Answer: The power of the Popes
Explanation: During the Renaissance, especially in its late period, the Pope's institution began to take on more and more political and diplomatic features. Thus, apart from the spiritual centre and spiritual leadership of the Church, the independent Papal State was also a modern state of that time, therefore secularist, with all political influences and interests. The position of the Pope during this period was so secularised that no Pope from that period was proclaimed Blessed, therefore canonised for his spiritual and ascetic way of life.
Of course, in the spirit of the time such as the Renaissance, the Pope wanted, regardless of whoever it was, to favour his Papal State, the Vatican in every, therefore political, influential and artistic sense, since that endowment and donation of culture and art was one of ways of create an influence. Such influence and invitation for artists to contribute to the development of culture, art and architecture in Rome was widely accepted and many moved to Rome, gaining a great deal of freedom of expression which made it the centre of artistic expression and production.
