[Sidenote: The answer or resolution.] Whereunto I answered, that the Tartarians were a barbarous people, and vtterly ignorant in the Arte of Nauigation, not knowing the vse of the Sea Card, Compasse or Starre, which he confessed to be true: and therefore they could not (said I) certainly know the Southeast from the Northeast, in a wide sea, and a place vnknowen from the sight of the land. Or if he sailed any thing neere the shore, yet he (being ignorant) might be deceiued by the doubling of many points and Capes, and by the trending of the land, albeit he kept continually alongst the shore. [Sidenote: Visus nonnunquam fallitur in suo obíecto.] And further, it might be that the poore Fishermen through simplicitie thought that there was nothing that way but sea, because he saw no land: which proofe (vnder correction) giueth small assurance of a Nauigable sea by the Northeast, to goe round about the world, For that be iudged by the eye onely, seeing we in this our cleare aire doe account twentie miles a ken at Sea. [Sidenote: The second reason or allegation.] His second reason is, that there was an Vnicornes horne found vpon the coast of Tartaria, which could not come (said he) thither by any other meanes then with the tides, through some fret in the Northeast of Mare Glaciale, there being no Vnicorne in any part of Asia, sauing in India and Cataia: which reason (in my simple iudgement) forceth as litle. [Sidenote: The answer or resolution.] First, it is doubtfull whether those barbarous Tartarians do know an Vnicornes horne, yea, or no: and if it were one, yet it is not credible that the Sea could haue driuen it so farre, being of such nature that it will not swimme. Also the tides running too and fro, would haue driuen it as farre backe with the ebbe, as it brought it forward with the flood. There is also a beast called Asinus Indicus (whose horne most like it was) which hath but one horne like an Vnicorne in his forehead, whereof there is great plenty in all the North parts thereunto adioyning, as in Lappia, Noruegia, Finmarke, &c. as Iacobus Zieglerus writeth in his historie of Scondia. And as Albertus saieth, there is a fish which hath but one horne in his forehead like to an Vnicorne, and therefore it seemeth very doubtfull both from whence it came, and whether it were an Vnicornes horne, yea, or no. [Sidenote: The third and last reason or assertion.] His third and last reason was, that there came a continuall streame or currant through Mare Glaciale, of such swiftnesse (as a Colmax told him) that if you cast any thing therein, it would presently be carried out of sight towards the West.
