Translation of last two verses, more or less-

3
The moon hangs above the ruins,
Unchanging, for whom does it shine?
Nothing clings to the walls but tendrils.
Only the storm sings among the pine boughs.
4
The moon and sky above are unchanging,
In life, there is ebb and flow;
Is the moon there to reflect these changes?
Ah! the moon over the desolate castle.
