Once in his life, a man ought to concentrate his mind upon the remembered earth. He ought to give himself up to a particular landscape in his experience; to look at it from as many angles as he can, to wonder upon it, to dwell upon it.– N. Scott Momaday, "XXIV" from "The Way to Rainy Mountains"Classical antiquity recognized just four elements — air, earth, water and fire — from which everything had been made. These four no longer explain the world, but they retain, at least for me, a poetic capacity — a way of wondering upon where I am.D. J. Waldie is the author of "Becoming Los Angeles: Myth, Memory, and a Sense of Place." This series of essays called “Elemental L.A.” explores an Angeleno “sense of place” using the four classical elements as guides.
