Archaeology versus written records, and the limits of each

The human past is immense. It stretches back hundreds of thousands of years, to the very first tool-making humans. Trying to understand such a long time, and the many different ways people have lived, is a huge task. To do this, we need to gather information, or *evidence*, from the past. Just as a detective collects clues to solve a mystery, historians and archaeologists collect evidence to understand what happened and why. There are two main kinds of evidence we use to learn about the past: archaeological evidence and written records. These two ways of understanding the past are like two different windows looking into the same room. Each window shows something unique, and each has a frame that might block part of the view. To get the fullest picture, we need to look through both. Let's start with *archaeology*. Archaeology is the study of human history and prehistory by looking at things people left behind in the ground. When archaeologists study the past, they are looking for physical things. These physical things are called *artifacts*. An artifact is any object made or used by humans. This could be a stone tool, a piece of pottery, a carved statue, or even a tiny bead. Archaeologists also study *features*. Features are things made or changed by humans that cannot be easily moved, like a hearth (a fireplace), a wall, a ditch, or a burial site. They also study *sites*, which are places where people lived, worked, or performed ceremonies, like an ancient village or a temple. The job of an archaeologist is not just to find these things, but to carefully dig them up, a process called *excavation*, and record exactly where they were found. This is very important because the *context* – where an artifact is found in relation to other artifacts and features – tells us a lot about its meaning and use. For example, finding a cooking pot near a hearth tells us more than just finding a pot by itself. One important early archaeologist was Augustus Pitt Rivers, who worked in the late 1800s. He believed in digging very slowly and carefully, recording everything, even the small, seemingly unimportant things. This careful method helped change archaeology from just treasure hunting into a scientific study. Later, William Flinders Petrie, working in Egypt around the same time, developed a method called *seriation*, which allowed archaeologists to put artifacts in a chronological order (from oldest to newest) even without written dates, just by looking at how their styles changed over time. Archaeology is incredibly important because it can tell us about times and places where people did not write. For example, the very first humans lived hundreds of thousands of years ago, but writing only appeared much, much later. The period *before* writing is called *prehistory*. For all of prehistory, archaeology is our only way to know how people lived. Even after writing began in some parts of the world, many societies continued to not use writing, or used it only for very limited purposes. Archaeology gives a voice to these groups. It also shows us how ordinary people lived, not just kings or priests. However, archaeology has important limitations. One major limitation is *material bias*. This means that archaeology primarily finds things that are durable – things that last a long time. Stone tools and pottery survive well in the ground because they do not rot. But what about things made of wood, cloth, leather, or food? These organic materials decay and disappear over time, especially in most climates. This means that many aspects of daily life, like what clothes people wore, what they ate, or how their houses were furnished, might be lost to us. We might find a stone knife, but not the wooden handle it once had, or the animal it was used to butcher. So, the picture we get from archaeology can be incomplete because so much of what people used simply vanishes. Another challenge is *interpretation*. When archaeologists find an artifact, they have to figure out what it was for. Sometimes it's easy: a sharp piece of flint is clearly a cutting tool. But what about a small, finely carved object with no obvious use? Was it a toy? A religious item? A personal ornament? Archaeologists must infer its function, which means they must make educated guesses based on similar objects found elsewhere, or by understanding the culture it came from. This inference is not always certain. We can see what people *did* with objects, but not always what they *thought* about them. This leads to another limit: archaeology struggles to reveal *ideas and beliefs* directly. We might find evidence of rituals, like special burial practices or temple structures. But what did the people *believe* about death or their gods? What were their complex stories or philosophies? These abstract ideas are very difficult to recover from physical remains alone. Archaeology can show us that people buried their dead with offerings, but it cannot tell us their prayers or their hopes for an afterlife. It shows us evidence of a powerful ruler, but not the specific laws or political ideas that shaped their rule. Finally, archaeological excavation is by its nature *destructive*. When archaeologists dig up a site, they are removing things from their original place. Once a site is dug, it cannot be put back exactly as it was. This means that careful recording of everything found, and its exact location, is absolutely vital. If an archaeologist is not careful, they might destroy valuable information forever. This is why famous archaeologists like Mortimer Wheeler, working in the mid-20th century, stressed very systematic and scientific excavation methods, using grids and careful layers to understand the site's structure. Now let's turn to *written records*. Written records are documents, inscriptions, or any other kind of text that conveys information using symbols. They are direct messages from the past. The earliest known writing systems appeared around 3400-3300 BCE in Mesopotamia, a region in what is now Iraq. This is an important date because it roughly marks the start of *history* in those places – the period for which we have written records. Before this, as we said, was prehistory. Written records can give us incredible detail that archaeology cannot. They can tell us names of kings, specific laws, stories, poems, economic transactions, letters between people, and even personal thoughts. For example, we might find a legal text from ancient Mesopotamia called the Code of Hammurabi, written around 1754 BCE. This long stone pillar, or *stele*, records over 280 laws. It tells us about crimes, punishments, family life, and prices. This is information archaeology alone could never provide. Another example is the ancient Greek historian Herodotus, who wrote his "Histories" in the 5th century BCE. He traveled widely and recorded the customs of different peoples, their wars, and their beliefs, giving us a rich narrative of his world. However, written records also have significant limitations. One of the biggest is *survival bias*. Just like organic artifacts, many ancient texts have simply been lost. They might have been written on papyrus (an ancient paper-like material) or parchment (animal skin), which can decay. Fires, floods, and wars have destroyed countless libraries and archives. We only have a small fraction of all the writing that was ever created. The texts that *do* survive might not be representative of all the texts that once existed. We might have many religious texts, but few everyday shopping lists, simply because religious texts were copied and preserved more carefully. Another crucial limitation is *literacy rates*. In most ancient societies, only a small number of people could read and write. These were often elite groups: scribes (professional writers), priests, government officials, or wealthy merchants. This means that most written records reflect the perspectives, interests, and biases of these elite groups. The voices of ordinary farmers, laborers, or enslaved people are often absent, or only mentioned in ways that reflect the elite's view of them. So, written records might give us a very biased picture of society, focusing only on the top levels. This is sometimes called the "tyranny of the text," where we let written records dominate our understanding and perhaps overlook what life was like for the vast majority of people. Related to this is *intentional bias*. Authors often had specific reasons for writing what they did. A king might commission a text to praise himself and make his enemies look bad. A religious text might be written to promote certain beliefs. A legal text might be designed to maintain social order in a particular way. This means that written records can contain propaganda, self-promotion, or deliberate misrepresentation. Historians must always ask: "Who wrote this? Why did they write it? Who was their audience?" For example, when reading an ancient king's boastful account of his victories, we should remember that he wants to appear strong and powerful, and might exaggerate his successes or minimize his failures. Then there are *language barriers and decipherment*. To read ancient texts, we must understand the language they are written in. Sometimes these languages are no longer spoken. For example, ancient Egyptian hieroglyphs were a mystery for centuries until Jean-François Champollion deciphered them in the early 1800s, using the Rosetta Stone which had the same text written in three different scripts. Similarly, Henry Rawlinson was key to deciphering ancient Persian cuneiform in the mid-1800s. Even when a language is deciphered, its nuances, jokes, or cultural references might still be difficult for modern people to fully understand. Finally, there is a major *geographical bias*. Writing systems developed in specific parts of the world, like Mesopotamia, Egypt, China, and Mesoamerica. Many other cultures, throughout history, never developed writing. This means that for vast regions of the world – for example, much of Africa, North and South America before European contact, or the Pacific Islands – written records simply do not exist for most of their past. For these areas, archaeology is almost our sole source of information. When we combine archaeological evidence and written records, we often get a much richer and more complete understanding of the past. They can confirm each other, or sometimes, they can seem to contradict each other. When they contradict, it forces historians and archaeologists to dig deeper, to re-examine their evidence, and to consider new explanations. For example, written texts might describe a grand city with many temples and palaces. Archaeology can then uncover the physical remains of that city, showing us its layout, its size, and the actual materials used to build those structures. Conversely, archaeology might uncover evidence of a widespread trade network, indicated by foreign artifacts found in many different places. Written records might then tell us the names of the merchants, the goods they traded, and the prices they paid, adding specific details to the archaeological pattern. Sometimes, archaeology can fill in the "silences" of written records. If written texts only talk about kings and nobles, archaeology might reveal the modest homes of ordinary people, their tools, and their food, showing us that their lives were very different from the elite descriptions. For instance, Roman written sources often describe the grandeur of Rome, but archaeological excavations show the everyday lives of city dwellers, the kinds of food they ate, and their simple homes, which were often not as grand as the writers suggested. However, historians constantly debate how to balance these two types of evidence. What if a written text claims a great battle took place at a certain location, but archaeology shows no evidence of such a battle there? Do we trust the text or the dirt? Usually, historians try to find ways to reconcile the evidence, perhaps by questioning the text's accuracy or by looking for very subtle archaeological clues. They know that both types of evidence are not completely "objective." Human choices were involved in creating a written text, and human choices are involved in deciding what to dig and how to interpret artifacts. By carefully using both archaeology and written records, understanding their strengths and weaknesses, we can piece together a more nuanced and detailed picture of the human past. We can see both the broad strokes of how societies were organized and the tiny details of everyday life. We can hear the voices of the powerful, and infer the experiences of those who left no words. This combination is essential for truly understanding the rich and complex story of humanity. In our next lesson, we will explore another crucial aspect of understanding the past: how we figure out *when* things happened. We will look at methods like stratigraphy and radiocarbon dating, which allow us to place archaeological finds and historical events in their correct order and time.
