Sacra conversazione : the madonna and child with saints luke and catherine of alexandria .

神圣的对话：圣母和孩子与圣路加和亚历山大凯瑟琳。

Please forgive my not writing this passage in english for even though with the mother language , it was still a little bit difficult to make it as a highly spiritual conclusion to the conversazione , let alone english .

因为需要对座谈会作一个比较有高度的总结，用母语写作本文已经有点困难，所以没有用英语，请见谅。
