Decoration

11. The Sistine Chapel is a high rectangular brick building
The Sistine Chapel is a high rectangular brick building. The internal spaces are divided into three storeys. The building had six tall arched windows down each side and two at a either end. Several of these have been blocked. Above the vault rises a third storey with wardrooms for guards.
At this level was constructed an open projecting gangway wich encirclled the building supported on an arcade springing from the walls. The gangway has been roofed as it was a continual source of water penetration to the vault of the Chapel. The building is roofed with pantile tiles. Subsidence and cracking of masonry such as must also have affected the Cappella Maggiore has necessitated the building of very large buttresses to brace the exterior walls. The accretion of other buildings has further altered the exterior appearance of the Chapel.

12. Clearly defined proportions were a feature of Renaissance architecture and reflected the growing interest in the Classical heritage of Rome. The pavement is in opus alexandrinum, a decorative style using marble and coloured stone. The screen or transenna in marble by Mino da Fiesole, Andrea Bregno and Giovanni Dalmata divides the chapel in two parts. The sculptors of the transenna also provided the cantoria or projecting choir gallery.

13. The pictorial decoration of the Sistine Chapel comprises frescoes and a set of tapestries. The lower is decorated with frescoed wall hangings in silver and gold.
The central tier of the walls has two cycles of paintings, which complement each other, The Life of Moses and The Life of Christ executed by Ghirlandaio,Botticelli,Perugino and Cosimo Rosselli.
Raffaello design a series of tapestries. The depict the lives of the two leaders among the Apostles who established the Christian church in Rome, Saints Peter and Paul.
The wall paintings were executed by pemier painters: Perugino,Botticelli,Ghirlandaio,Rossellini. The subjects were historical religious themes.

14. Around the arched tops of the windows are areas known as the lunettes which contain the Ancestors of Christ,painted by Michelangelo as part of the scheme for the ceiling. The ceiling painted by Michelangelo has a series of nine paintings showing God’s creation of the World,God’s relationship with Mankind and Makind’s fall from God’s Grace. On the large pendentives are painted twelve Biblical and Classical men and women.

15. Then Langdon and Vittoria go to Santa Maria della Vittoria and here they found another dead cardinal’s body. This time branded by the ambirgam of fire. The murder is still there and he captures Vittoria.

16. Langdon understand that the last science’s altar is at Navona Square but he cant prevent the klilling of the last cardinal, branded by the ambigram of water. Afterwards Langdon saves Victoria and, kills the murder and together they discover the Illuminati plan.

17. The books ends with Langdon and Vittoria that go to the Camerlengo to save him but at the end they understand that he’s Giano, the Illuminati’s leader, and that he organized this plan to obtain fame and become Pope.

18. Surely the author choose Saint Peter as a Science’s Altar because it ranks second among the seven major Basilicas of Rome. Possibly the largest church building in christianity it’s full of statues, frescoes and beautiful architectural elements.

20. Construction was begun on the order of the Roman emperor Costantine I between 326 an 333, and took about 30 years to complete. Papal coronations began to be held here, and in 800, Charlemagne was crowned emperor of the Holy Roman Empire. At first Pope Julius II had every intention of preserving the old building, but his attention soon turned toward tearing it down and building a new structure. Many people of the time were shocked by the proposal but in the end, the design of the new basilica attempted to reconsacrate these remains as much as possible. The original altar was preserved in the new structure which would house it.
