When my father was young, he would read adaptations of Greek myths. He thought that Persephone (purse-eph-oh-nee), the queen of the underworld, was pronounced "purse-eh-phone." He also thought that Penelope (pen-ell-oh-pee), the wife of Ulysses, was pronounced "Pen-ell-lope" (rhymes with "cantaloupe.") It actually took him a long time to adjust to the correct pronunciations.
