Sabaudia, and its memories of childhood, is the first stop in a personal and artistic journey taken by the painter Filippo di Sambuy. A journey that takes us from the new fascist city (that was founded in 1934), and constructed by the young rationalist architects according an almost metaphysical system. It is the metaphysics of De Chirico, fascinated by the geometric regularity of the streets and squares of Turin, where he lived in 1911 and where one finds the Hunting Palace of Stupinigi, the symbol of a regal pomp that Sabaudia had lost by then. The journey comes to an end at Castel del Monte, a hunting residence like Stupinigi, but also a metaphysical building par excellence; conceived by Emperor Frederick II to have octagonal floors, full of numerical symbology and references of Jerusalem and the East. Flags, armorial bearings, stars and rose windows are painted or represented in relief by Filippo di Sambuy to accompany accurate cross-references and precise symbology in this historical, artistic and architectural voyage in the search of lost rites and myths.
