So I have been thinking of doing a few articles apart from feature articles to link some useful resources for artists and this is the first one of these.
Creating a concept about a civilization, a person or even a fantasy environment requires some solid background knowledge and learning about past civilizations' art helps in that regards. "'Should I create abstract patterns on the arches and pillars? Would placing a crosses around a minar look out of place?" "No way I do what I want!!" Surely, a lot of us have gone through those decisive moments.
The Metropolitan Museum of Art
(MET) has several free fully illustrated books about several references. Below are some of MET's Civilization artbooks which are fully illustrated and full of information. But don't hesitate to research more through your own libraries and art galleries!
