An artifact (spelled artefact in British English) is any object made, shaped, or modified by human beings. In the field of archaeology, an artifact is a physical item recovered during excavations that gives clues about past societies.

Artifacts include everyday tools, pottery, weapons, jewelry, clothing, and works of art. By studying these objects, scientists can learn how ancient people lived, what they ate, and how their cultures developed.

Artifacts form a core part of what archaeologists call material culture. This term refers to all the physical things created by a society that survive long after the people who made them are gone.

Understanding Artifacts in Archaeology

Archaeologists study human history by uncovering physical objects left behind over thousands or even millions of years. Every artifact serves as a piece in a gigantic historical puzzle.

What Counts as an Artifact?

To be called an artifact, an object must show evidence of human activity. This can range from a finely carved gemstone to a simple broken rock used to cut meat.

Stone tools: Arrowheads, scrapers, and hand axes made by chipping flint or obsidian.
Ceramics: Clay pots, cooking dishes, cups, and decorative tiles.
Metalwork: Bronze swords, iron farming tools, copper coins, and gold ornaments.
Organic items: Woven baskets, leather shoes, carved bone combs, and wooden handles.
Art and ornaments: Amulets, beads, statuettes, and wall carvings.

Artifacts Compared to Ecofacts and Features

When archaeologists dig at a site, they find several types of ancient material. They carefully divide these finds into three main categories:

Artifacts

Artifacts are portable objects that people made or changed. If someone picked up a piece of wood and carved it into a spoon, it became an artifact.

Ecofacts

Ecofacts (also called biofacts) are natural objects found at a site that humans used but did not artificially shape. Examples include animal bones left over from dinner, ancient seeds, pollen grains, and plant husks. Ecofacts tell researchers what crops ancient people grew and what wild animals lived nearby.

Features

Features are human-made structures that cannot be moved without destroying them. Examples include fire pits (hearths), storage pits, brick walls, roads, and trenches.

Manuports

A manuport is a natural object moved by humans to a new place without being modified. For example, if an ancient hunter carried a smooth river pebble many miles away to use as a hammer, that stone is a manuport.

Geofacts

A geofact is a naturally broken rock that looks like a human tool but was actually shaped by natural forces, such as river currents or falling boulders. Archaeologists study microscopic wear patterns on stone edges to tell real tools apart from geofacts.

The Life Cycle and Context of Artifacts

Every artifact goes through distinct stages before an archaeologist discovers it. Understanding this journey helps researchers interpret what the object meant to its original owners.

Behavioral Processes

The behavioral process includes every step of an object's active life:

Acquisition: Gathering raw materials, such as digging clay from a riverbank or mining copper ore.
Manufacture: Shaping and firing the clay, or smelting and casting the metal into an item.
Use: Using the object for cooking, hunting, trading, or ceremonies.
Deposition: Losing, discarding, or burying the object when it broke, wore out, or served its purpose.

Transformational Processes

After an object is buried or abandoned, nature and later humans can change it:

Natural decay: Wood rots, iron rusts, and cloth dissolves in wet soil.
Geological movement: Earthquakes, floods, and shifting soil can move items or crush delicate ceramics.
Human disturbance: Later builders might dig foundations through older layers, moving artifacts out of place.

Why Archaeological Context Matters

Context refers to the exact location of an artifact and its relationship to other objects around it. A rare coin loses much of its historical value if nobody knows where it was found.

Primary Context

An artifact is in its primary context if it remains undisturbed in the exact spot where ancient people left it. For example, a set of dishes sitting on a kitchen table inside a home buried by volcanic ash is in primary context.

Secondary Context

An artifact is in secondary context if natural forces or human activity moved it from its original spot. For example, if a river swept away an ancient campsite and deposited stone tools downstream, those tools are in secondary context.

Matrix and Provenience

Matrix: The physical material surrounding an artifact, such as sand, clay, volcanic ash, or gravel.
Provenience: The exact three-dimensional spot (latitude, longitude, and depth) where an item is found.
Provenance: The documented historical record of who owned an artifact from discovery to its current location.

How Scientists Analyze and Date Artifacts

Once artifacts are carefully uncovered and cataloged, scientists use modern laboratory methods to study them.

Typology and Classification

Archaeologists group artifacts into categories based on shape, material, and decoration. This practice is called typology.

By comparing styles, researchers can see how designs changed over generations. For example, pottery shapes often evolved rapidly, allowing experts to determine the era of a newly found pot simply by looking at its rim or handle shape.

Scientific Dating Techniques

Determining the exact age of an artifact is essential for building a reliable timeline:

Stratigraphy: Archaeologists study soil layers. Generally, deeper layers are older than layers closer to the surface.
Radiocarbon dating: Measures the decay of carbon-14 in organic materials like wood, bone, and charcoal to find their age (up to roughly 50,000 years old).
Dendrochronology: Counts and compares growth rings in ancient wooden beams to date timber structures precisely.
Thermoluminescence: Measures trapped light electrons in fired clay pots to determine when they were last baked in a kiln.
X-ray fluorescence (XRF): Reveals the exact chemical elements inside metals and rocks without damaging the artifact.

Interpreting Material Culture

Archaeologists study artifacts to understand the daily lives of ancient people. They look for patterns showing what technologies were available and how goods were traded between distant regions.

Experts avoid jumping to quick conclusions about ancient societies based only on their possessions. As the archaeologist Carol Kramer famously noted, "pots are not people." A group of people using Roman pots might not have been Romans; they may have simply bought useful jars through international trade networks.

Protecting Ancient Artifacts and Museum Ethics

Because artifacts provide vital evidence about our shared human history, protecting them from destruction and theft is an urgent global mission.

The Threat of Looting

Looting happens when people illegally dig up ancient sites to steal artifacts and sell them to private collectors. When looters rip an object out of the ground, they destroy its archaeological context forever. A museum or lab can no longer tell which layer of soil it came from or what objects surrounded it.

Debates Over Museum Collections

Many famous museums acquired objects during past centuries under unfair conditions or foreign occupation. Today, countries around the world are working together to address the ownership of historical treasures:

Restitution: Returning cultural items to their countries of origin so local communities can preserve and display their own heritage.
The Elgin Marbles: Ancient Greek marble sculptures taken from the Parthenon in Athens that are currently held in the British Museum, with ongoing discussions about their return.
African Heritage: European museums hold many historic treasures, such as the Benin Bronzes, which several institutions have begun returning to Nigeria.
Global Agreements: International treaties, like the 1970 UNESCO Convention, ban the illegal export and sale of cultural property across national borders.
