ah! sunflower

by william blake
ah, sunflower, weary of time,
who countest the steps of the sun;
seeking after that sweet golden clime
where the traveller's journey is done;

where the youth pined away with desire,
and the pale virgin shrouded in snow,
arise from their graves, and aspire
where my sunflower wishes to go!
