BIBIENA (BIBBIENA), GALLI DA, a family of Italian artists of the 17th and 18th centuries, who took their name from the birthplace of their progenitor, Giovanni Maria Galli (1625-65) born at Bibiena near Bologna. He was a painter, a pupil of Fran cesco Albani. He first laid the foundations of an artistry which was carried on by his descendants, who devoted themselves to scenic work for the theatre. Employing freely the highly ornate style of the Italian Late Baroque architecture and sculpture, the various members of the family produced a series of designs which are amazing for their splendour and spacious proportions. Bold per spective is called into the service of scenic staging. The work of the family was carried beyond the confines of Italy by members who were attached to the imperial court of Vienna and to other courts as architects and designers of theatrical festivities and court functions.
