Introduction
Vatican City (/ˈvætɪkən/ (
listen)), officially Vatican City State (Italian: Stato della Città del Vaticano; Latin: Status Civitatis Vaticanae), is an independent city-state enclaved within Rome, Italy. Established with the Lateran Treaty (1929), it is distinct from yet under "full ownership, exclusive dominion, and sovereign authority and jurisdiction" of the Holy See (Latin: Sancta Sedes). With an area of 44 hectares (110 acres), and a population of about 1,000, it is the smallest state in the world by both area and population.
The Vatican City is an ecclesiastical or sacerdotal-monarchical state (a type of theocracy) ruled by the pope who is, religiously speaking, the bishop of Rome and head of the Catholic Church. The highest state functionaries are all Catholic clergy of various national origins. Since the return of the popes from Avignon in 1377, they have generally resided at the Apostolic Palace within what is now Vatican City, although at times residing instead in the Quirinal Palace in Rome or elsewhere.

The heart of the telescope is an f/1.0 honeycombed construction, borosilicate primary mirror. The mirror was manufactured at The University of Arizona's Steward Observatory Mirror Laboratory[1], which pioneered both the spin-casting and the stressed-lap polishing techniques which are being used for telescope mirrors that include the 6.5 meter aperture MMT and Magellan telescopes and the two 8.4 meter mirrors of the Large Binocular Telescope. The VATT's mirror is unusually 'fast', f/1, which means that its focal distance is equal to its diameter. Because it has such a short focal length, a Gregorian design could be employed which uses a concave secondary mirror at a point beyond the primary focus; this allows unusually sharp focusing across the field of view.
The unusual optical design and novel mirror fabrication techniques mean that both the primary and secondary mirrors are among the most exact surfaces ever made for a ground-based telescope. In addition, the skies above Mount Graham are among the most clear, steady, and dark in the continental North America. Seeing of better than one arc-second even without adaptive optics can be achieved on a regular basis.

The restoration of the frescoes of the Sistine Chapel was one of the most significant art restorations of the 20th century. The Sistine Chapel was built by Pope Sixtus IV within the Vatican immediately to the north of St. Peter's Basilica and completed in about 1481. Its walls were decorated by a number of Renaissance painters who were among the most highly regarded artists of late 15th century Italy, including Ghirlandaio, Perugino, and Botticelli. The Chapel was further enhanced under Pope Julius II by the painting of the ceiling by Michelangelo between 1508 and 1512 and by the painting of the Last Judgment, commissioned by Pope Clement VII and completed in 1541, again by Michelangelo. The tapestries on the lowest tier, today best known from the Raphael Cartoons (painted designs) of 1515–16, completed the ensemble.
Together the paintings make up the greatest pictorial scheme of the Renaissance. Individually, some of Michelangelo's paintings on the ceiling are among the most notable works of western art ever created. The frescoes of the Sistine Chapel and in particular the ceiling and accompanying lunettes by Michelangelo have been subject to a number of restorations, the most recent taking place between 1980 and 1994. This most recent restoration had a profound effect on art lovers and historians, as colours and details that had not been seen for centuries were revealed.
