# Castle on a Hill [View the canonical artwork record]() ## Artwork - Artist: [UNKNOWN MASTER, Italian]() - Date: 1301-1350 - Technique: Fresco ## Commentary During restoration work in 1979-80 in the Sala del Mappamondo of the Palazzo Pubblico in Siena, a new fresco was discovered below the imposing Guidoriccio da Fogliano by Simone Martini, representing a castle on a hill and two people in the foreground. The attempt to discover the identity of the unknown author of this work has given rise to much controversy among critics. Duccio, Pietro Lorenzetti, Memmo di Filippuccio, Simone Martini were suggested. The fresco, of outstanding executive quality both in skilful choice of descriptive detail and in its overall coherence, was badly damaged by the Mappamondo, a large, revolving, circular painting by Ambrogio Lorenzetti, which was placed on top of it in 1345. ## Related artworks - [A Bishop Saint]() - [A Curious Scene]() - [Adam and Eve; Cain and Abel]() - [Adoration of St Mark]() - [Allegorical Portrait of Dante]() - [Altar frontal]() - [Altarpiece \(detail\)]() - [Altarpiece of St Clare \(detail\)]() - [Altarpiece of St Clare \(detail\)]() - [Altarpiece of St Clare]() - [Altarpiece of the Magi]() - [Altarpiece]() ## Attribution [Web Gallery of Art]()
