Palladio was first discovered by Trissino while working as a stonemason rebuilding Villa Trissino around 1530. Trissino would then have Palladio study at his academy, which was this very same building. While learning here, Palladio had the opportunity to meet with a variety of people, like the aristocracy of surrounding regions, who would go onto employ him later in life.
