And from the tribal homeland: "I went to the huts of some of the savages that were there, who told me of the great misfortunes of our people who were drowned at that place and showed me many jewels and valuables of theirs, which distressed me greatly" - Fancisco Cuellar, describing the northern Ireland coast in 1589.
