I found this one very hard. What is wisdom, how to depict it. Wisdom to my mind comes from experience and the ability to reflect and learn, but also conveys a passing on of that knowledge. The knowledge has to stand the test of time too, I think. So my picture had to encompass all of that. But what?
A school , a church, a library. No Books, and which books, well a couple of books full of wisdom which have to my mind met the criteria.
