The term "art consequent on" refers to any art form that is developed or created as a result of another art form. The antonym for this term would be a form of art that is not developed or created as a result of another art form. Instead, it would be an original or self-created art form that is not dependent on any other art form. This could include art forms that are inspired by nature, personal experiences, or other sources of inspiration that are not necessarily related to other art forms. Examples of such art forms could include abstract art, folk art, or even performance art that is based on personal expression rather than the influence of other art forms.
