In Paradise Lost 5, Eve recounts the dream Satan inspired in her, in which she imagines approaching the Tree of Life, and it is the smell of the tree that opens her senses to its taste:
That brought me on a sudden to the Tree
Of interdicted Knowledge: fair it seem’d,
Much fairer to my Fancie then b...
A scent of ripeness from over a wall.
And come to leave the routine road
And look for what had made me stall,
There sure enough was an apple tree
That had eased itself of its summer load,
And of all but its trivial foliage free,
Now breathed as light as a lady's fan.
For there there had been an apple fall
As complete as the apple had given man.
The ground was one circle of solid red.
May something go always unharvested!
May much stay out of our stated plan,
Apples or something forgotten and left,
So smelling their sweetness would be no theft.
Unharvested was written by Robert Frost.
