Father António Vieira wrote the History of the Future with the purpose of explaining how Portugal would become the nation from which the Fifth Empire would be born, and how this Empire would be a Spiritual one. The analysis of several biblical texts, such as prophecies included in the Book of Daniel (Old Testament), as well as the Book of Revelation (New Testament), in addition to other religious texts, served as basis for justification that Portugal would be the leader of this new empire. Vieira intended to seek the past for the explanation and justification of the inevitable future of the Lusitanian people. These ideas, which were generalized under the philosophy of Sebastianism, already pointed out by Camões, the Portuguese poet, have been absorbed by several authors.
According to the History of the Future, the explanations of the prophecies are for those who can understand them, for they are enclosed in mysterious metaphors. The reading of the enigmatic Book of Daniel opens the way to the most diverse interpretations. Thus, for Vieira, what was "hidden" should become apparent to those who know how to interpret the prophecy: Ut ex invisibilibus, visibilia fiant (for invisible things to be made visible).
This composition was inspired by this work of Vieira. Perhaps, from the point of view of the temporal fulfillment of the prophecies, the Fifth Empire will not be born of a single nation, but of all mankind. The biblical apocalypse prophesies a time of peace, tolerance and faith. And perhaps it is within each of us to seek and strive to build this time.
The musical notes that I used to compose this work are the first 4 notes of the Portuguese National Anthem (E-C#-A-F#). But as Vieira explains in his prophetic thoughts, they are initially "invisible", and only with the progressing of the piece they become apparent for those who listen attentively and seek to understand.
"The Apostle Paul says that he accommodated God and divided the centuries according to the decrees of his Word, so that invisible things were made visible: Fide intelligimus aptata, saecula verb Dei, ut ex invisibilibus, visibilia fiant; and the people who inhabited it, were ignored and invisible for so many centuries, and then came a time to be discovered and visible; and as this veil was unveiled, the lands and people which the Prophets had spoken of, were discovered and manifested, and so the secrets and mysteries of their prophecies were understood and discovered." (António Vieira: History of the Future, Volume I, Chapter 12).
