An artist is a person engaged in an activity related to creating art, practicing the arts, or demonstrating an art. The common usage in both everyday speech and academic discourse refers to a practitioner in the visual arts only. However, the term is also often used in the entertainment business, especially in a business context, for musicians and other performers (although less often for actors). "Artiste" (French for artist) is a variant used in English in this context, but this use has become rare. The use of the term "artist" to describe writers is valid, but less common, and mostly restricted to contexts such as critics' reviews.
The Oxford English Dictionary defines the older broad meanings of the term "artist":
A learned person or Master of Arts.
One who pursues a practical science, traditionally medicine, astrology, alchemy, chemistry.
A follower of a pursuit in which skill comes by study or practice.
A follower of a manual art, such as a mechanic.
One who makes their craft a fine art.
One who cultivates one of the fine arts – traditionally the arts presided over by the muses.
The Greek word "techně", often translated as "art", implies mastery of any sort of craft. The adjectival Latin form of the word, "technicus",
became the source of the English words technique, technology, and technical.
In Greek culture, each of the nine Muses oversaw a different field of human creation:
Calliope (the 'beautiful of speech'): chief of the muses and muse of epic or heroic poetry
Clio (the 'glorious one'): muse of history
Erato (the 'amorous one'): muse of love or erotic poetry, lyrics, and marriage songs
Euterpe (the 'well-pleasing'): muse of music and lyric poetry
Melpomene (the 'chanting one'): muse of tragedy
Polyhymnia or Polymnia (the '[singer] of many hymns'): muse of sacred song, oratory, lyric, singing, and rhetoric
Terpsichore (the '[one who] delights in dance'): muse of choral song and dance
Thalia (the 'blossoming one'): muse of comedy and bucolic poetry
Urania (the 'celestial one'): muse of astronomy
No muse was identified with the visual arts of painting and sculpture.
