I'm a big fan of the nature artist Andy Goldsworthy. In his art he only uses found natural materials: leaves, twigs, flowers, icicles, dirt. From these natural bits he builds amazing temporary arrangements outdoors in the natural settings he finds the material. He photographs their brief existence as a new order and then lets the elements unravel them. For a moment, his fanciful designs capture some invisible spirit that is both completely wild and completely Andy Goldsworthy. Once you see one of his natural sculptures, they seem to be inevitable. A rainbow row of leaves sorted by color. Of course! You can't forget them. Again and again he seems to summon archetypes – an icicle arch – that ought to occur in the wild. But we don't see them until he unveils them. Goldsworthy is a prolific maker, with many books of his stunning works. If I had to select only one volume, I think his Collaboration with Nature has the best summary of his early work (up to 1990). I take these as visual poems. If they ring a bell in you, proceed to his later work.
