Nestor's cup, found in Ischia, is considered one of the oldest surviving Greek texts. The text hints at a passage from the Iliad and invites to drink and love. The script is classified as that of euboian western colonies and runs right to left. Let us know if you can actually tell it is Greek without knowing it.
Νεστορος [ἐρροι] εὐποτ[ον] ποτηριο[ν]
ὁσδα τοδε π[ιεσι] ποτηρι[ο] ηὐτικα κενον
ἱμερ[ος αἱρ]εσει καλλιστε[φα]νο Ἀφροδιτες
Nestor's cup was fine for drinking, but whoever drinks from this bowl will be at once sized by desire of beautifully crowned Aphrodite.
