什么意思

以下是引用crystal_z_y在2003-8-20 9:15:00的发言：
语法中的题目，但意思不理解，请帮忙：
the extraordinary diary of W, prime minister of Canada for over 20years,revealed that this most bland and circumspect of men was a mystic guilded in both public and private life by omens,messages received at seances,and signs fron heaven.

men 之前的of 是怎么来的，这句话在说什么？请说明一下，谢谢！
