Epicurus, The Extant Remains, translated by Cyril Bailey (Oxford: The Clarendon Press, 1926).
Epicurus wrote this brief note to a member of his school while on his death-bed:
On this blissful day, which is also the last of my life, I write this to you. My continual sufferings from strangury and dysentery are so great that nothing could increase them; but I set above them all the gladness of mind at the memory of our past conversations. But I would have you, as becomes your lifelong attitude to me and to philosophy, watch over the children of Metrodorus.
