Born in Verona, he went to Venice in 1572 and studied under both Jacopo Sansovino and Danese Cattaneo, and completed many of the latter's works.
He was responsible for the figure of Doge Leonardo Loredan on the tomb which Cattaneo made in Santi Giovanni e Paolo, Venice.
This was his masterpiece, a bas-relief of the saint bringing back to life a man who had been murdered.
Some years later Campagna made another trip to Padua and wrought the bronze tabernacle for in the Basilica of St Antony of Padua, in the Chapel of the Holy Sacrament (Cappella del Santissimo Sacramento, also known as Cappella Gattamelata), in the right aisle.
In Verona there is an Annunciation over the portal of the old Palazzo del Consiglio and a Madonna at the Collegio dei Mercatanti.
