Artist like any other human been, are trying to understand, and explain the world to others, and to themselves, they use their experiences, and imagination, in order to make sense of the world , tangible, or intangible, to do this the artist assume four roles, Henry M. Sayre in his book “A World of Art” define those roles as:
1) Artist help us to see the world in new or innovative ways:
In this role the artist will produce a piece that generate a new sensation, or a new way of thinking, as an example the artist Yayoi kusama in her work, “You Are Getting Obliterated in The Dancing Swarm of Fireflies”,2005, she create a room who’s walls, ceiling, and floor is covered by mirrors, inside the room is and assortment of led lights hanging from tiny wires above the ceiling, went the spectator enters the room immediately feels the sensation of been in space, floating, and his/her persona perceive the sensation of been diminished by immensity of the space, created by the illusion of the mirrors.
Another example is artist Xia Xiao Wan (Innovative Art Ideas), he will paint multiple layers of glass separately with semi-translucent colors, all six facets of the sheet will be painted, and then put together in groups forming a cube, offering a new and unique experience for the paint spectator, a 360 degree viewing angle, instead of the traditional two dimensional paints.
2) Artist make a visual record of the people, places, and events of their time and place:
At times the artist just want to record an event, person or an object, sometimes to impartially describe it, or to appreciated it, or to criticize it, two of the most used forms of art for this purpose are, painting, and sculpture. In the painting “Jahangir in Darbar”, 1620, it shows the muslin ruler of India Jahangir seated in his court during and audience, is easy to deduce the diversity, and acceptance of Jahangir court, by the faces,
