This poem was composed in the late Kaiyuan era of Emperor Xuanzong (around 741 CE), representing Du Fu's early style of using the description of an object to voice his aspirations. It was a time known as the "flourishing zenith of Kaiyuan." The young Du Fu was roaming the regions of Qi and Zhao, leading a spirited and untrammeled life, his heart filled with the grand ambition to "make my sovereign surpass the sage-kings Yao and Shun, and restore anew the customs pure and true." The painting of an eagle celebrated in this poem, though its artist is unknown, possessed a heroic, keen spirit that resonated deeply with the poet's own youthful longing to display his prowess and sweep away the mediocre. This painting was not merely an artistic subject but a projection of the poet's ideal self and a declaration of his vibrant, youthful vitality.
