“That no life lives forever;
That dead men rise up never;
That even the weariest river
Winds somewhere safe to sea.”
– ‘The Garden of Proserpine’ by Algernon Charles Swinburne
I’m not sure if that’s a real poem but I found that quote in The Slippery Slope by Lemony Snicket.
The Series of Unfortunate Events is a great read – I’d recommend it!
