What is a key feature of european renaissance culture

I would say a key feature of the European Renaissance culture would be that, because of the Renaissance, things such as reading and knowledge of things became much more popular, creating a more educated population. Classical literature became popular once again too. There was also the fact that humanism emerged during this era, which was basically the individual thought and self-admiration of human beings rather than human beings being despicable, unworthy beings under God. People like Michelangelo, Da-Vinci, and Raphael were amazing artists that could show examples of humanism in their artworks, especially da-vinci with his sketches. hope this helps ya :)
