2. Incomplete Record  Tendency to ignore the mundane  Elitism, disdain for manual work  Secrecy and isolation  Destruction of documents  Destruction of artifacts  Uncertain dates, identification of persons, unclear descriptions

3. Uncertain Interpretation of Artifacts  Many Artifacts are of Unknown Purpose  Purpose--may or may not have been practical  How made? One way to answer is to reproduce it using ancient methods

4. Fallacies of Reasoning  Oversimplification  Determinism, linear view of history.  “You can’t stop progress”  The “Voltairean Fallacy”  “You can’t turn back the clock”  Post Hoc ergo Propter Hoc (after this, therefore because of this)

5. Oversimplification Real issue is that theory leads to wrong conclusions Validity, not simplicity, is the issue Simplicity does not make an idea wrong

6. Cultural Biases
