Callimachus - Heracleitus

The news you were gone, Heracleitus, brought me to tears:
I remembered how many twilights we'd worn out together,
talking the sun to his rest. And now, I suppose,
you are nothing but dust, old friend, in your home far away.
But your nightingales are singing, too quick for the touch
even of death who robs us of everything.

Callimachus
