Roman Shipwreck Found Off Coast of Sicily

Archaeologists near the coast of Palermo, Sicily, were able to uncover an ancient roman shipwreck filled with amphorae that dates to the second century B.C.E. (Amphorae are basically jars that were used for transportation of wine and olive oil). The shipwreck in the Mediterranean Sea gave archaeologists more information on the specifics of what was being traded and showed the ship must have been heading to some type of buyer. Being able to look through this wreckage allows archaeologists to know more about the life on board as well as the relationship between coastal populations.(Davis-Marks,1).

In order to learn more about the wreck that was buried deep in the ocean researchers had to use a remote controlled vehicle to capture photos around the wreck.

Finding archaeological sites under water comes with a lot of challenges compared to above ground. For instance, the overall visibility and light conditions is much worse than when digging during the daytime. This also is affected by the actual depth of the site. Along with this, the artifacts are usually buried underneath layers of sediment and trying to remove this is very time consuming and can possible stir up all the sediment which can cause even more problems. In class, we have also talked about how expensive underwater work may be which can be a result of the sheer amount of time going by as well as the equipment needed in order to successfully reveal the artifacts.

Finding all of these vessels shows us how important wine trading was to them.

At that time Sicily’s wine trade was one of the most profitable activities for entrepreneurs. There was even a Sicilian wine named Mamertino that was so popular Julius Caesar wanted it. The discovery of this shipwreck and what archaeologists were able to uncover shows us a period of peace and prosperity in the Mediterranean. Further research is being done in order to find more information about the specific trade routes that were used to transport all of these goods to different countries. Many ancient shipwrecks included items like these and archaeologists usually link these discoveries to wealth. In recent years, other shipwrecks have also been discovered showing similar items and now finding this brings in more information on the trading framework through out the Mediterranean Sea. “The Mediterranean continually gives us precious elements for the reconstruction of our history linked to maritime trade, the types of boats, the transport carried out,’’ said the superintendent of the sea of the Sicilian region, Valeria Li Vigni, who launched the expedition (Tondo,2). Many discoveries like this are being found in similar areas and this has been said to be one of the most significant in recent years.

Obsidian Woven Through Aztec Society

Aztec society is one of the most well known native tribes in the world. They’re most well known for their intricate infrastructure and religion, however they had a very distinct and powerful military as well. The Aztecs heavily relied on warfare to smother invading tribes, gain resources and territory, and collect sacrifices. To gain such power, warriors depended heavily on weaponry such as bows and arrows, spears, javelin, clubs, swords, and specifically, the atlatl. While a fun word to say, it is a deadly weapon when used properly. The atlatl consisted of two separate mechanisms, a javelin or large dart and a wooden hook to sling the projectile to the users target. According to, this weapon was specifically used for long distance and could pierce chainmail armor of European soldiers and leather of other mesoamerican tribes. Almost every warrior in the tribe of city-state had the knowledge of how to wield an atlatl with its obsidian headed projectile. 

Figure 1. a demonstration of how an ancient atlatl would be thrown (Wikipedia 2023)

In their society, it was mandatory for men to participate in warfare, it was viewed as them fulfilling their role as a man and honoring the gods, specifically their war and sun god Huitzilopochtli. Since the Aztecs relied so heavily on warfare and were fearful of the repercussions of having an unworthy sacrifice to their sun god, the Aztecs made a gruesome and morally expensive offering, human sacrifice. 

FIgure 2. An Aztec Sun stone made as an offering to Huitzilopochtli (Aztec Sun Stone, National Museum of Anthropology, Mexico City, 2023)

The reasoning for human sacrifice is circumstantially very sound however. The society feared that Huitzilopochtli would stop the sun, ceasing all life on earth. Typically, Aztecs would turn to prisoners of war as the sacrifice, never encouraging the slaughter of citizens in the city-state. In most cultures of the ancient times, priests would be ranked very high in the hierarchy, but according to, the priests did not have it easy. They were tasked with performing the human sacrifices with obsidian blades. These obsidian blades were made slowly by chipping away shards of the rock into an impossibly sharp edged weapon. The Aztecs used obsidian as projectile points and other tools throughout their community. Creating a knife or javelin head for an atlatl was a very intricate and trying process, one wrong strike to the obsidian and the tool would split in half, ruined. Obsidian was a precious, dangerous, and effective stone. In fact, the stone was so effective in their weaponry that the civilization didn’t even find the need to advance past it and towards metal. 

Figure 3. examples of what obsidian would be shaped into for weaponry (Daily Mail 2012)

Aztec culture and society was very complex and successful, they developed religion, agriculture, warfare and society, with one common thread, obsidian. Its relevance in all aspects of their culture made it a hot commodity and traced throughout Aztec history.

Lithics from Greece contour hominin development throughout time.

Recent class discussions have consisted of explaining the importance and impact of lithics on archeological discoveries. The term lithic is derived from ancient Greek and means rock. This is why lithic technology can be defined as certain techniques that are used to produce various categories of stone tools. The first stone tools from two and a half million years before the present can be characterized as simplistic and non-selective. However, as time progressed significant additions were made to lithics further enhancing hominins’ ability to manipulate these stone tools to their benefit. Early lithics are smaller sections of stone that were produced by striking two stones together. This type of lithic is uniface, meaning that only one side of the stone had been flaked. Whereas the lithics that are more recent are biface tools meaning that two sides have been flaked. The resulting tool has a distinct purpose for each side. In addition, lithics began to be produced with stones of higher quality and structure leading to stronger tools. Furthermore, lithics began to become more symmetrical which shows that hominins underwent adaptations progressively. As time continued to progress lithic technology became even more advanced resulting in different facets of stone stools. Stone tools morphed from uncomplicated scrapers to intricate arrowheads. As hominins progressed, the tools that they used became more complex to keep up with their more elaborate lifestyle. Determining factors of more recent lithics are the bulb point near the bottom of the stone. The bulb point was formed as a result of a stone being struck against another hard surface. These identifiers are crucial in determining the period in which a certain lithic was used. Lastly, these devices molded human advancement and contributed to the development of hominins.

Figure 1. This image is depicting the anatomy of a lithic and providing a variety of views to fully understand how a lithic is developed. (Cambridge University Press & Assessment 2013)

Lithics are being discovered all throughout the world. Recently expert archaeologists: Panagiotis Karkanas, Eleni Panagopoulou, and Katerina Harvati found lithics that are from a “quarter of a million years before present.”(Paphitis 2023) The artifacts were unearthed from a site in the infamous “Megalopolis region of modern Greece.”(Paphitis 2023) These scientists reported that “rough stone tools”(Paphitis 2023) were observed at the site. Since these artifacts were simple stone tools that had sharp flakes it uncovers that they are from the “Lower Paleolithic stone tool industry.”(Paphitis 2023) The tools’ distinct shape and clear edges prove that the tools’ main purpose was for slaughtering and preparation of meals. Also, these tools aided the cultivation process of other plant and animal matter for hominin consumption.

Discovery of 2,000-Year-Old Medical Instruments Uncovers Roman Medical Practices

The constant discovery of past technology undoubtedly changes our perception of how different advancements were made. Although it is true that today’s doctors have developed new techniques and methods, the doctors of the past, specifically Roman doctors, used many of the same medical tools that are currently used. 

Figure 2. A Roman fresco depicting an arrow being removed from Aenea’s thigh. Photograph by  Carole Raddato

In 2022, archaeologists discovered the 2,000-year-old remains of a Roman doctor near Jászberény, Hungary, and alongside the body was a collection of medical instruments including: “a forceps, for pulling teeth; a curet, for mixing, measuring and applying medicaments, and three copper-alloy scalpels fitted with detachable steel blades and inlaid with silver in a Roman style” (Lidz, 2023). People created products with metal alloys because they were discovered to be harder and tougher. Additionally, copper has antimicrobial properties, and in a time where hygiene was not at the same standards as it currently is, it was important to limit the chance of infection as much as possible. However, the tools were probably made without this intention. Egyptians first mentioned the use of antimicrobial effects, and they used it to sanitize drinking water and to treat chest wounds. 

Figure 1. Copper alloy medical instruments that were uncovered at the site in Hungary. Photograph by Rusznák Gábor/ELTE

The detail and material of these instruments indicated that the doctor was high-ranking and traveled to this area to perform his duties. Jászberény was part of a region outside of the Roman Empire and had a lot of conflicts. It was odd that a well-equipped medical professional would be there unless they came to the aid of a prestigious figure. Doctors were very rare according to Dr. Samu, research fellow at ELTE and member of the team on the dig, as, “Studying medicine was only possible, at the time, in a large urban center of the empire” (Lidz, 2023). Limiting the practice to a certain part of the empire, made medical work a very important occupation. Although this was not the first medical kit to be discovered, it was a rare find. Also, the limited amount of education offered, created many inexperienced medical professionals. Building a reputation in the empire would be important, indicating why this body that was discovered had such well-made instruments. Firsthand medical experience could also be found on the battlefield adding another possibility as to why the body could be found in this region.

The grave was purposefully chosen, and the doctor was most likely buried with his instruments as a sign of respect. However, as with all discoveries, it is not the only possibility and others must be considered.

The Role of Animal Tool Use in Understanding Human Cognitive Development

Recent discoveries of stone flakes from Macaque monkeys are challenging previously made assumptions of human cognitive evolution and abilities (Greenfieldboyce 2023). The earliest stone tools were quite simple – using direct percussion, one would use a hammer stone to break off flakes of another stone, called the core, to create a tool. In the first stages of this development, tool-making often only meant breaking a stone in half to create a sharp edge, but this developed into more refined tools, created by carefully flaking off stone, eventually on both sides of the tool (Renfrew 2018, 212).

An example of the earliest examples of stone tools – often simply sharp rock edges or flakes (Renfrew 2018).

An important part of the daily life of the Macaque monkeys in Thailand is the consumption of oil palm nuts. To eat the nuts, Macaques place the nut on a flat stone and then hit it with another stone, cracking it open. When the monkeys miss the nut, which can happen often, they may unintentionally break the flat stone underneath the nut, creating stone flakes that are very similar to early stone tools (Zorich 2023).

A Macaque monkey sits holding the stone tools used to crack a nut, surrounded by stone flakes (CGTN 2018).

Despite the fact that these flakes are largely understood to be unintentional and not used, there are a few possible implications of this discovery. The first is that early humans could have been inspired by the flakes they saw macaques making, leading them to create the first intentional stone flakes. Recent research has suggested that the date of development for stone tools may be over 3 million years ago rather than the previously imagined 2.6 million years ago. The discovery of these artifacts provides concrete evidence for an earlier date of the development of stone tools (Proffitt 2023).

The discovery of the Macaque stone flakes is also significant as it calls into the question the validity of flakes previously identified as anthropogenic. The stone flakes that the Macaques produce are almost indistinguishable from those intentionally created by humans. According to a study by Tomos Proffitt, around 20-30% of the earliest flakes could be attributed to the Macaques (2023). However, it is still possible to distinguish the two. Because the Macaque flakes were produced unintentionally and not used as tools, they lack the distinctive use-wear patterns that early human stone tools. In addition, if an archeologist has access to the core stone that the tools were flaked off of, they can analyze percussive patterns to determine if the entity creating the flakes had knowledge of fracture patterns and was using those patterns intentionally (Greenfieldboyce 2023). 

Because both types of flakes are so similar, this discovery emphasizes the importance of an accurate behavioral interpretation of artifacts. Upon first glance, Macaque flakes can easily be confused with human’s intentional flakes. Only with careful observation and analysis can the two be identified as separate entities. However, the striking similarities between the two types of flakes provides important evidence for an earlier development date of stone tools used by humans, potentially altering our understanding of the evolution of human cognitive ability.

Grief may be universal

The practice of burying the dead is a deeply rooted human, or so we thought, tradition that most likely began even before written history. It is not only a ritual to bring peace for the deceased, but can also reflect on the cultural and spiritual beliefs of a group. Turns out this is not only a human ritual, but non-human animal species have also been found to bury their dead. The homo naledi are a primate species that was discovered by Lee Berger at Stony Brook University (Romey). The homo naledi are scarily similar to the homo sapien on a physical level including similar: teeth, jaws and feet (Johanson). Thousands of their bone fragments were found in a deep underground chamber dubbed “the Chute”, located within the Rising Star cave system in South Africa’s Transvaal region (Romey). Although the name suggests that the bodies were dropped down “the Chute”, the condition of the skeletal remains alludes to the idea that the bodies were individually placed, like in graves for modern burials. The researchers who first found these remains said they were “found so deep within the cave system that they must have been intentionally put there by other members of the species (Davis)”. This burial is said to have occurred about 300,000 years ago, making it one of the oldest burials that we know of thus far. The arrangement of bodies within this complicated terrain hint at a symbolic or ritualistic significance. A study was conducted to see if primates were able to conduct rituals and it was found they only met certain qualifications, so it was called proto-rituals (Tennie & Schaik). For humans, to be considered a ritual, the action must be symbolic by nature and must be copied. The definition is similar for primates, which must follow the following criteria: “socially shared, symbolic feature(s) that are created via actions and/or results that require copying” (Tennie & Schaik). Some researchers argue that this presumed burial site reflect the homo naledi’s beliefs in an afterlife or their desire to commemorate the deceased. Others suggest that they may have been a way to strengthen social bonds within the group to express grief or loss. The practice of burying the dead has persisted across hundreds of thousands of years and continues to be a central aspect of human cultures worldwide. While modern burial practices may vary slightly from those of early homo species, the underlying principles of respect for the deceased and the need to commemorate their lives, as well as their ancestral past, remain consistent.

The Importance of Pre and Post Colonial Sources in Mesoamerican Cognitive Archeology

Discovering how people once thought is vital in contextualizing the events which unfolded in the past. Learning the rhetoric and philosophies of past people can inform the motivations and ideology which may have contributed to the manner in which events occurred. At a glance, this issue may look like it should be left entirely to historians as thoughts seem to leave no trace in the archeological record. Afterall, you can not dig a 50 centimeter by 50 centimeter sampling hole and find a thought floating around in there.

 What an archeologist can uncover in a sampling hole are symbols (which are pretty darn close to thoughts). A symbol is an object, Item, or idea which represents something else. An archeologist in the Yucatan peninsula might uncover a “yellow glyph” and identify it as the Maya symbol for south. (Miller and Taub 65-67) All human cultures are full of symbols, and very few if any are universal to all cultures. Mesoamerican religions offer strong depictions of serpents as revered gods (Miller and Taub 149) whereas Abrahamic religions are more likely to associate snakes with feared “devil.” It is the job of the archeologist to look past their own cultural symbols in order to decipher past ones.

These Symbols represent different directions. (Miller and Taub, 67)

During the conquest of the Americas, many Spaniards lacked the moral relativism to appreciate the culture of Indigenous Mesoamericans. Mesoamerican texts were labeled as idolatry and were burned. Information regarding thousands of years of recorded religion, culture, and ideology were engulfed by flames. Only fifteen pre-contact Mesoamerican books survived the conquest (Turner, 4). Despite this scarcity caused by Colonial atrocities, much can still be learned from these pre Colonial sources.

A wonderful example of this is the oldest surviving book in the Americas, the Códice Maya de México. Dated to 1051-1154, this document measures the movement of the planet Venus, revealing information about Mayan astronomy and mathematics through the way in which they were able to measure planetary movements. These movements are also contextualized within Mayan religiosity. 

On page 7 of the codex Venus’s 8 day period of disappearance is represented by Mayan numeral 8 () on the top left corner of the codex (also a symbol!). It is thought that Venus enters a “supernatural realm of jade and sunlight” depicted by a lance holding deity beside a “tree whose branches produce precious round jewels” Venus then returns on page 8 as the morning star (Turner, 76). Although the Mayans had a different writing system, a base 20 counting system, and a pantheon of unique deities. It is still possible to understand their symbols and the roles they played within their society. This example regarding pages 7-8 of the codex is only a sample of what we can learn from pre Hispanic books. 

Page 7 of the Codice Maya De Mexico (Formerly known as the Grolier Codex)

While much can be deciphered from the few remaining pre Colonial books, Archeologists and historians also rely heavily on post contact sources while still thinking critically about the biases held by their authors. Bernal Diaz Del Castillo’s Narrative, for example, can tell us much about Aztec foreign relations with neighboring groups. Besides travelogues, ethnographic sources were also made. Book 10 of the Florentine codex by Fray Bernadino de Sahagun has a list of Aztec Tlatoani and the townships conquered during the reign of each of them. Book six of Sahagun’s codex revolves entirely around Aztec rhetoric and moral philosophy making it extremely useful in understanding Mesoamerican thought. Archeologists must combine knowledge from both types of sources in order to get a clearer image of the past.

Florentine Codex - Wikipedia
A page from the Florentine Codex with images and Nahuatl writing.

Today, the internet presents exciting new opportunities for Mesoamerican cognitive archeology. The Getty Museum is set to launch the Digital Florentine Codex, an innovative and intuitive new way to study that source. The codex will include searchable terms, glossaries, lesson plans, and references to other sources including pre Hispanic ones. By combining pre contact and post contact sources, Mesoamerican thought can be better understood, allowing archaeologists to discover the hidden meaning among symbols lying between the stratigraphic layers of Mexico and Central America. By unearthing lost cognition and increasing its accessibility we can begin to counteract the cultural genocide perpetrated by Spanish colonization.

Recent Findings Date Earliest Stone Tools at 3.3 Million Years Ago

Recent findings in the Lake Turkana region of Kenya date the oldest stone tools back thousands of years earlier than what was originally thought. The oldest stone tools were previously thought to be made by human ancestor Homo habilis (Figure 1) 2.8 million years ago in modern-day Ethiopia. However, these new stone tools push that date back to 3.3 million years, and were not even made by a direct human ancestor (Figure 1).  

Figure 1: Differences in the parts of the skull (crania, maxillae, and mandibles) of Australopithecus africanus, Paranthropus boisei, and Homo habilis.

The tools were found alongside the teeth of Paranthropus boisei (Figure 1), a type of hominin, and co-existed with many human ancestors like the Homo habilis. The teeth being found with the tools could indicate that Paranthropus used these stone tools. Thirty of these stone tools were found at the Lomekwi 3 site of many fossilized animal remains, those remains showing signs of butchery. The animals at the site included ancient hippopotamus, antelope, and baboon. These stone tools included hammerstones, cores, and flakes, all tools used to skin or pound animals and animal meat. The use of stone tools opens up a lot of new food options in the competitive environment. Especially with the tough, leathery skin of a hippo, stone tools would be very beneficial to getting into the meat. Most likely, the Paranthropus found a hippo carcass and cut off the meat they needed, as there were not any stones used for weaponry at the site (Figure 2). 

Partially excavated bones and associated artefacts.

Different methods of dating were used to confirm the date of the tools, such as radioactive dating and geomagnetic reversal dating. Radioactive dating is a method of dating rocks and other minerals by tracking specific radioactive isotopes like uranium or argon. By determining the rate of decay of the isotope, a relative date of the tool in question can be gathered. Geomagnetic reversal dating works by tracking the number of complete reversals in the Earth’s magnetic field, specifically in the poles. These dating methods, together with site analysis, proved that these stone tools were around 3.3 million years old. However, experts question if Paranthropus even made the tools. Some scientists believe that there was no way for the Paranthropus to have used stone tools, as they have teeth that indicate a more vegetarian diet, negating the need for meat-cutting tools. Even if Paranthropus didn’t construct the tools, the earlier date of use is still quite significant. 

However, if Paranthropus boisei did make the tools, it shows a type of convergent adaptation, in that different lineages saw the need for the same type of object. It also goes against the idea that the modern human lineage was the only one capable of tool making for a specific purpose. Humans may not be the only ones capable of this sophisticated tool usage, other organisms can develop it as well, which is a notable development.

The Crucial Role of Teeth in the Understanding of Ancient People and Bioarcheology

The field of Bioarcheology involves the study of skeletal remains of humans, specifically those found at archaeological sites. The study of these remains gives unparalleled insight into the many facets of ancient civilization, especially in relation to diet and environment. One of the most important subfields of Bioarcheology is dental anthropology (Hillson 2014). The study of one’s teeth is among the best ways of extracting information regarding both the individual who the tooth belongs to, as well as that individual’s environment and culture.  

Due to tooth enamel being the hardest tissue in the body, being 96% dense inorganic hydroxyapatite, it tends to preserve very well regardless of environmental factors (ADA 2022). In fact, a 1.8-million-year-old human tooth was found in 2022 in the nation of Georgia (Reed 2022).  

1.8 million year old tooth found in Georgia

Through a multitude of tests that can be run on the tooth, like carbon dating, archaeologists can put together a somewhat detailed picture of what that individual’s life was like. From lab tests using carbon and nitrogen isotopes in the enamel, scientists can understand and reconstruct diet and where food sources were originally from (Mayne 2015). This could be pivotal in establishing whether one was a part of a nomadic hunter gathering society or if they relied on agriculture for sustenance. Other testing can even give insight into the last 20 years of that individual’s life, which can be pivotal in tracking the progression of a person’s life. This is something that is otherwise incredibly difficult to learn from any other finds at a site (Mayne 2015). Scientists can also extract the exact age of the individual when they died using isotopic dating (Mayne 2015).  

The enamel is the outer most layer of the tooth and where isotopes are extracted from.

Other than using chemical testing, information can also be extracted purely through observation of the tooth. People of Hunter Gatherer societies typically had overbites, causing a specific grinding of the tooth to become common (ADA 2022). People of agriculture-based societies typically show increased pitting, small holes on the front of the tooth, due to the more common reliance on wheat and other carbs (ADA 2022). This also will lead to the increased development of cavities (ADA 2022). 

Without the analyzation of teeth, scientists’ understanding of ancient people would be far more limited. They provide unparalleled insight into the past, giving data that not only leads to explanations of the person who the tooth belonged to, but also of that person’s environment and culture.

Strontium Isotope Analysis in Hungary

Isotopes are atoms of a certain element that have the same number of protons but a different number of neutrons, resulting in different masses. Isotopic analysis is the practice in which isotopes are separated and studied on the basis of their differences in mass. This study is conducted through the use of mass spectrometry (Bronk, McCarthy 2008). Because unstable isotopes tend to degrade over time, stable isotopes are favored in isotope analysis. This is valuable to archaeologists because they can use it to study the movement of populations, diets, and past environments through ancient human remains (Blakemore 2019).

Strontium is a popular subject for isotopic analysis in archaeology because it can determine “residential origins and migration patterns of ancestral humans” and is incorporated into the human body through diets (Dvoracek). Strontium isotopes can be obtained through tooth enamel and bones. The study of these isotopes is shown to be able to identify “more subtle shifts in prehistoric human mobility” (Giblin 2008). The analysis of strontium isotopes was employed on the Great Hungarian Plain, Alföld, to study the time period from the end of the Neolithic to the Copper Age. For this, Sr-86 and Sr-87 were analyzed. Before the application of strontium isotope analysis, archaeologists had reason to believe that there was a change in interaction between the people and the environment. For example, there is evidence that societies became increasingly more mobile, which could have been due to a transition to becoming an agro-pastoral economy, one in which “social organization [is] based on the growing of crops and the raising on livestock as the primary means of economic activity” (Giblin 2008; Hakansson, 1998).

The results of the strontium-isotope study in Hungary show that there was a big change in how societies interacted with the environment between the Neolithic Age and the Copper Age. The individuals from the late Neolithic population were proven to have less variability in their strontium isotopes compared to the Copper Age population, who had more variation (Giblin 2008). Archaeologists believe that this dramatic change in strontium presence can be attributed to a transformation in ways of life. In the late Neolithic period, settlements were large and  concentrated; contrastingly, Copper Age settlements were smaller and spread out over a greater distance. The change in social structures is consequently believed to have changed the mobility of societies, which further changed methods of agriculture and obtaining sustenance (Giblin 2008).

In the late Neolithic period, there was a dramatic increase in large game hunting and the consumption of cattle. In the Copper Age, hunting became less popular as there was a shift to a more systematic way of raising stock such as pigs, sheep, and goats. After the analysis of pig strontium isotopes, it has been determined that they have a wider range of values. The increased consumption of pigs in the Copper Age population’s diet would contribute to their higher level of strontium-isotope variability (Giblin 2008).
