"The shrines of old are broken down"

The shrines of old are broken down;
The faiths that knelt at them are dead.
Nothing's strange, and nought unknown:
All's been done and all been said.
Tired of knowledge, now we sigh
For a little mystery.
Yet, howsoever science delves,
A few things still unplumbed remain.
We know all things save ourselves,
Cannot will our joy or pain.
Mysteries our hearts enthral;
And love's the strangest of them all.
