Italo-Swiss family who designed operatic and theatrical stage-sets for the Electoral Courts of Mannheim and Munich and the Imperial Court of Vienna from C17 to C19. Some Quaglios were also architects. Lorenzo (1730–1805) designed some theatres, including the reconstruction of the Schlosstheater (1768) and the building of the Nationaltheater (1777–8), both in Mannheim, as well as (probably) Schloss Wain, Laupheim, Württemberg (1780), and the Rathaus (Town Hall), Lauingen (1783–90). Angelo (1784–1815) introduced Neo-Gothic designs, while Simon (1795–1878) produced a series of very fine Egyptian Revival sets for the 1818 production of Mozart's Die Zauberflöte (The Magic Flute) at Munich, equal in authority to Schinkel's 1816 designs for Berlin. Giulio (1764–1801) decorated the Court Theatre, Dessau (1798), and Domenico (1787–1837) was a pioneer of the Gothic Revival, publishing some views of old Munich in 1812 and Denkwürdige Gebäude des Mittelalters (Memorable Buildings of the Middle Ages), an important work on German medieval art (1818–23). He rebuilt Schloss Hohenschwangau, near Füssen, Bavaria, in a charming Neo-Gothic style (1832–7). Giovanni Maria, also called Johann Maria von (1772–1813) published Praktische Anleitung zur Perspektive mit Anwendung auf die Baukunst (Practical Guidance on Perspective with Application to Architecture—1811, 1823).
