„I will contemplate the spectacle of your sea. The viewpoints of our mountains also offer us the limitless spectacle of immensity. The unfillable void has a calming effect... The sea! The sea with its charms saddens me. In its joyful moods, it makes me think of the laughing tiger; in its sad moods it recalls the crocodile’s tears, and in its roaring fury, the caged monster that cannot swallow me up.“
— Gustave Courbet
