 As for the Fifth Monarchists later in England and other authors, although with some differences, Vieira, with an elaborate exegesis based on his vast knowledge of the Bible, believed that the timing was significant because the calendar year 1666 was approaching.The number 666 had been identified in the Book of Revelation with the ultimate human despot to rule the world, but who would be replaced by the second coming of the Messiah; this added to his belief that the Fifth Monarchy was possibly about to begin.Gonçalo Anes Bandarra, the 16th century shoemaker turned prophet whom interpreters credit with foretelling accurately the coming of a period of 60 years when Portugal was under Spanish rule, the subsequent 1640 revolution and liberation under king John IV ("after thirty scissors") and the reigns of Afonso VI, Peter II and John V, was an inspired prophet to António Vieira and the Sebastianists of his time.
