 The drawn reconstructions of the painterly decorations of ancient villas he created in Athens inspired his later designs for the painted decorations in Dresden and Vienna.His 1834 publication "Vorläufige Bemerkungen über bemalte Architectur und Plastik bei den Alten" ("Preliminary Remarks on Polychrome Architecture and Sculpture in Antiquity"), in which he took a strong position in favor of polychromy - supported by his investigation of pigments on the Trajan's column in Rome - brought him sudden recognition in architectural and aesthetic circles across Europe .On September 30, 1834 Semper obtained a post as Professor of Architecture at the Königlichen Akademie der bildenden Künste (today called the Hochschule) in Dresden thanks largely to the efforts and support of his former teacher Franz Christian Gau and swore an oath of allegiance to the King (formerly Elector) of Saxony, Anthony Clement.
