Pompeo Marchesi (Italian pronunciation: [pomˈpɛːo marˈkeːzi; -eːsi]; 7 August 1783 – 6 February 1858) was a Lombard sculptor of the neoclassical school.
One of his earliest works was a larger than life statue of St. Ambrose, patron of the city, for the Duomo of Milan.
For the Arco della Pace (commemorative arch now in the Parco Sempione), completed in 1838, he made various reliefs including of Terpsichore and Venus Urania, and of the rivers Adige and Tagliamento.
He decorated the façade of the Castello with twelve figures of great Italian captains, and that of the Palazzo Saporiti with reliefs in modern classic style.
Works outside Milan include the larger than life statue of Charles Emmanuel III in Novara; that of Philibert Emanuel of Savoy in Turin; the sitting figure of Goethe for the library in Frankfurt; two statues of the Emperor Francis I of Austria, one made with the assistance of Manfredoni, for Goritz, and another, unassisted, for the Hofburg in Vienna.
