But the Christians, both Portuguese and Canarians, followed them up with such zeal that just as the first began to enter into the valley, ours were already nigh unto them, and so all together they entered the valley, in such a way that the shepherds were obliged to take shelter among an expanse of rocky crags, the roughness of which was a marvellous thing; but much more marvellous was the ease with which the Canarians of that island made their way among those rocks, as though in sucking the milk from their mothers' breasts, they had commenced to walk in those places. And as the Psylli and Marmaridae,[BP] who live beyond the Libyan desert, know their sons to be sprung from their own bodies if straightway in their first boyhood they handle without fear the great poisons of that desert as they are offered to them by their fathers; so the Canarians of this island consider that their sons, if they are not born with this agility, have been generated by some wicked adultery. [Footnote BP: The text has "Sillos ou Marmorios."] But what about our countrymen, desirous to follow after them, for although they saw the roughness of the ground, yet they did not desist from pursuing them; and there a youth of noble heart, in running over those rocks, slipped from a very large and rough crag, and falling down, died. And think not that this misfortune happened only to that native of our realm, for many Canarians fell in the same way and died: for although Nature from old time had given them to walk among those rocky hills, yet on account of the haste of their enemies, whom they perceived to be near them, and deeming that to be their last remedy, where the crags were roughest, thither with the better will they made their way, thinking that their foes would fear to pursue them.
