西汉鎏金兽形铜镇是汉代席居制度的配套生活器物，专门用于压住席子四角以避免起身时席边翻卷，主流造型为豹、熊、鹿、辟邪等瑞兽，以青铜铸造后通体鎏金，部分精品还点缀错金银纹饰与宝石镶嵌。这类镇器高度通常仅 3 至 10 厘米，体量小巧却造型饱满生动，将动物的慵懒姿态与灵动神韵刻画得淋漓尽致，是汉代贵族家居陈设与日常使用的精致物件。随着后世垂足家具普及，席地而坐的起居方式退出主流，铜镇也随之淡出历史，存世完整鎏金品几乎均出自王侯级墓葬。
The gilded bronze beast-shaped mat weight from the Western Han Dynasty was a daily artifact matching the floor-sitting system of the Han Dynasty. It was specially used to hold down the four corners of mats to prevent the edges from curling up when people stood up. The mainstream shapes are auspicious beasts such as leopards, bears, deer and pixiu, cast in bronze and fully gilded. Some fine pieces are also decorated with gold-silver inlay patterns and gem inlays. Usually only 3 to 10 centimeters tall, these weights are small in size but full and vivid in shape, vividly depicting the lazy posture and lively charm of animals. They are exquisite objects for home decoration and daily use by Han Dynasty nobles. With the popularization of high-legged furniture in later dynasties, the floor-sitting lifestyle faded out of the mainstream, and bronze weights also gradually disappeared from history. Almost all surviving complete gilded specimens come from royal and noble tombs.
与青铜礼器、兵器等承载政治军事功能的文物不同，兽形铜镇直接切入古人的日常生活细节，是汉代 “事死如事生” 丧葬观念的微观具象。墓主人会将生前喜爱的席镇随葬，以期在地下世界延续同样精致的起居体验。这些镇器既体现了汉代青铜鎏金工艺的成熟水准，也暗含着古人以瑞兽镇宅、辟邪纳福的精神诉求，是研究汉代社会生活史与审美变迁的珍贵实物。
Different from bronze ritual vessels and weapons that carry political and military functions, beast-shaped bronze weights directly reflect the details of ancient people’s daily life, and are a micro-embodiment of the Han Dynasty’s burial concept of “treating the dead as if they were alive”. Tomb owners would bury their favorite mat weights with them, hoping to continue the same exquisite living experience in the underworld. These weights not only reflect the mature level of bronze gilding technology in the Han Dynasty, but also imply the ancient people’s spiritual pursuit of using auspicious beasts to guard the house, ward off evil and welcome blessings. They are precious physical materials for studying the social life history and aesthetic changes of the Han Dynasty.
