did. During these intermediate times, popes strove to make Rome the capital of Christendom while projecting it through art, architecture, and literature as the center of a Golden Age of unity, order, and peace. Professor Frederick J. McGinness described Rome as essential in understanding the legacy the Church and its representatives encapsulated best by The Eternal City:
No other city in Europe matches Rome in its traditions, history, legacies, and influence in the Western world. Rome in the Renaissance under the papacy not only acted as guardian and transmitter of these elements stemming from the Roman Empire but also assumed the role as artificer and interpreter of its myths and meanings for the peoples of Europe from the Middle Ages to modern times... Under the patronage of the popes, whose wealth and income were exceeded only by their ambitions, the city became a cultural center for master architects, sculptors, musicians, painters, and artisans of every kind...In its myth and message, Rome had become the sacred city of the popes, the prime symbol of a triumphant Catholicism, the center of orthodox Christianity, a new Jerusalem.
It is clearly noticeable that the popes of the Italian Renaissance have been subjected by many writers with an overly harsh tone. Pope Julius II, for example, was not only an effective secular leader in military affairs, a deviously effective politician but foremost one of the greatest patron of the Renaissance period and person who also encouraged open criticism from noted humanists. The blossoming of renaissance humanism was made very much possible due to the universality of the institutions of Catholic Church and represented by personalities such as Pope Pius II,

The enterprise of individuals or of small aristocratic bodies has meantime sown the world which we call civilised with some seeds and nuclei of order. There are scattered about a variety of churches, industries, academies, and governments. But the universal order once dreamt of and nominally almost established, the empire of universal peace, all-permeating rational art, and philosophical worship, is mentioned no more. An unformulated conception, the prerational ethics of private privilege and national unity, fills the background of men's minds. It represents feudal traditions rather than the tendency really involved in contemporary industry, science, or philanthropy. Those dark ages, from which our political practice is derived, had a political theory which we should do well to study; for their theory about a universal empire and a Catholic church was in turn the echo of a former age of reason, when a few men conscious of ruling the world had for a moment sought to survey it as a whole and to rule it justly.

Architecture

Christian architecture encompasses a wide range of both secular and religious styles from the foundation of Christianity to the present day, influencing the design and construction of buildings and structures in Christian culture.Fletcher, Banister. ''A History of Architecture'' Buildings were at first adapted from those originally intended for other purposes but, with the rise of distinctively ecclesiastical architecture, church buildings came to influence secular ones which have often imitated religious architecture. In the 20th century, the use of new materials, such as concrete, as well as simpler styles has had its effect upon the design of churches and arguably the flow of influence has been reversed. From the birth of Christianity to the present, the most significant period of transformation for Christian architecture in the west was the Gothic cathedral. In the east,
