OTRANTO, or TERRA D'OTRANTO, a province of Italy in the kingdom of Naples; bounded on the north by the Terra di Bari and by the gulf of Venice, on the east by the same gulf, and on the south and west by a great bay which is between that and the Basilicata. It is a mountainous country, abounding in figs, olives, and wine. It is often visited by locusts, and by Algerine pirates, who carry off all the people they can catch into slavery. But to keep them off, there are a great many forts on the coasts.
