Here then (belove reader) thou hast this work devided into two treatises, the first is the said introduction and reasoning, for investigation of the true sense of every cheife Theological tearme and date contained in the Revelation, whereby, not onely is it opened, explained and interpreted, but also that same explanation and interpretation is proved, confirmed and demonstrated, by evidente proofe and coherence of scriptures, agreeable with the event of histories. The seconde is, the principall treatise, in which the whole Apocalyps, Chapter by chapter, Verse by verse, and Sentence by sentence, is both Paraphrastically expounded and Historically applyed. ...And because this whole work of Revelation concerneth most the discoverie of the Antichristian and Papisticall kingdome, I have therefore (for removing of all suspition) in al histories and prophane matters, taken my authorities and cited my places either out of Ethnick auctors, or then papistical writers, whose testimonies by no reason can be refuted against themselves. But in matters of divinitie, doctrine & interpretation of mysteries (leaving all opinions of men) I take me onely to the interpretation and discoverie thereof, by coherence of scripture, and godly reasons following thereupon; which also not only no Papist, but even no Christian may justly refuse. And forasmuch as our scripturs herein are of two fortes, the one our ordinary text, the other extraordinary citations; In our ordinary text, I follow not altogether the vulgar English translation, but the best learned in the Greek tong, so that (for satisfying the Papists) I differ nothing from their vulgar text of S. Jerome, as they cal it, except is such places, where I prove by good reasons, that hee differeth from the Original Greek. In the extraordinary texts of other scriptures cited by me, I followe ever Jeromes latine translation, where any controverse stands betwixt us and the Papists, and that moveth me in divers places to insert his very latine text, for their cause, with the just English thereof, for supply of the unlearned.

In my tender years and bairn-age, at schools, having on the one part contracted a loving familiaritie with a certain gentleman a papist, and on the other part being attentive to the sermons of that worthy man of God, Maister Christopher Goodman, teaching upon the Apocalyps, I was moved in admiration against the blindness of papists that could not most evidentlie see their seven hilled Citie of Rome, painted out there so lively by Saint John, as the Mother of all Spiritual Whoredome: that not onlie bursted I oute in continuall reasoning against my said familiar, but also from thence forth I determined with myself by the assistance of God's spirit to employ my study and diligence to search out the remanent mysteries of that holy booke (as to this houre praised be the Lord I have bin doing at all such times as convenientlie I might have occasion) &c.

Therefore, Sir, let it be your Majesty's continuall study (as called and charged thereunto by God) to reforme the universall enormities of your country, and first (taking example of the princely prophet David) to begin at your Majesty's owne house, familie and court, and purge the same of all suspicion of Papists and Atheists and Newtrals, whereof this Revelation foretelleth that the number shall greatly increase in these latter daies. For shall any Prince be able to be one of the destroyers of that great seate, and a purger of the world from Antichristianisme, who purgeth not his owne countrie? Shall he purge his whole countrie who purgeth not his owne house? Or shall he purge his house, who is not purged himself by private meditations with his God?
