I hope you won't mind the Greek accent (after all, Cavafy himself was Greek ^_^ ). The translations are my own as well. Any feedback would be welcome
1. Poseidonians
Poseidonians*
The Greek language was forgotten by the Poseidonians
as they mingled for so many centuries
with Tyrrhenians, and Latins, and other foreigners.
The only thing they had left from the forefathers
was a Greek festival, with beautiful rites,
lyres and flutes, games and wreaths.
And they were of the habit, each time the festival was reaching an end,
to narrate their old customs,
and to speak once again the Greek names,
those names that by now only few could understand.
And their festival would always end with melancholy.
For they recalled that they too had been Greeks --
They came to Italy as colonists;
and how had they fallen now, how did they become this,
living and speaking barbarically,
disastrously displaced from Hellenism.
*Poseidonia was the old, Greek name, replaced with "Paestum" when the city was incorporated into non-Greek dominions.
