And all of a sudden it makes clear things like the flute, the flute from Hohle Fels Cave [in Germany], which is mammoth ivory, and the tiny fragments that were not understood for decades, but they were preserved.
That's a fine thing, yes, until somebody came who had the kind of imagination like the young woman who is in the film, Maria Malina, an archaeological technician who had the insight and started to put the fragments together.
Bronzes and other objects are often restored with distilled water, which does not remove the patina (the thin coating that forms on stone, ceramic or metal over centuries).
The patina us often checked to determine whether an object is real or fake.
Ancient people rarely threw out what was valuable to them.
