Lucian, Hermotimus 1

Hermotimus quotes the famous first line of Hippocrates’ Aphorisms:

χρὴ δὲ μηδένα καιρόν, οἶμαι, παριέναι εἰδότας ἀληθὲς ὂν τὸ ὑπὸ τοῦ Κῴου ἰατροῦ εἰρημένον, ὡς ἄρα “βραχὺς μὲν ὁ βίος, μακρὴ δὲ ἡ τέχην.”

We must not, I think, pass by any opportunity, knowing as we do that what the Coan doctor said is true: ‘Life is short, but art is long.’
