Saved, put on a reading list.
History's weakness it's reliance on written sources. Our perception will always be distorted by Roman, Greek (then Byzantine), Persian and Chinese views on the people who lived north (in general sense) of them. Lacking in writing or - those who had a writing system - in literature or - due to climate, not proper storage conditions, etc. - in preserved written works, history have to rely on what the neighbours noted about these "barbarians". And this will be lopsided and full of gaps.
Archaeology was a great addition to the toolbox for those who research the past. Too bad remains can't talk, interpretations can be faulty as well and many questions still remain unanswered. For now.
