【传世佳作究竟出自谁人之手？】《写生蛱蝶图》描绘了夏日菜园一角——草丛间蝴蝶飞舞，菜叶上蚱蜢随风摇摆的惬意景色。这件作品虽传为北宋画家赵昌所绘，但实际画幅上却没有赵昌的题款和印章。究竟这幅画是不是出自赵昌之手？明代董其昌在画的后面题了一个观款，称这幅画是赵昌所作。他的鉴定意见能否采信？故宫博物院研究馆员杨丹霞为您解答。"Butterflies Sketched from Life" captures a charming summer garden scene with butterflies and grasshoppers. Although this is known to be Northern Song Dynasty (960-1127) artist Zhao Chang's work, it doesn't bear his seal or inscription. So, did he paint it or not? In the back, there is an inscription by Dong Qichang, a well-known painter, connoisseur and painting and calligraphy theorist from the Ming Dynasty (1368-1644), stating it to be the work by Zhao. Can we rely on Dong's appraisal of this work? Yang Danxia, a research fellow at the Palace Museum, provides insights. #入画#千年调宋代山水花鸟#数字特展入口：http://t.cn/A6lKqSFi http://t.cn/A6lD1RfQ
