What is an Art Movement?
The concept of "movements" in art is usually linked to a specific time (and sometimes place) in history.
For instance, there are painters today who still paint in an Impressionistic manner, embracing the concepts that first defined Impressionism in the 19th century. However, because they are contemporary artists who are inspired by the Impressionists, they are not really part of the original "Impressionist movement" as it exists in historical terms. Although art styles can be resurrected from the past, the movement itself is still anchored in its original position on the art history timeline.
