失落的世博会金牌奖——吴鲁衡日晷、罗盘考辨

摘要

万安罗盘曾被认定为2010年上海世博会特许商品和行政礼品，媒体纷纷报道这是万安罗盘继1915年获巴拿马世博会金牌奖后再续世博缘。各种文献中对于“万安罗盘获巴拿马世博会金牌奖”的记载却各执一词、互有抵牾。经历史考察及田野调查，1915年应为安徽休宁吴鲁衡毓记出品的日规（晷）在美国巴拿马世博会上获金牌奖。对吴鲁衡日晷、万安罗盘制作技艺进行传承和保护。要避免急功近利的短视做法。%Wan' an compass was designated as the licensed product of The World Exposition 2010 Shanghai China. It's reported that it was the second time for Wan' an compass to gain world exposition gold medal after The World Expo 1915 Panama. Opinions are divided among documents as to the record that Wan" an compass won gold medal in The World Expo 1915 Panama. This paper proves that it was Wu Luheng sundial that gained the World Exposition gold medal in 1915 Panama based on history and field investigation, and suggests that the passed making technique of Wu Luheng sundial and Wan" an compass be on and protected avoiding the shortsighted practice of being eager for instant success and quick profits.
