The phrases build up the theme of contrast and balance in beauty in this poem of Lord Byron are:
"And all that’s best of dark and bright
Meet in her aspect and her eyes."

Is used by George Orwell to complete disapproval of human vices (bad habits and ongoing steps most of the time from vices/"humans") such as insatiable hunger for power.
