Which of the following is an element of Neo-Classicism? patriotic subject matter, loose unfinished brushstrokes, subjectivity, or dark mystic themes. I think it is patriotic subject matter.

Here is one definition

"neoclassicism appears to be a natural expression of a culture at a certain moment in its career, a culture that is highly self-aware, that is also confident of its own high mainstream tradition, but at the same time feels the need to regain something that has slipped away" This might be defined as patriotic.
