportunity to better understand childhood trauma in the past. The focus of this study was to determine the amount, type and mechanisms of trauma evidenced in subadults from the 4th–8th century AD, and explore potential circumstances surrounding the trauma. The remains of 109 subadults from the Michelet necropolis were examined for the presence of cranial and post‐cranial trauma. Three individuals exhibited perimortem trauma, one individual had an antemortem cranial injury, and no cases of post‐cranial trauma were identified. Cranial trauma affected 4.1% of children with observable cranial remains (N  = 4/97). The children affected were young (2–7 years old), making it unlikely that they would have participated in militaristic activities. Based on the location, morphology and mechanism of injury identified, it is likely that the perimortem injuries sustained by three children were not accidental. The presence of a number of cranial injuries from this site may be related to increased stress in the community related to the decline of the Roman Empire in Gaul, possible raiding barbarian groups during the 4th–5th centuries, or stresses related to the Gallic aristocracy solidifying political powers in northern Gaul during the 5th–7th centuries AD. The consideration and inclusion of childhood trauma in bioarchaeological analyses allows for a more detailed and in‐depth understanding of violence and childhood in the past.

New insights into the consumption of maize and other food plants in the pre-Columbian Caribbean from starch grains trapped in human dental calculus

In a first region wide study, starch grains from human dental calculus from the pre-Columbian insular Caribbean (dating to ca. 350 B.C.–A.D. 1600) are used to identify important plant foods in the diet and to assess potential dietary differences related to age or sex. Results give important insights into pre-Columbian maize (Zea mays) consumption throughout the region, confirming recent studies that indicate that maize was more commonly consumed in the insular Caribbean than originally thought. No age or sex based differences in maize consumption were found. Furthermore, based on the results of new experiments regarding grinding and pressure damage to starch grains, it is clear that maize in the Caribbean was ground, baked and consumed as bread as was the case in large parts of the mainland. Based on our results we tentatively suggest maize consumption in the Caribbean was at least in some cases associated with feasting and ceremonial activities. The variety in other plant foods identified (mostly tuberous root crops) shows that the pre-Columbian inhabitants of the region consumed a broad spectrum, but locally variable diet in which a variety of root crops functioned as staple crops, including marunguey (Zamia sp.) and sweet potato (Ipomoea batatas). We found no indications for the traditionally assumed heavy reliance on manioc (Manihot esculenta) cultivation in the region.     

Dental Pathology,Trauma and Attrition in a Zambian Iron Age Sample: A Macroscopic and Radiographic Investigation

Using morphological and radiographic methods, we analysed the dentitions of 24 individuals from Ingombe Ilede and Isamu Pati Zambian Iron Age archaeological sites. In this study, we determined the frequency and distribution of attrition, pathological conditions and dental trauma. This research also presents the first view of dental health for an Iron Age population in southern Africa. In total, 482 teeth were available for this study with 287 teeth missing, where 50 of these were lost antemortem and one individual had an erupted supernumerary first mandibular incisor. With the use of radiography and morphology, 21.5% (104/482) of the analysed teeth had at least one pathological condition or evidence of dental trauma. Some interesting dental aspects found and discussed in this paper are linear enamel hypoplastic lesions, radicular resorption, periapical lesions, fractures, dental modification and carious lesions. Many of these features were diagnosed with radiography, and this was especially important for those found below the cemento‐enamel junction (p = 0.0202) that are less obvious with macroscopic investigation alone. Additionally, the quantity and direction of dental attrition was studied. There were observed sex differences with the direction of wear, likely representing a sex‐specific cultural practice of using teeth as tools. Overall, the results show that this sample suffered relatively little from dental problems, and many of those observed features were associated with the traumatic procedure of dental modification, whereas others were age and diet‐related. Additionally, with the use of radiography, rare dental fractures and other features were diagnosed; these results demonstrate the requirement for its application in dental studies on archaeological assemblages.

Dental trauma and antemortem tooth loss in prehistoric Canary Islanders: prevalence and contributing factors

Differential diagnosis of the aetiology of antemortem tooth loss (AMTL) may yield important insights regarding patterns of behaviour in prehistoric peoples. Variation in the consistency of food due to its toughness and to food preparation methods is a primary factor in AMTL, with dental wear or caries a significant precipitating factor. Nutritional deficiency diseases, dental ablation for aesthetic or ritual reasons, and traumatic injury may also contribute to the frequency of AMTL. Systematic observations of dental pathology were conducted on crania and mandibles at the Museo Arqueologico de Tenerife. Observations of AMTL revealed elevated frequencies and remarkable aspects of tooth crown evulsion. This report documents a 9.0% overall rate of AMTL among the ancient inhabitants of the island of Tenerife in the Canary Archipelago. Sex‐specific tooth count rates of AMTL are 9.8% for males and 8.1% for females, and maxillary AMTL rates (10.2%) are higher than mandibular tooth loss rates (7.8%) Dental trauma makes a small but noticeable contribution to tooth loss among the Guanches, especially among males. In several cases of tooth crown evulsion, the dental root was retained in the alveolus, without periapical infection, and alveolar bone was in the initial stages of sequestering the dental root. In Tenerife, antemortem loss of maxillary anterior teeth is consistent with two potential causal factors: (a) accidental falls while traversing volcanic terrain; and (b) interpersonal combat, including traditional wrestling, stick‐fighting and ritual combat. Steep‐walled valleys (barrancos) and lava fields (malpaís) required agile locomotion and occasional vaulting with the aid of a wooden staff. Accidental falls involving facial injury may have contributed to AMTL. Traditional conflict resolution involved competitive wrestling (lucha canaria), stick‐fighting (juego del palo), and ritualised contests involving manual combat. These activities made a small but recognisable impact on anterior dental trauma and tooth loss. Inter‐personal behaviours of such intensity leave their mark on skeletal and dental remains, thereby providing insight into the lives and cultural traditions of the ancient Guanches.

An assessment of morphological criteria for discriminating sheep and goat mandibles on a large prehistoric archaeological assemblage (Kerma,Sudan)

This paper presents an assessment of all known dental and mandibular morphological criteria for differentiating sheep (Ovis aries) and goats (Capra hircus) using for the first time an archaeological sample of complete caprine skeletons (90 sheep and 13 goats) from burials at Kerma (Sudan, 3rd and 2nd millennia BC). The species determinations were assessed using cranial and post-cranial morphological criteria. Consequently, the reliability (percentage of correct determination) and efficiency (complementary percentage of intermediate scores i.e. neither sheep nor goat) of 38 individual dental criteria could be fully assessed using a prehistoric homogeneous domesticate population. We demonstrate that, for this sample, individual criteria for lacteal teeth are more reliable for sheep (sheep: 95 ± 3%) than the adult premolars (85 ± 5%) and molars (sheep: 88 ± 2%), whereas for goats premolar criteria were more reliable (83 ± 12%). For efficiency, lacteal dental criteria are better (goat: 97 ± 5%; sheep: 95 ± 3%) than those for premolar (goat: 85 ± 10%; sheep: 79 ± 5%) and molar (goat: 82 ± 6%; sheep: 83 ± 2). We also demonstrated that most isolated teeth can be determined with less than 10% error. However, on average, within specific age classes (0–1 year, 1–4 years and more than 4 years), isolated teeth increased in reliability and decreased in efficiency. The average reliability of the criteria for complete mandibles for each age class for goats and sheep was 100%, when the efficiency was 67, 40 and 50% for goats and over 90% for sheep. This is due to the effect of age on the efficiency of isolated criteria and the poor performance of specific criteria mainly those P3, M1 and M2. We conclude that separate species kill-off profiles are possible. The effect of age on dental criteria would not significantly change the interpretation for specific subsistence strategies focused on one particularly species.     

Dental wash: a problematic method for extracting microfossils from teeth

A variety of microfossils, originating from plant foods, become trapped in the dental calculus matrix. Processing of dental calculus allows extraction of these microfossils. The resulting data can be used to reconstruct diet at the individual and population levels as the identification of microfossils like starch grains and phytoliths to the generic level, and sometimes to the species level, is possible. However, in some archaeological sites, dental calculus deposits do not preserve well enough to be processed. To prevent the loss of information in such cases, we present a technique, called “dental wash”. It permits extracting microfossils from cryptic dental calculus deposits. In the two experimental archaeological cases presented herein we identified phytoliths, starch grains as well as a diatom fragment with this method, whereas in a control sample no microfossils were found. Moderate damage to the teeth was detected when they were already friable due to poor preservation. Minor damage to the surface of well-preserved teeth was observed. This indicates that the proposed method is efficient in recovering microfossils, but unacceptable because of damage to teeth. If the method can be refined, it will expand the potential of dental calculus analysis to a greater range of archeological sites.     

Adding insult to injury: opportunistic treponemal disease in a scalping survivor

Although the taking of scalps is arguably a perimortem trophy‐taking behaviour, cases of scalping survival are occasionally reported in the historical documents of the American Colonial Period and the 19^th century westward expansion. Survival cases are also detected in pre‐Columbian bioarchaeological contexts. Although scalp avulsion injuries can heal without complication, often the process is compromised by secondary osteomyelitis, usually attributable to environmentally ever‐present Staphylococcal or Streptococcal bacteria. A scalping survivor case from the late prehistoric (AD 1200–1600) Hampton site (40RH41) of East Tennessee unusually displays infectious sequelae in the area denuded by scalp avulsion which are pathognomonic for treponemal disease (caries sicca, stellate scarring). This infection is probably a reflection of the easy opportunity afforded by the large size of the wound bed, poor post‐trauma hygiene, and direct inoculation of the diploë by a ubiquitous Treponema.

Reconstructing faunal migrations using intra-tooth sampling and strontium and oxygen isotope analyses: a case study of modern caribou (Rangifer tarandus granti)

Isotopic analyses of incrementally developed dental tissues can be used to reveal patterns of movement and diet in animals. However, the suitability of these methods for the reconstruction of herd movements has not yet been demonstrated. Inter-individual behavioural and isotopic variability at the herd scale, and the implications for archaeological and palaeocological applications, can only be demonstrated through the testing of modern animals. In this pilot study, dual-element isotopic profiles were created from incrementally developed dental tissues of five individuals selected from a modern herd of migratory Alaskan caribou (Rangifer tarandus granti). Enamel from second and third molars from the individuals was sequentially sampled in order to reconstruct time-series isotopic profiles. Variation in the strontium (⁸⁷Sr/⁸⁶Sr) and oxygen (δ¹⁸O_CARB) isotope ratios of sequentially sampled enamel were compared to documented herd movement patterns and local geological and environmental conditions. Four individuals displayed the same general trends, although absolute isotopic values varied. One individual displays a very different trend and may represent a behavioural outlier or an immigrant from a semi-domesticated reindeer herd. The implications of this study to herd movement reconstruction in the past are discussed.     

Trauma in the Crusader period city of Caesarea: a major port in the medieval eastern Mediterranean

Caesarea is the first fortified city to undergo palaeopathological analysis of its Crusader period inhabitants. This study of the 12th and 13th century population aims to determine the major types of trauma present, whether from weapon injuries or accidents. Since the Crusades were known for the significant number of battles and raids that took place, weapon injuries were expected to be common. Thirteen cases of trauma are described and a highly unexpected pattern has come to light. These cases do not include one single example of weapon‐related trauma. Every fracture is of a type expected from accidents or interpersonal violence without weapons. Possible explanations include the location of the city deep within Frankish territory and the robust city walls giving effective protection to the inhabitants, and also that the population were involved in activities that left them prone to accidents but not weapon injuries. The other important finding from this study was that the cases of lower limb long bone spiral fractures had healed in a near‐anatomical alignment. This is not what we would expect, as a proportion of these injuries would normally have been unstable and tend to heal poorly aligned. The good position could have resulted from surgeons' use of splints to immobilise the bones while they healed. This suggestion is supported by laws of the kingdom of Jerusalem, which stated that surgeons were to be punished if they allowed such fractures to heal at an angle.

Efficient but destructive: a test of the dental wash technique using secondary electron microscopy

The Boyadjian et al dental wash technique provides, in certain contexts, the only chance to analyze and quantify the use of plants by past populations and is therefore an important milestone for the reconstruction of paleodiet. With this paper we present recent investigations and results upon the influence of this method on teeth. A series of six teeth from a three thousand years old Brazilian shellmound (Jabuticabeira II) was examined before and after dental wash. The main focus was documenting the alteration of the surfaces and microstructures. The status of all teeth were documented using macrophotography, optical light microscopy, and atmospheric Secondary Electron Microscopy (aSEM) prior and after applying the dental wash technique. The comparison of pictures taken before and after dental wash showed the different degrees of variation and damage done to the teeth but, also, provided additional information about microstructures, which have not been visible before. Consequently we suggest that dental wash should only be carried out, if absolutely necessary, after dental pathology, dental morphology and microwear studies have been accomplished.     

A re-assessment of Basketmaker II cave 7: massacre site or cemetery context

Our ongoing investigation of early maize farming in the American Southwest has entailed stable isotope analysis and accelerator radiocarbon dating of Basketmaker II remains from sites in the Four Corners region. Here we report radiocarbon dates on a large mortuary assemblage excavated by Richard Wetherill in 1893 from a burial cave in southeastern Utah. It has long been thought that all individuals interred in Cave 7 were massacred in a single violent attack given embedded projectiles and evidence for blunt force trauma. However, accelerator radiocarbon dates on purified bone collagen (n = 96) do not lend strong support to this argument, even among the subset of individuals with clear evidence for violent injuries. Moreover, nearly 80% of Cave 7 burials examined in the study show no evidence of perimortem trauma and no adult females or subadults under the age of 12 appear to have suffered violent deaths. Rather than an anomalous single-event massacre, the Cave 7 radiocarbon dataset suggests that raiding and intra-group, male/male violence was episodic among Basketmaker groups in southeastern Utah. Population densities were relatively high and individuals interred in Cave 7 and elsewhere in the region were heavily dependent on maize agriculture, a prehistoric economic strategy typically characterized by high amplitude fluctuations in productivity. Variability in the array of grave goods accompanying Cave 7 male burials and elsewhere suggests competitive social differentiation likely heightened during periods of resource shortfall leading to intra-group conflict, raiding and perhaps ritualized acts of violence.     

Hypodontia of permanent teeth among Middle Palaeolithic hominids: an early case dated to ca. 92 000±5000 years BP at the Qafzeh site

The analysis of the maxillae and mandible belonging to a Middle Palaeolithic child has provided evidence of the early appearance of a developmental dental anomaly among Homo sapiens. The material came from the Near Eastern site of Qafzeh. In the mandible there was agenesis of the left second premolar and congenital absence of the right could not be totally excluded. Additional analyses including two presumed cases of dental development anomalies within contemporaneous prehistoric populations showed that tooth agenesis also can affect the anterior region of the mandible, and could be clearly separated from ante-mortem tooth loss caused by trauma. © 1998 John Wiley & Sons, Ltd.     

Pulp Stones Prevalence in a Historical Sample from Radom,Poland (ad 1791–1811)

This paper provides an investigation of pulp stones in a sample drawn from the historical population of Radom, Poland, dating to between ad 1791 and 1811. This study seeks to determine the frequency of pulp stones, and assess the association between pulp stones and sex, age, dental caries, and dental wear. A total of 780 teeth from 121 adult individuals of both sexes (45 females, 76 males) were examined. Analysis was limited to molars. The average age‐at‐death of each individual was estimated. Total wear scores across the molars were calculated for each individual. Pulp stones were identified by a portable dental X‐ray machine. Pulp stones were found in 94 of 121 individuals and in 273 of 780 molars. No statistically significant correlation was found between pulp stones and age‐at‐death (p  = 0.7625) and sex (p  = 0.0915), but a significant relationship was found between pulp stones and dental wear (p  < 0.0001) and dental caries (p  = 0.0016). Our study found that molars affected by highly advanced dental wear were significantly more often accompanied by pulp stones than molars that had experienced limited wear. Similarly, significant correlations were observed for dental caries. It means that pulp stone formation appears to have been contingent upon the irritation of the tooth crown by factors such as forces acting on the tooth crown leading to dental wear or dental caries.

Weapon‐related Cranial Lesions from Medieval and Renaissance Turin,Italy

Archaeological excavations carried out in the square around the Cathedral of S. Giovanni in Turin brought to light burials referable to the medieval and Renaissance periods. The anthropological examination of the skeletal remains allowed to identify two skeletons from the medieval period (10th–11th centuries) and four skeletons from the Renaissance age (15th century) showing weapon‐related cranial injuries. These peri mortem lesions are indicators of interpersonal aggression and in particular of armed conflicts. The two individuals from the early medieval period presented three traumas consisting in sharp force lesions caused by bladed weapons. As regards the Renaissance sample, the majority of the nine peri mortem injuries were sharp force wounds, followed by a blunt force trauma. These distribution patterns might reflect different fighting techniques, whereas the side distribution and location of the skull trauma provide further indications on the fighting modalities. Identification of the weapons that caused these traumas is suggested. The lack of post‐cranial wounds at Piazza S. Giovanni might be explained by the greater attention paid to the head, which was the main target of attack, or by adequate protection of the body through medieval and Renaissance armours. Otherwise, the wounds in the body would have been found only in the soft tissues, with no involvement of the bones. Despite the presence of weapon injuries, the results obtained from the study of the Renaissance sample are different from the findings of other contemporary battlefields. It is highly likely that the individuals of the Renaissance age were not young soldiers employed in war episodes and brought back for burial in Turin after battles that had taken place elsewhere. Instead, they were probably individuals who had died in riots or in other violent city episodes, as the historical records for the Renaissance age seem to confirm.
