8月10日，由中国文化和旅游部主办，中国美术学院承办的“艺汇丝路”外国艺术家丝路行访华采风活动在兰州黄河之滨启动。意大利艺术家Matteo Montan来到甘肃炳灵寺石窟后，被红砂岩鲜艳的色彩所震撼。他随即利用当地材料开始创作自己的艺术作品。两天后，在张掖的平山湖大峡谷，他望着那片无边无际的红色说，“我真的很喜欢这种颜色——它和我的家乡意大利有着奇妙的联系。”他解释说，这种红色在意大利语中被称为“锡耶纳土”，源自意大利托斯卡纳地区的一个叫锡耶纳的城市。Upon arriving at the Bingling Temple Grottoes in northwest China's Gansu Province, Italian artist Matteo Montani was struck by the vivid hues of the red sandstone. He immediately began work on his art piece while making use of local materials.Carved into caves along the Yellow River's northern bank in Yongjing county, Linxia Hui autonomous prefecture, the Bingling Temple Grottoes date back to the Western Qin Dynasty (385-431).Two days later, at Pingshan Lake Grand Canyon in Zhangye, he looked out at the vast sea of red and smiled, "I really like this color so much—it has such a wonderful link with my home, Italy." He explained that this kind of red, known as Terra di Siena in Italian, comes from a city named Siena in the Italian region of Tuscany.
