It had been startling and disappointing to me to find out that story books had beenwritten by people, that books were not natural wonders, coming up themselves like green grass.

-Wu-ti
c.127  BC  'TheAutumnWind' (translated byArthurWaley).The poem is a lament on leaving his mistress behind while he travelled on official business.

Down by the salley gardens my love and I did meet; She passed the salley gardens with little snow-white feet. She bid metake love easy, asthe leavesgrow on thetree; But I, being young and foolish, with her would not agree. In a field by the river my love and I did stand, And on my leaning shoulder she laid her snow-white hand. She bid metake life easy, as thegrassgrows on the weirs; But I was young and foolish, and now am full of tears.

And walk among long dappled grass, And pluck till time and times are done The silver apples of the moon, The golden apples of the sun.
