The Human Seasons / John Keats

Four seasons fill the measure of the year;
There are four seasons in the mind of Man:
He has his lusty Spring, when fancy clear
Takes in all beauty with an easy span:
He has his Summer, when luxuriously
Spring's honeyed cud of youthful thought he loves
To ruminate, and by such dreaming high
Is nearest unto heaven: quiet coves
His soul has in its Autumn, when his wings
He furleth close; contented so to look
On mists in idleness -to let fair things
Pass by unheeded as a threshold brook: - 
He has his Winter too of pale misfeature,
Or else he would forgo his mortal nature.
