Thoreau writes in his journal:
It was as if the air, purified by the long storm, reflected these few rays from side to side with a complete illumination, like a perfectly polished mirror, while the effect was greatly enhanced by the contrast with the dull dark clouds and somber earth. As if Nature did not dare at once to let in the full blaze of the sun to this combustible atmosphere. It was a serene, elysian light, in which the deeds I have dreamed of but not realized might be performed. At the eleventh hour, late in the year, we have visions of the life we might have lived. No perfectly fair weather ever offered such an arena for noble acts. it was such a light as we behold but dwell not in! . . .
