I'm leaving this open to any region in the pre-middle ages because part of me doubts that there are any sources at all about it.

Ancient peoples must have noticed static in a variety of forms, from hair defying gravity, to the little shocks when you touch something while charged, to actually seeing it when it's dark out. The idea of experiencing or seeing static without an explanation sounds mindblowing and almost scary, so I'm wondering how people talked about it.

Are there any explanations or descriptions of static from antiquity? How do they rationalize it?
