Vatican City
The name was first used in the Lateran Treaty, signed on 11 February 1929, which established the modern city-state. The name is taken from Vatican Hill, the geographic location of the state. "Vatican" is derived from the name of an Etruscan settlement, "Vatica" or "Vaticum" meaning garden, located in the general area the Romans called "vaticanus ager", "Vatican territory".
Vatican Library
In 1451, bibliophile Pope Nicholas V sought to establish a public library at the Vatican, in part to re-establish Rome as a destination for scholarship. Nicholas combined some 350 Greek, Latin and Hebrew codices inherited from his predecessors with his own collection and extensive acquisitions, among them manuscripts from the imperial Library of Constantinople. Pope Nicholas also expanded his collection by employing Italian and Byzantine scholars to translate the Greek classics into Latin for his library. The knowledgeable Pope already encouraged the inclusion of pagan classics. Nicolas was important in saving many of the Greek works and writings during this time period that he had collected while traveling and acquired from others.
