Mermen and mermaids disport themselves on the coasts of Man, but I have to confess that I have made no careful inquiry into what is related about them; and my information about the giants of the island is equally scanty. To confess the truth, I do not recollect hearing of more than one giant, but that was a giant: I have seen the marks of his huge hands impressed on the top of two massive monoliths. They stand in a field at Balla Keeill Pherick, on the way down from the Sloc to Colby. I was told there were originally five of these stones standing in a circle, all of them marked in the same way by the same giant as he hurled them down there from where he stood, miles away on the top of the mountain called Cronk yn Irree Laa. Here I may mention that the Manx word for a giant is foawr, in which a vowel-flanked m has been spirited away, as shown by the modern Irish spelling, fomhor. This, in the plural in old Irish, appears as the name of the Fomori, so well known in Irish legend, which, however, does not always represent them as giants, but rather as monsters. I have been in the habit of explaining the word as meaning submarini; but no more are they invariably connected with the sea. So another etymology recommends itself, namely, one which comes from Dr. Whitley Stokes, and makes the mor in fomori to be of the same origin as the mare in the English nightmare, French cauchemar, German mahr, 'an elf,' and cognate words. I may mention that with the Fomori of mythic origin have doubtless been confounded and identified certain invaders of Ireland, especially the Dumnonians from the country between Galloway and the mouth of the Clyde, some of whom may be inferred to have coasted the north of Ireland and landed in the west, for example in Erris, the north-west of Mayo, called after them Irrus (or Erris) Domnann.
