西汉鎏金铜蚕是汉代蚕桑业与丝路文化的标志性微缩文物，目前国内仅在陕西石泉等地出土过寥寥数件，其中石泉出土的一件最为完整，全长仅 5.6 厘米，通体以青铜铸造并鎏金，造型模拟吐丝前的熟蚕形态，昂首吐丝、体态丰圆，九对胸足与腹足清晰可辨，工艺极为精巧。这件铜蚕出土于古子午道沿线，而子午道正是汉代由长安通往汉中、巴蜀并连接南方丝绸之路的重要通道，它的发现直接印证了陕南地区在汉代已是重要的蚕桑产地与丝绸贸易节点。
The gilded bronze silkworm of the Western Han Dynasty is an iconic miniature artifact of Han Dynasty sericulture and Silk Road culture. Only a few specimens have been unearthed in China, primarily in Shiquan County, Shaanxi, with the most complete one measuring merely 5.6 centimeters in length. Cast in bronze and fully gilded, it is shaped like a mature silkworm before spinning silk—head raised as if secreting thread, body plump and round, with nine pairs of thoracic and abdominal legs clearly distinguishable, showcasing exquisite craftsmanship. This bronze silkworm was found along the ancient Ziwu Road, a crucial Han Dynasty route connecting Chang’an to Hanzhong and Bashu, and linking to the Southern Silk Road. Its discovery directly confirms that southern Shaanxi was already a major sericulture center and silk trade node in the Han Dynasty.
与体量宏大的青铜礼器不同，鎏金铜蚕以极小的尺寸承载了极重的历史信息。汉代统治者极度重视农桑，皇后每年举行 “亲蚕礼” 以劝勉天下妇女从事蚕织，丝绸更是汉帝国对外贸易与外交馈赠的核心物资。以贵重的青铜鎏金工艺来塑造一只日常可见的家蚕，本身就说明蚕桑在汉代社会经济与国家战略中的特殊地位，它既是古人对 “春蚕到死丝方尽” 的物质致敬，也是丝绸之路起点最生动的微观注脚。
Unlike grand bronze ritual vessels, the gilded bronze silkworm carries enormous historical information in a tiny size. Han Dynasty rulers attached great importance to agriculture and sericulture; the empress held an annual “Silkworm-Rearing Ceremony” to encourage women across the country to engage in silk weaving, and silk itself was the core material for foreign trade and diplomatic gifts of the Han Empire. Using precious bronze gilding to shape an ordinary domestic silkworm itself demonstrates the special status of sericulture in Han Dynasty social economy and national strategy. It is both the ancients’ material tribute to the silkworm that “spins silk until its last breath” and the most vivid microscopic footnote to the starting point of the Silk Road.
