Final answer:
Analyzing an artist's portrayal of heroes in a work of art mostly reveals their admiration for heroism.
Step-by-step explanation:
When analyzing an artist's portrayal of heroes in a work of art, we can mostly infer that the artist admires heroism.
A good example of this is Goya's painting mentioned in the reference. It depicts an anti-hero being killed on the side of the road, which is a departure from the traditional heroic portrayal in art. However, the painting still evokes strong emotions and captures the essence of heroism.
This suggests that the artist admires heroism but chooses to portray it in a different and more thought-provoking way.
