Q: Question: What was the location of Christina and Ferdinando's wedding? Passage:The intermedio (also intromessa, introdutto, tramessa, tramezzo, intermezzo), in the Italian Renaissance, was a theatrical performance or spectacle with music and often dance, which was performed between the acts of a play to celebrate special occasions in Italian courts. It was one of the important predecessors to opera, and an influence on other forms like the English court masque. Weddings in ruling families and similar state occasions were the usual occasion for the most lavish intermedi, in cities such as Florence and Ferrara. Some of the best documentation of intermedi comes from weddings of the House of Medici, in particular the 1589 Medici wedding (between Christina of Lorraine and Ferdinando I de' Medici, Grand Duke of Tuscany), which featured what was undoubtedly both the most spectacular set of intermedi, and the best known, thanks to no fewer than 18 contemporary published festival books and sets of prints that were financed by the Grand Duke.
