Obviously, this art is fragile and temporary. To preserve it Goldsworthy has to take pictures. And that is one of the most poignant aspects of his artform. Goldsworthy steps into the natural world, creates something, steps out, and then allows natural forces--time, wind, rain, sun, tide--to slowly erase his creation.
To experience more of Goldworthy's art and methods watch the documentary about him entitled Rivers and Tides. As of this writing Rivers and Tides can be streamed on Netflix and the whole film can be viewed on Youtube.
To conclude this introductory post, I hope you can see some connections between Goldsworthy's art the theme of hebel in Ecclesiastes and the refrain to live into the moment.
Goldsworthy's creations are radically transitory. The art is itself hebel, it makes no claim that it will last beyond the moment. The sun will melt, the wind will blow, the tide will roll in. As Ecclesiastes says, "The race is not to the swift or the battle to the strong...but time and chance happen to them all."
In light of the ideas of Ernest Becker, the art of Andy Goldsworthy is not an immortality project trying to deny or outlast death. Death is woven into the very fabric of the art.
