“After Stéphane Mallarmé, after Paul Verlaine, after Gustave Moreau, after Puvis de Chavannes, after our own verse, after all our subtle colour and nervous rhythm, after the faint mixed tints of Conder, what more is possible? After us the Savage God.”
—William Butler Yeats (1865–1939)
“This pond never breaks up so soon as the others in this neighborhood, on account both of its greater depth and its having no stream passing through it to melt or wear away the ice.... It indicates better than any water hereabouts the absolute progress of the season, being least affected by transient changes of temperature. A severe cold of a few days’ duration in March may very much retard the opening of the former ponds, while the temperature of Walden increases almost uninterruptedly.”
—Henry David Thoreau (1817–1862)
