A moving picture is an illusion that makes a still photo seem to move. The basic principal behind motion pictures is the fast transition between one picture to the next, almost creating a seamless transition. A flip-book is a good example of this. Another example would be film used for old movies. The film contains negatives of an image which when light is shined through creates a "shadow" of the image. If you quickly transition the film from one image to the next you end up a motion picture.
Wars have been caused with “art” and country have thrived with “art”.
In my opinion art helps keep us all as a whole.
Patrons funded artists and often paid a selection of chosen artists a salary. This injection of money in an artist was often exchanged for artworks and/or commissions, this dramatically helped impoverished artists hone their craft and develop new ideas for artworks. Also, patrons often commission artists to create an artwork with a specific brief or themes that they themselves have chosen, shaping the content of the artwork also.
