a flapping flame 

Summer set lip to earth's bosom bare,
And left the flushed print in a poppy there:
Like a yawn of fire from the grass it came,
And the fanning wind puffed it to flapping flame.
With burnt mouth red like a lion's it drank
The blood of the sun as he slaughtered sank,
And dipped its cup in the purpurate shine
When the eastern conduits ran with wine.
(Francis Thompson)
