The Decorative Arts Department is a relatively new section of the Vatican Museums. In fact, this department was created in 1999 by Pope John Paul II who wished to place the Vatican Museum Library under the jurisdiction of the Vatican Museums. However, the origins of the rooms that form the Vatican Museums Library reach back to 1756, during the papacy of Benedict XIV when the Christian Museum (which includes three rooms: Christian Museum, Room of the Tributes and Room of The Tributes to Pius IX) was the first to be formally addressed as the Vatican Museums (Costitutio Optimarum Artium). The objects on display in the Christian Museum rooms were intended for scholars and priests who, while studying the origins of Christianity in the Library, could easily compare and complete their readings with the actual objects. Professor Guido Cornini is the curator of this section, and he is assisted by Dr. Claudia Lega. The Decorative Arts Department takes care of the Christian Museum, the Profane Museum and the Museum of the Gifts. Indeed, these three Museums form part of the Gallery of the Ancient Library (or Vatican Library Museum), a gallery our Patrons are accustomed to walking through when they visit the Vatican Museums as it is also the exit for the visitors leaving the Sistine Chapel. Since October 2008, this Department has also acquired micro mosaics, liturgical vestments, as well as medieval and modern ceramics of the Vatican Museums.
