As hamlet of Diano in 1506 once more the Sanseverinos had returned Giacomo, in that year, from the Catholic king. There is news that a part of village, from 1522 to 1599, belonged to Scipione Seripando and to his wife Porzia.

Jacono of Diano ». It misses in the Galanti. Alfano says of its 2530 inhabitants. Giustiniani says few of « St. Giacomo or Saint Jacovo of Diano », as the village was designate in the numerations. It is situated 44 miles away from Salerno with 500 inhabitants among agriculturists and shepherds.
