the Empire became hunting ground for hordes of German tribes: Visigoths
Between the sixth and eighth centuries CE they gave life to an independent kingdom
After their arrival in 568 CE under King Alboin's leadership
they left many traces of their settlement in Northern Italy and their subsequent diffusion towards the south
With historical sources and archaeological data providing a background to our understanding of the Barbarian invasions across Europe
we are confronted with a multitude of information on general cultural phenomena but little evidence on single aspects at a population level
Here we attempt to integrate archaeological
and biomolecular data at the Longobard necropolis of Povegliano Veronese to understand how and to what extent did the Longobard ingression in Italy changed the socio-cultural scenario of the Peninsula
especially considering how central is the role of Italy in the transition between the Roman times and the following post-classical phases
If the decline of the Western Roman Empire represents a strong political and cultural reset
no place like Italy deserves to be investigated in the assessment of how this political shift had an impact on the local population in its interaction with the new “invading” peoples
our understanding of the biological background of local and non-local populations with the transition to the Middle Ages is still lacking
With the two excavation campaigns, an extended necropolis was brought to light, with 164 Longobards burials (Fig. 1).
The location of the Longobard cemetery
The red line represents the ancient Roman road known as Via Postumia
Plan of the cemetery with areas of excavations; burials selected for this study come from highlighted areas
The dashed line represents mean Sr ratio calculated on the faunal samples only
Individuals linked by the dashed line provide both enamel (line) and bone (maker) data
Filled dark shade = early phase; filled light shade = later phases; empty = no chronology
which might have involved some of the animals investigated (see below)
Two further outlying individuals show the highest Sr ratios (0.71073–0.71280) when compared to the other groups
They were coming from localities with largely different 87Sr/86Sr ratio in the labile portion of soil and
The δ18Ow calculated from the human teeth ranges from − 11.6 to 0.6‰
while human bones range from − 8.7‰ to − 4.8‰ with a mean of (− 6.4 ± 1.1)‰ (n = 16)
Mean δ18Ow for the animal teeth is − 7.3‰ (n = 6)
whereas for animal bones mean δ18Ow is − 6.4‰ (n = 8) with values ranging from − 8.6‰ to − 2.7‰
Mean δ18Ow values for both human and animal bones is − 6.4‰
whereas there is a greater gap between the average values of human and animal teeth (− 5.1‰ and − 7.3‰ respectively)
Cluster analysis of human enamel δ18Ow (n = 13) shows three groups, which are presumed proxies of local water sources (Fig. 2SI,a): the first one (9 samples) shows values that range from −7.9‰ to − 4.0‰; the second group (3 samples) ranges between −2.0‰ and + 0.6‰
Only the first group could match ingested water similar to the present-day precipitation
Cluster analysis of human bone shows only two groups (Fig. 2 SI
The first one ranges from − 8.7 to − 6.8‰ and the other from − 6.1 to − 4.8 ‰
Because each isotopic parameter serves as a proxy of distinct geological or environmental contexts
strontium and oxygen data are first discussed separately and further in combination
Wide variation in enamel strontium isotopic composition suggests marked differences in geological background, which probably characterize an area larger than the one investigated (Fig. 2)
individuals either lived in areas with distinct strontium isotope imprinting or ate foods from distinct contexts during enamel formation
Two humans bone signatures have 87Sr/86Sr values
In order to assess a possible relation between origin of the individuals and time of use of the cemetery
we compared strontium ratios with chronological attribution of the burials
The group of “autochthones” includes individuals with both early and late grave goods
The individuals with earlier grave goods (dated to the second half of the 6th century/early decades of the 7th) could represent the Longobards born in the Povegliano Veronese area (unsurprisingly some of them are subadults) or
local non-Longobards who interacted and mingled with the colonizing group
Sr signatures would be consistent with that of the local geology
was the place of settlement of the Longobards during the sixth century CE
hence might represent the place of origin of some of the individuals in the sample
This interpretation is supported by the fact that the group of “allochthones” (with the only exception of T 364) is characterized by early grave goods dated to the first phase of occupation of the cemetery (570–620 CE)
individuals from T 23 and T 426 showed Sr isotopic values of dental enamel that are significantly more radiogenic than those of the rest of the population
Although for only one of the two (T 426) we have a clear chronological attribution (i.e.
we could argue that such individuals were probably coming from a further geological region
which does not correspond either to that of the “autochthones” or to that of the “allochthones”
buried with no grave goods; despite his alien origin
the man must have mixed with the local group some time prior to his death
so as to justify his presence in the cemetery
T 426 is a male died in later adulthood (40–50 years)
found with a funerary assemblage dated to the initial phase of the Longobard settlement in Italy (570–620 AD); like for the allochthones dated to the early phases of occupation
this man suggests an alien provenience although from a more radiogenic geological background
Taking into account the uncertainty on the evaluation of 18δw from 18δph (± 2.5‰) we can state that the variability around the mean of the 18δw values calculated from the 18δph of human bones (Table 3) is small (− 6.4 ± 1.1‰)
the variability is also low for enamel (− 5.8 ± 1.4‰)
the central values for enamels and bones have a high probability to be the same (t-test: psame mean = 0.24; Mann–Whitney: psame mediane = 0.38)
we can state that (a) there is no evidence of variation of isotope features of water ingested by humans found at the site
and that (b) most individuals resided in the same place at least for the final phase of their life (given these are bone values)
if the data are compared with the present-day precipitation (about 7.7‰ ± 2‰ at Verona
a town not far from Povegliano Veronese; Longinelli and Selmo
we can also state that there is no evidence of a significant climatic difference in respect to today
The results also suggest that humans and animals drank from the same water sources
in fact the area is and was characterized by abundant springs
Once again, cluster analysis performed for dental enamel oxygen values appear to differentiate three sub-groups of individuals (Fig. 2 SI
These might be associated with at least three sources of water
which may result from as many geographical areas: the largest group
(n = 9; − 7.9 to − 4.0‰) might come from the Povegliano Veronese area
given that it partially shares mean values associated with the region; a second group
with lighter δ18O (− 1.9 to 0.5‰) could be referred to ingestion of abundant evaporated water
is consistent with a provenance from a colder area; the individual (a non-local for Sr data) is interestingly associated with early Longobard evidence
Whisker and box plot of δ18Oph in dental enamel and bone for Povegliano Veronese humans
some individuals changed the water supply between the first and last phases of their life from higher to lower oxygen values or vice versa
individual T489 has values ranging from − 11.6‰ in enamel to − 7.2‰ in the bone suggesting migration from a colder to a warmer region
The δ18O values for bones do not exhibit variation between the sexes: male data range from − 5.4 to − 7.9‰ with an average of − 6.6‰ while female data range from − 5.3 to − 7.4‰ with an average of − 6.01‰
one Bos and two Sus share the same δ18w found both in human bones and enamel
suggesting that some humans and animals drank from the same water sources
Different values are the most negative δ18w of the Equus and a Bos
drunk from more negative water sources located in a different area
the most positive δ18w of one ovicaprid might be indicative of evaporated water source
The animal bone δ18w are generally more homogeneous
except for the Equus and Bos with the more negative values discussed earlier (respectively with − 8.6 and − 8.5‰)
we could hypothesize an origin at different latitudes from Povegliano Veronese with later movement to the area
The results of this study offer significant contribution
Sr isotope ratios measured for 27 samples from Povegliano Veronese had values (0.70836–0.70906)
which indicate that most of the individuals investigated—either of early or later phases—were likely to be local inhabitants
We are keen to suggest such individuals were “autochthonous” to the region and were likely to drink water mostly from the area of Povegliano Veronese
a region known to have been long occupied by the Longobard people
Most of the individuals in this group are dated to the early phases of occupation of the cemetery
oxygen values indicate that water ingested came from a source that is not in the area of Povegliano Veronese
An extremely small percentage of Sr values (0.71073–0.71280) hint to a migration of “outliers” that includes movement from a broader European region
This hypothesis appears to be confirmed – at least for one individual – by oxygen values
Strontium and oxygen data measured in the skeletal tissues of both animal and humans from Povegliano Veronese unveil pattern of residential mobility of the Longobards in Italy
Integration of isotopic data and archaeological evidence at the cemetery seems to suggest that the first generation of Longobard “colonizers” in Italy have likely merged at an early stage with local inhabitants
the second and following generations of Longobards were native to the region and have acquired foods and water from local environments
across the whole phase of occupation of the cemetery
of alien people either from a wider “Italian” territory or from Central Europe
The results obtained seem to provide evidence of the integration and further “Latinization” of the Longobards in the Mediterranean
which eventually led to the formation of a new Longobard identity in Italy (Rotili
and bone specimens of humans and animals were sampled for strontium isotope ratios (87Sr/86Sr)
whereas teeth and bones of humans and animals were sampled for stable oxygen isotopes analysis δ(18O/16O)
preparation and analysis was performed in accordance with relevant regulations for the treatment of ancient human remains
Permission to analyze the samples was granted by the local SABAP (Soprintendenza Archeologia
Belle Arti e Paesaggio per le province di Verona
and to observe the difference between tooth value and bone value in the same individual
we run two bone analyses for strontium and sixteen analyses for oxygen
In order to define the local range at Povegliano Veronese and to compare the data obtained from teeth and bones of humans and animals, we took soil samples from the burials of area H, namely: T 348, T 426, T 413, T 45 (Table 2)
The burials were selected according to position within the cemetery, dating of grave goods and typology of tomb structure17
we tried to keep a balance in the composition of the sample in accordance to sex and age at death of the individuals
In order to examine strontium and oxygen ratios in humans over time we chose 21 burials dated to phase 1
and 4 burials with undetermined chronology
We further sampled individuals from 3 multiple burials
which despite not providing a date were considered worthy of investigation
After cleaning the surface of each tooth by abrasion with a diamond burr
20–30 mg of enamel powered were extracted and digested in 1 ml concentrated ultrapure HCl
The samples were then evaporated to dryness and redissolved in 2 ml 2 M ultrapure HCl
the samples were mechanically cleaned and authigenic carbonates removed with CH3COONH4 buffer at pH 5 in an ultrasonic bath
Approximately 5 g of cortical bone were reduced to ashes in a furnace at 800 °C for 10 h and then the material was homogenized in an agate mortar and dissolved with 6 N ultrapure HCl
The extracts were processed for Sr isotopic analysis following the procedure of bone analysis
Isotopic analyses were carried out at IGAG-CNR c/o Dipartimento di Scienze della Terra
University of Rome using a FINNIGAN MAT 262RPQ multicollector mass spectrometer with W single filaments in static mode
Sr isotopic fractionations was corrected against 86Sr/88Sr = 0.1194
measured isotopic ratios of NBS 987 Sr standard
resulted as 87Sr/86Sr = 0.710285 ± 10 (2σ; n = 27)
Stable oxygen isotopes δ(18O/16O)ph analyses on the phosphate group of teeth and bones of human and animal bioapatite (ph) were carried out at the Stable Isotope Laboratory of the University of Parma
The sample treatments were the following: samples reacted with 2.5% NaOCl for 24 h to oxidize organic substances; then
the samples were reacted with 0.125 M of NaOH for 48 h to dissolve humic substances
The solutions were then warmed at 70 °C for 3 h and filtered to collect the precipitated crystals of Ag3PO4
The crystals were analyzed by means of TC/EA
thermal conversion-elemental unit on line with a mass spectrometer (IRMS)
According to IUPAC (International Union of Pure and Applied Chemistry)
the isotope ratio 18O/16O is expressed as:
where δ18Osample and δ18OV-SMOV are the isotopic abundances in the sample in analysis and in the reference international standard V-SMOW (Vienna Standard Mean Oceanic Water)
The estimated analytical prediction uncertainty for 18δ is ≤ 0.35‰
In order to relate the values δ18Oph of the \({\mathrm{P}\mathrm{O}}_{4}^{3-}\) anionic group of enamel and bone bioapatite to that
δ18Ow = 1.847 δ18Oph − 0.0384 Iacumin and Venturelli 21
δ18Ow = 1.14 δ18Oph − 0.0274 Delgado Huertas et al.32
δ18Ow = 0.676 δ18Oph − 0.0184 Delgado Huertas et al.33
δ18Ow = 0.990 δ18Oph − 0.0247 Delgado Huertas et al.33
δ18Ow = 1.41 δ18Oph − 0.0318 Delgado Huertas et al.33
δ18Ow = 0.885 δ18Oph − 0.0227 D'Angela and Longinelli34
(It is noteworthy that the equations used for animals could not to be statistically different one from the other)

Fifteen-hundred years ago, a single mighty blow crashed down upon a man in Italy
The wound should have killed him — if not from immediate blood loss
then from an infection for which there were no antibiotics
Maybe it should, said the anthropologists who documented the unusual skeleton's discovery in the newest issue of the Journal of Anthropological Sciences
the blade-armed man lost his hand during a time when an amputation could be a death sentence
His survival well into middle age represents not just a personal triumph
"This [find] shows a remarkable survival after a forelimb amputation during pre-antibiotic era," the team
led by researchers from the University of Rome
"The survival of this [man] testifies to community care
family compassion and a high value given to human life."
The man's skeleton was exhumed about 20 years ago from the Longobard necropolis of Povegliano Veronese near Verona in northern Italy
which dates roughly to between the sixth and eighth centuries A.D.
has so far yielded 164 tombs holding 222 individuals (plus a burial pit containing two greyhound dogs and the aforementioned horse)
their arms all hung straight down at their sides
Further analysis revealed that the man's right hand was missing
that it had been amputated from his forearm by a single blow and that the bones in his arm had ample time to heal before he died (which was likely sometime in his late 40s)
Get the world’s most fascinating discoveries delivered straight to your inbox
In the spot where the man's right hand should be
researchers found a prosthetic limb fashioned from leather straps
which the team dated to the end of the 6th century
Dental analysis showed that one of the man's upper incisors was worn down significantly compared to surrounding teeth
suggesting he had used that tooth for something other than chewing — perhaps for tightening the straps on his prosthetic
How the man lost his hand is another mystery. One big clue: that he even survived a limb amputation before antibiotics existed
"This highlights a community-level effort to provide an ideal setting for healing to take place," the researchers wrote
"This suggests a clean environment and intensive care during the early stages of healing
with the ability to prevent death from blood loss."

The Boerica variety is the only one in the world that can be used for commercialization under the Jingold Bliss brand
"rediscovered" in one of the historic companies controlled by Commercio Frutta: Azienda Agricola Bovo in Povegliano Veronese
Feedback is great thanks to its organoleptic qualities
so other producers can ask Commercio Frutta to join.
"It is a very interesting variety due to its agronomic characteristics and fruit quality
Boerica is currently the only variety that constitutes an improvement of Hayward
our group focused on varietal improvement using Boerica
We are promoting our brand together with our partner (Jingold) so as to increase sales within the top-end green kiwifruit market
This will lead to higher profits thanks to the premium product," explains owner Maurizio Filippi
Commercio Frutta entrusted Consorzio Jingold with the management of the Jingold Bliss brand
which envisages the promotion of a high-quality brand through the Boerica variety
"Commercio Frutta is the facility on a domestic level that deals with the highest quality of Boerica green flesh kiwifruit and our objective is to further increase quantities so as to have even more top-level produce available" explains sales manager Andrea Bini.
"Reaching a considerable critical mass will enable us to tackle markets with a uniform product to provide our producers and whoever wants to join our project with considerable answers."
Commercio Frutta is also investing a lot on a national level on yellow and red flesh varieties such as Jintao and Donghong
which have been doing very well for the past few years
Who is Commercio Frutta?Commercio Frutta was established in September 1993 by two founding partners
the company evolved and widened its range of products with peaches
in order to better support the production chain
the facility merged with another local company and thus extended its production and commercial network
The company has always focused on innovation and on varietal renewal and quality improvement in particular

The great march of the Longobards in our peninsula began in 568 A.D.
when the warriors with long beards began to press impressively at the gates of the Alps to conquer new lands
the burial area of which was subjected to numerous investigations during archaeological excavations carried out between the 1980s and 1990s
the result of a mission coordinated by Mary Anne Tafuri of the Laboratory of Paleoanthropology and Bioarchaeology of Sapienza
has reconstructed the dynamics through which the Longobards arrived in our peninsula after the fall of the Roman Empire and settled on the territory
The study has been published on Scientific Reports Journal
carried out in collaboration with the National Research Council of Italy (CNR)
the University of Parma and the Catholic University of the Sacred Heart of Milan
is based on biomolecular analyses on remains of some of the individuals found in the Longobard necropolis of Povegliano Veronese
Its aim was to investigate the mobility of Germanic populations and the socio-cultural aspects that followed
Mary Anne Tafuri and her team examined the concentration of strontium and oxygen and their stable isotopes (atoms with a variable mass number) inside bones and teeth of a "sample" of 39 buried individuals and 14 animals
selected among the finds that emerged from the necropolis.Oxygen and strontium
have a precise isotopic distribution that can be altered by biochemical and environmental factors
What is interesting is that values related to these alterations are specific of one geographical area rather than another."By detecting these biomolecular data,” says Mary Anne Tafuri
“we were able to highlight the heterogeneity of values within the sample and make a statistical subdivision into three "sub-populations"
distinguished by different geochemical signatures: the natives
those who have spent their whole life in Povegliano Veronese; the allochthonous
who arrived in the area during their life and the outliers
individuals with values outside the variability observed in the first two groups."Subsequently
the researchers investigated the origin and mobility dynamics of that part of the community
who were not born in Povegliano but migrated there during their lifetime
comparing the isotopic data of this group with those of individuals from other Longobard necropolises
The isotopic values of the allochthons of Povegliano were compatible with those of the Longobards buried in the Hungarian necropolis of Szólád
one of the last locations occupied by the Longobards before their arrival in Italy
confirming the reconstruction carried out by the scholars.Moreover
thanks to the data provided by the tomb structures where the individuals were found and the accompanying objects
it has been possible to distinguish between burials attributable to the most ancient phase of the necropolis (late sixth - early seventh century A.D.) and more recent ones (first half of the seventh - first half of the eighth century A.D.)
between individuals belonging to the first and subsequent generations of settlers."We have shown that all the allochthonous individuals found in the burial area of Povegliano Veronese belonged to the first generations,” adds Mary Anne Tafuri
“as they were accompanied by items that can be dated back to the first phase of use of the necropolis
are characterised by later items."The results of the study
which combines archaeological and isotopic data
constitute an important piece in the reconstruction of the dynamics of settlement and mobility of the Longobards as a whole
They also help explain how these warriors integrated into the context of civilisation
capable of combining the Germanic tradition with the classical and Roman-Christian one
