Remains of Kaibao Canon 開寶藏: Song Emperor Taizong's Mizangquan 秘藏詮 at Harvard Art Museum

I made a research trip to Harvard Art Museum a few weeks ago to examine the Song Emperor Taizong's Mizangquan 秘藏詮 (Expounding the Secret Treasure Store) which is one of the thirteen remaining scrolls from Kaibao Canon 開寶藏 carved in 983 in Chengdu. (This one was carved later in Kaifeng, however.) Two years ago, the museum was under construction and I was not able to see it. Now our paper on Kaibao Canon was published and we discussed this piece of art work in our book Spreading Buddha's Word in East Asia: The Formation and Transformation of the Chinese Buddhist Canon, page 160.
