Answer 3

First, if you have a question, it is much better to put it in as a separate post in <Post a New Question> rather than attaching it to a previous question, where it is more likely to be overlooked.

Since this is not my area of expertise, I searched Google under the key words "compass inventor" to get these possible sources:
