Epigraph: But now farewell. I am going a long way / With these thou seest - if indeed I go - / (For all my mind is clouded with a doubt) / To the island-valley of Avilion; / Where falls not hail, or rain, or any snow, / Nor ever wind blows loudly; but it lies / Deep-meadow'd, happy, fair with orchard-lawns / And bowery hollows crown'd with summer sea, / Where I will heal me of my grievous wound - Tennyson, 'Morte d' Arthur'.
And sometimes it works in a circle - Sarrow.
