Or if he sailed anything near the shore, yet he, being ignorant,
might be deceived by the doubling of many points and capes, and by
the trending of the land, albeit he kept continually along the
shore.

And further, it might be that the poor fisherman through simplicity
thought that there was nothing that way but sea, because he saw mine
land, which proof (under correction) giveth small assurance of a
navigable sea by the north-east to go round about the world, for
that he judged by the eye only, seeing we in this clear air do
account twenty miles a ken at sea.

His second reason is, that there was an unicorn's horn found upon
the coast of Tartary, which could not come (said he) thither by any
