If séances are a kind of collective remembrance,

如果说降神会是一种集体性的回忆活动
they created, as it were,

那么他们似乎开创了先例
the precedent for the ones that have left their most powerful marks,

认为死者在欧洲以及其他一些地方
not only on Europe but beyond it, as well.

都留下了强而有力的痕迹
These are war memorials.

这些都是对战争的纪念
The need to create a substitute tomb, a substitute place

这就需要有一些东西来代替坟墓代替墓地
in front of which to mourn,

以便人们悼念亡者
is what creates the extraordinary vogue of war memorials.

这就产生了一些新颖时尚的纪念活动
You don't have to go very far to see them.

人们不必跑老远去悼念亲人
All you have to do is go through Commons,

他们只需走过下院
and you'll see two war memorials that were created at the same moment,

就可以看到那两家同时建立的战争纪念馆
right after the First World war.

那时一战刚刚结束
