Casa degli Omenoni is a historic palace of Milan, northern Italy, located in the eponymous street of Via degli Omenoni (number 3). It was designed by sculptor Leone Leoni for himself; he both lived and worked there. It owes its name to the eight atlantes decorating its facade, termed "omenoni" ("big men" in Milanese), which were sculpted by Antonio Abondio, most probably on a design by Leoni. Lions (a reference to the "Leoni" family) are a recurring theme of its decorations; in particular, a large relief placed under the cornice depicts two lions tearing a satyr into pieces. The overall style of the palace and the decorations have been noted to include several references to the art of Michelangelo. The internal courtyard, modified in 1929 by Piero Portaluppi, has a colonnade with metopes and triglyphs.
Artist and historian Giorgio Vasari expressed his admiration for the palace, stating that it was pieno [...] di capricciose invenzioni ("full of capricious inventions"). At the time, the palace also housed a notable collection of art works and antiquities, which has been dispersed over time. According to an inventory dating back to 1615, it had paintings by Titian, Parmigianino, and Michelangelo; the inventory also mentions a book of drawings by Leonardo da Vinci, which scholars identify with the Codex Atlanticus now preserved in the Biblioteca Ambrosiana.
