πίε, φάγε, τρύφησον, ἀφροδισίασον,I haven't seen Corsten's book. The Greek text above comes from the Packard Humanities Institute's Searchable Greek Inscriptions, here. My translation:
τὰ δὲ ὧδε κάτω σκότος.
χαίρετε, παροδῖται.
Drink, eat, have fun, make love.For other epitaphs of this sort see Richmond Lattimore, Themes in Greek and Latin Epitaphs (1935; rpt. Urbana: University of Illinois Press, 1962), pp. 260-262.
Down here? Darkness.
Farewell, passers-by.
