English Art/Literary General / Conversation / Greetings / Letters

The word occurs in an epigram found in the ancient city of Herculaneum in Italy (an quoted in S. Greenblatt's "The Swerve"), so it is from an ancient text. The epigram itself invites a friend, Piso, to come and celebrate a monthly feast in honour of Epicurus:

"Tomorrow, friend Piso, your musical comrade drags you
to his modest
digs at three in the afternoon,
feeding you at your annual visit to the Twentieth. If you
will miss udders
and Bromian wine mis en bouteilles in Chios,
yet you will see faithful comrades, yet you will hear
things far sweeter
than the land of the Phaeacians..."

I assume the adjective "Bromian" is referring to a place name, but even if so, I couldn't find what it is.
