ニューヨーク・タイムズさんのインスタグラム写真 - (ニューヨーク・タイムズInstagram)「In 1971, the artist Charles Ross conceived “Star Axis,” an 11-story naked-eye observatory made of sandstone, bronze, earth, granite and stainless steel. Now, almost 50 years later, the gargantuan work in the New Mexico desert is nearing completion.⁣ ⁣ Ross — one of the last men standing of the generation of so-called earthworks artists — has labored continuously on “Star Axis” for 45 years. He hopes it will be completed in late 2022, when he is 84 years old.⁣ ⁣ “Star Axis” is aligned perfectly with the celestial pole (marked by Polaris, the North Star) and is meant to embody an astronomical phenomenon called precession. First noted around 130 B.C. by Hipparchus, the Greek astronomer who is also credited as the inventor of trigonometry, precession refers to the top-like wobble of the earth’s axis due to the sun’s gravitational pull on the slightly bulging Equator. The result of precession is that while Polaris, found in the constellation Ursa Minor, is currently the closest bright star to the northern celestial pole, that will change over time, as other bright stars from surrounding constellations happen to slowly become the polestar. (The entire cycle takes about 26,000 years.) “How could I not want to illustrate that,” Ross said. “How could I not want to find a way to walk through time?”⁣ ⁣ Tap the link in our bio to read more from @tmagazine about the land art pioneer’s adventures in time and space.
