当卢是古代装饰于战马额头的配饰，西汉鎏金青铜当卢是汉代贵族马具中的小众珍品，区别于常见的铜镜、铜鼎等青铜重器，它器型小巧却工艺极尽奢华。整体呈叶形或盾形，以青铜为胎，通体鎏金，表面常錾刻云气纹、神兽纹与几何纹样，部分还镶嵌绿松石与玛瑙，在阳光照射下金光流转，是汉代尚武精神与奢华审美结合的产物。
Danglu is an ornament decorated on the forehead of war horses in ancient times. The gilded bronze danglu of the Western Han Dynasty is a rare treasure among the horse gear of Han Dynasty nobles. Different from common bronze vessels such as bronze mirrors and tripods, it is small in shape but extremely luxurious in craftsmanship. It is usually leaf-shaped or shield-shaped, made of bronze base and fully gilded. Its surface is often engraved with cloud patterns, mythical beast patterns and geometric motifs, and some are inlaid with turquoise and agate. Glittering in the sunlight, it embodies the combination of martial spirit and luxurious aesthetics of the Han Dynasty.
这类器物多出土于王侯级别的高等级墓葬，墓主多为战功显赫的武将或皇室宗亲，是身份等级的重要象征。由于埋藏环境复杂，完整保存至今的鎏金青铜当卢数量极少，且多数纹饰模糊不清。完好的传世品大多藏于地方考古库房，极少在常设展览中展出，因此大众对其认知度很低，是青铜文物中十分小众的门类。
Such artifacts are mostly unearthed from high-level tombs of princes and marquises, whose owners were mostly generals with outstanding military exploits or imperial relatives, serving as an important symbol of social status. Due to the complex burial environment, very few gilded bronze danglu have been completely preserved to this day, and most of them have blurred patterns. Most well-preserved pieces are stored in local archaeological warehouses and rarely exhibited in permanent exhibitions, so they have very low public recognition and are a very niche category of bronze cultural relics.
