My questions are pretaining to the weather vane/wind vane who developed the tool? When was it developed?

Question

What is it made of?
How accurate is it?
How does it work?

Answer 1

The weather vane has probably been around as long as the wheel has. I am quite sure the Greeks or the Egyptians or even the Persian or Babylonian empires had them. And I'm sure it was found serendipitously. The wind vane rotates freely on a vertical rod and becomes aligned by the direction of the wind. A vane can be made of most any material - wood, cloth, copper.
