Chapter 1
Section 5
What is archaeology? • Archaeology is the
study of remains of past human life—which
began 500 years ago.• Archaeologists study artifacts or things
made by people. • Archaeologists excavate or dig in the
earth and attempt to understand how people
lived long ago.
Artifacts• Why do we study
artifacts?– Not many written
records from ancient times
• Examples: – art– weapons– tools– pottery
Important Archaeological Finds
• Ancient Roman cities of Herculaneum and Pompeii– showed exactly how ancient Romans lived– found streets, temples, houses, and
theaters
• Rosetta Stone– Carved stone found in Egypt– contained translation from Egyptian picture
writing to Greek…a two-language dictionary
– was a key to learn more about history of Egypt and its people.
Dating Archaeological Remains• In 1832, scientist Christian J.
Thomsen divided early human history into three ages or periods
based on tools or weapons used by
people at the time.– Stone Age– Bronze Age– Iron Age
• Later divided by how they got their food: food gatherers (gets food from hunting, fishing, etc.) then food producers (farming, domesticate animals, etc.)
Dating Archaeological Remains
• Trees were first used to date archaeological finds-each year trees form a new growth ring• Scientists would count rings from a
wooden object found at a sight, and compare it to the age of a tree they knew
• Carbon 14 dating– discovered by Willard Frank Libby– Every living thing contains carbon 14,
which gradually disappears over time– Can date an object as far back as
30,000 years ago
