This stone knife from the Rhode Island Historical Society’s collections may have been used to cut animal meat. The knife would have been hafted, or attached, to a wooden handle. Sinew, the ligament that attaches muscle to bone, from an animal like a deer could have been the hafting material that tied the handle to the stone point. Wood and sinew, plant and animal remains, decompose easily over time, especially in Rhode Island’s climate and acidic soils. The stone knife does not decompose and is all that remains of this tool in the archaeological record.
Seasonality and Food in the Narragansett Bay
Essay by Rebecca Marisseau, Ph.D. Candidate in the Department of History at Brown University
What did early Native Americans who lived at Greenwich Cove in Narragansett Bay eat? To find out, archaeologists studied what they call their middens, or trash pits. Archaeologists study ancient middens because they often contain the traces of meals, just like our daily trash. For example, a person might have eaten the meat from an animal but discarded the bones, or they might have eaten the inside of a nut but left behind its shell. Archaeologists can study remains like bones and shells to understand the diets of early people.
At the Greenwich Cove site, archaeologists found seashell middens, which means that early Native Americans ate shellfish from the sea, including quahogs, soft-shelled clams, bay scallops, and mussels. They also found the remains of white-tailed deer and of a bird called a thick-billed murre. Archaeologists discovered some evidence that people ate wild plant foods, including hickory, acorn, and hazelnut. Archaeologists have not uncovered evidence that people at the site ate squash, beans, or corn. The absence of these foods from the material record contradicts the oral history of people who claim descent from the original inhabitants of Narragansett Bay. Descendants assert that corn was a staple of the early Native American diet in this area centuries before European contact. The fact that no archaeological evidence of corn has been found does not mean that the oral tradition is wrong, but it does raise the possibility that there are some missing links in the material record. Evidence of corn may have decayed, or perhaps it exists and has simply not yet been discovered.
Luckily, archaeologists are able to closely examine some of the animal remains to know what time of year people ate them. Archaeologists are interested in this evidence because it can help us know about the mobility, or movement, of ancient peoples. If Native American groups ate food at one place during every season of the year, then it is likely that they lived there all year long, while if there are times of the year when no food was consumed at the site, then the groups might have moved to different places according to the seasons.
How can archaeologists know what time of year something was eaten? Archaeologists must understand the bodies of animals in order to “read” their remains about the time of year of death. Take the quahog, for instance. The shell of the quahog is a useful tool for archaeologists because the shell tells the animal’s life history, including the time of year that it died. As quahogs grow, their shells gain new layers that can be seen under a microscope. In the warmer months, the quahog shell grows fast and forms a large, opaque layer, but in the colder months, the shell grows slow and forms a small, translucent layer. If the last layer on the shell is a small, translucent layer, then the archaeologist knows that the quahog must have died in the colder months, which means that a person harvested and ate it in the winter. Based on quahog shells found at the Greenwich Cove site, we know that Native Americans who lived there between 1000 AD and European contact harvested quahogs in the summer, fall, and winter (the most intense harvest was between October and November), but did not harvest many quahogs in the spring.
Archaeologists can also study deer teeth that they find in middens to learn about when people hunted and ate deer. Similar to quahog shells, deer teeth gain new layers each year, and the type of growth on the outside layer of the tooth tells archaeologists what season it was hunted. Deer teeth found at the Greenwich cove site reveal that the people here had two seasons of deer hunting: one from February to June and the other from October to January.
The study of food remains at Greenwich Cove has changed the way that some archaeologists think about the movement of early Native Americans in Rhode Island. For a long time, archaeologists and historians thought that people did not live year-round on the Rhode Island coast, but rather only lived there in the warm months. This idea came from Roger Williams, who wrote in the 1600s that Native Americans moved away from the coast in the winter, a process he described as the “great remove” in the cold months to the “thick warme vallies.” However, some archaeologists who have studied Greenwich Cove argue that for the last 2000 years of prehistory, earlier Native Americans settled along the coast almost year round. There is evidence to support this argument because archaeologists found food remains there from every season of the year, meaning that people lived and ate in the same place nearly all year long. This is an example of why it is useful to look at more than one source of information while studying the past; sometimes, the material or archaeological record might present a different picture from what is written down. Archaeologists will continue to debate the seasonal mobility of early Native peoples until more evidence comes to light.
Midden: a trash pit
Diet: the kinds of food that are usually eaten by a person or group
Opaque: solid, cannot be seen-through
Translucent: somewhat see-through
Why do archaeologists like to study ancient middens, or trash pits?
What are some of the kinds of foods that the early Native Americans who lived in Narragansett Bay ate?
Why are archaeologists interested in the season when people ate food?
In 1000 years, what do you think archaeologists would discover about you and your family if they studied your trash?
