Throughout history, many artists have tried to capture the image of what they feel their gods or goddesses are. Many of these pieces have become the most valuable contributions and the most sought-after collections of the art world.
Artists of all methods, such as painters and sculptures, have tried to capture the sublime feeling of one's own higher power. Not only limited to the ultimate divinity, many have tried to capture other spiritual creatures such as angels and their arch enemies, demons.
Michelangelo Buonarroti and the painting of the "Creation of Adam" on the Sistine Chapel is one of the first things that come to mind when thinking about the definition of religious art. Examples of canvas work include "Madonna" by Gentile da Fabriano and El Greco's "Trinity," both of which can be considered classic examples of religious art.
The popular misconception of critics and appreciators alike is that only pieces of a mainstream Christian nature can placed in the category. Work that showcases mythology, Mother Earth and other supreme beings of past and present worship can also be grouped within this subject.
With all of the broad terms that can go into defining what an artistic piece should be considered as, it basically means that any example of artwork could be considered spiritual if that is how the viewer sees it. When decorating you home, you can either go classic or buy decor that matches your own definition of religious art.
