From the time when I saw the great vision until now, there has remained a splendor (O wondrous thing!) about my head; and this is plain to all whom I have thought well to point it out – but these are very few. It is visible above my shadow in the morning, at sunrise, and for two hours after, and still clearer when there is dew upon the grass.
