Eutrapelia. "A happy and gracious flexibility," Pericles calls this quality of the Athenians...lucidity of thought, clearness and propriety of language, freedom from prejudice and freedom from stiffness, openness of mind, amiability of manners.

Screen'd is this nook o'er the high, half-reap'd field,
And here till sundown, Shepherd, will I be.
Through the thick corn the scarlet poppies peep,
And round green roots and yellowing stalks I see
Pale blue convolvulus in tendrils creep:
And air-swept lindens yield
Their scent, and rustle down their perfumed showers
Of bloom on the bent grass where I am laid,
And bower me from the August sun with shade;
And the eye travels down to Oxford's towers...
