Following earlier releases on July 5 and December 10 of 2019, Chunghwa Post has issued a new set of four stamps on jades of the National Palace Museum. Descriptions of their designs follow:1. Jade Bird, Hongshan culture (NT$8): The people of the neolithic Hongshan culture believed that birds provided a communication channel between heaven and earth and served as ambassadors between gods and men. In those ancient times, they selected jade, which perfectly embodies the essence of nature, to carve bird images. Carved with soft lines, this jade bird conveys a difficult-to-measure sense of spiritualism. 2. Jade Ornament with Divine Animal-mask Pattern, Liangzhu culture (NT$9): Liangzhu culture’s jade objects were closely connected to the culture’s religious beliefs, and they frequently took god figures with animal masks as their subject matter. The animal mask here has a pair of large eyes, a wide-open mouth, sharp fangs protruding from both the top and bottom of the mouth, and a sharp point at the top, which represents the tip of the feathered headdress of a god. Liangzhu culture often used simple pointy tips to represent the whole body of a god.3. Jade Cong Tube, Longshan-Qijia culture (NT$17): This work has a cylindrical interior and square exterior. Representing heaven and earth, it was an important ritual object in Longshan-Qijia culture. It has beautiful proportions, bearing witness to the meticulous approach taken to its manufacture. Simple and elegant, it reflects the solemnity of the religious rites in which it played a role. 4. Jade Disc with Raised Rim, Shang dynasty (NT$22): It is made of a dark jade commonly found in objects dating to the Shang dynasty. The central hole of the disc is small, and its face is thin and wide and features a series of delicate concentric circles. It bore special meaning as an object in religious ceremonies, and it was not used as an ornament in everyday life.
