Listen to the story
Among the Aeolian Islands off Sicily, the map marks a small island called Insula Dyme, today's Salina. Ancient writers such as the geographer Ptolemy, the Greek geographer Strabo and the Roman writer Pliny knew it as Didyme, Greek for 'the twin', a fitting name for an island formed by two extinct volcanic cones. On the Tabula the first syllable seems to have dropped out during copying, leaving a name no ancient source uses. The island later became the seat of a bishop.
