The reason alleged for proof of the contrary may be disposed after this manner: And first, it may be called in controversy, whether any current continually be forced by the motion of primum mobile, round about the world or no; for learned men do diversely handle that question. The natural course of all waters is downward, wherefore of congruence they fall that way where they find the earth most low and deep: in respect whereof, it was erst said, the seas do strike from the northern lands southerly. Violently the seas are tossed and troubled divers ways with the winds, increased and diminished by the course of the moon, hoisted up and down through the sundry operations of the sun and the stars: finally, some be of opinion that the seas be carried in part violently about the world, after the daily motion of the highest movable heaven, in like manner as the elements of air and fire, with the rest of the heavenly spheres, are from the east unto the west. And this they do call their eastern current, or Levant stream. Some such current may not be denied to be of great force in the hot zone, for the nearness thereof unto the centre of the sun, and blustering eastern winds violently driving the seas westward; howbeit in the temperate climes the sun being farther off, and the winds more diverse, blowing as much from the north, the west, and south, as from the east, this rule doth not effectually withhold us from travelling eastwards, neither be we kept ever back by the aforesaid Levant winds and stream. But in Magellan strait we are violently driven back westward, ergo through the north-western strait or Anian frith shall we not be able to return eastward: it followeth not. The first, for that the north-western strait hath more sea room at the least by one hundred English miles than Magellan's strait hath, the only want whereof causeth all narrow passages generally to be most violent. So would I say in the Anian Gulf, if it were so narrow as Don Diego and Zalterius have painted it out, any return that way to be full of difficulties, in respect of such straitness thereof, not for the nearness of the sun or eastern winds, violently forcing that way any Levant stream; but in that place there is more sea room by many degrees, if the cards of Cabot and Gemma Frisius, and that which Tramezine imprinted, be true.
