我這本在序章前的那一頁寫到:
(照打... 希望沒有版權的問題)
Fact:

The Priory of Sion -
a European secret society founded in
1099 - is a real organisation.
In 1975... (略)

The Vatican prelature... (略)
... Opus Dei has just completed construction
of a $47 million National Headquarters at
243 Lexington Avenue in New York City.

All descriptions of artwork, architecture,
documents and secret rituals in this novel
are accurate.

我照打的大致意思是說錫安 (這樣翻的嗎?) 是真的存在,
喔普斯迪 (我在這樣亂翻可能有人要打我了 ) 最近在美國紐約市成立了一棟建築,
也就是說喔普斯迪也是存在的.
再來的就是所有美術作品, 建築物, 文件, 最重要的是所有的儀式都是正確的
