‘Art’: een etymologische verhandeling
Art has been used in English from the 13th Century. It was widely applied without predominant specialization, until the late 17th Century, in matters as various as mathematics, medicine and angling.
In the medieval university curriculum, the arts were grammar, logic, rhetoric, arithmetic, geometry, music and astronomy. Artist, from the 16th Century on, was first used in this context, though with almost contemporary developments to describe any skilled person.
The emergence of an abstract, capitalized Art, with its own internal but generalized principles, is difficult to localize. There are several plausible 18th Century uses, but it was in the 19th Century that the concept became general.
