Socrates: .....but let me ask you, friend: have we not reached the plane-tree to which you were conducting us?

Phaedrus: Yes, this is the tree.

Socrates: By Here, a fair resting-place, full of summer sounds and scents. Here is this lofty and spreading plane-tree, and the agnus cast us high and clustering, in the fullest blossom and the greatest fragrance; and the stream which flows beneath the plane-tree is deliciously cold to the feet. Judging from the ornaments and images, this must be a spot sacred to [Achelous] and the Nymphs. How delightful is the breeze:-so very sweet; and there is a sound in the air shrill and summerlike which makes answer to the chorus of the cicadae.
