For Columbus had none of the West Islands set foorth vnto him, either in globe or card, neither yet once mentioned of any writer (Plato excepted, and the commentaries vpon the same) from 942 yeeres before Christ, vntill that day. Moreouer, Columbus himselfe had neither seene America nor any other of the Islands about it, neither, vnderstood he of them by the report of any other that had seene them, but only comforted himselfe with this hope, that the land had a beginning where the Sea had an ending: for as touching that which the Spaniards doe write of a Biscaine, which should haue taught him the way thither, it is thought to be imagined of them, to depriue Columbus of his honour, being none of their countrey man, but a stranger borne. And if it were true of the Biscaine, yet did he but roue at the matter, or (at the least) gathered the knowledge of it, by coniectures onely. And albeit myselfe haue not seene this passage nor any part thereof, but am ignorant of it as touching experience (as Columbus was before his attempt made) yet haue I both the report, relation, and authoritie of diuers most credible men, which haue both seene and passed through some and euery part of this discouery, besides sundry reasons for my assurance thereof: all which Columbus wanted. These things considered, and indifferently weighed togither, with the wonderfull commodities which this discouery may bring, especially to this realme of England: I must needes conclude with learned Baptista Ramusius, and diuers other learned men, who said, that this discouery hath bene reserued for some noble prince or worthie man, thereby to make himselfe rich, and the world happie: desiring you to accept in good part this briefe and simple discourse, written in haste, which if I may perceiue that it shall not sufficiently satisfie you in this behalfe, I will then impart vnto you a large discourse, which I haue written onely of this discouery. And further, because it sufficeth not only to know that such a thing there is, without abilitie to performe the same, I wil at at leasure make you partaker of another simple discourse of nauigation, wherein I haue not a little trauelled, to make my selfe as sufficient to bring these things to effect, as I haue bene readie to offer my selfe therein. And therein I haue deuised to amend the errors of vsuall sea cards, whose common fault is to make the degrees of longitude in euery latitude of one like bignesse. And haue also deuised therein a Spherical instrument, with a compasse of variation for the perfect knowing of the longitude. And a precise order to pricke the sea card, together with certaine infallible rules for the shortning of any discouery, to know at the first entring of any fret whether it lie open to the Ocean more wayes then one, how farre soeuer the sea stretcheth itself into the land.
