Art may be characterized in terms of mimesis (its representation of reality), expression, communication of emotion, or other qualities. During the Romantic period, art came to be seen as "a special faculty of the human mind to be classified with religion and science".[2] Though the definition of what constitutes art is disputed[3][4][5] and has changed over time, general descriptions mention an idea of imaginative or technical skill stemming from human agency[6] and creation.[7]
The nature of art, and related concepts such as creativity and interpretation, are explored in a branch of philosophy known as aesthetics.[8]
