Kainum’s Stone

Unfortunately, in a study of these remains (Bodmin Moor Stone Circles and Cairns) there can be no certainty concerning their designers - other than an overwhelming mass of substantial evidence - unless some definitive artefact, or intelligible record, should be unearthed. In Cornwall, there seems little likelihood of this, unless some inspired archaeologist should stumble on a find equivalent to that of Kainum, son of Arpachshad - a grandson of Noah:
[JUB VIII:3-4 VB] And he found a writing which former generations had carved upon a rock, and he read what was thereon, and he transcribed (it) and sinned [sic] owing to it, for it contained the teaching of the Watchers in accordance with which they used to observe the omens of the Sun and Moon and Stars in all the signs of heaven.

And he wrote it down and said nothing about it,' for he was afraid to speak to Noah about it lest he should be angry with him on account of it.
