Definition of Art

I quickly looked up a few definitions of art, I might use this at the beginning of my book to contextualise everything else.

ART
noun /ärt/ 
arts, plural

The expression or application of human creative skill and imagination, typically in a visual form such as painting or sculpture, producing works to be appreciated primarily for their beauty or emotional power
- the art of the Renaissance
- great art is concerned with moral imperfections
- she studied art in Paris

Works produced by such skill and imagination
- his collection of modern art
- an exhibition of Mexican art
- an art critic

Creative activity resulting in the production of paintings, drawings, or sculpture
- she's good at art

The various branches of creative activity, such as painting, music, literature, and dance
- the visual arts
- the art of photography

Subjects of study primarily concerned with the processes and products of human creativity and social life, such as languages, literature, and history (as contrasted with scientific or technical subjects)
- the belief that the arts and sciences were incompatible
- the Faculty of Arts

A skill at doing a specified thing, typically one acquired through practice
- the art of conversation

My argument would be fulfilled by the first definition and the last two, for sure and so I will probably put all of these definitions in my context book but make sure those definitions are more prominent in the hierarchy than the others are.
