120 years ago, in a cave near Lisbon, called Boca do Inferno (Hell's Mouth). Back then every second of sea, wave recorded was precious. Seeing this we still get that sense of rarity. No matter how much it is reproduced. We get that people, then, would open their mouths in awe. Even we get a little amazed, in our days, when we think about how images were once rare and so, so powerfull.
