Note 200 — Chapter III · THE MONASTIC CHURCH IN IONA.

Lib. Hymn., part ii. p. 220. Mr. Hennessy suggests that the syllable Blath here stands for Blad, a portion, fragment, partition, division, which is also written Blod, Blag, Blog, and by O’Clery in his glossary Bladh, who explains it by rann no cuid do ni, a portion, or share, of a thing. That Moel, or Mael, when applied to a stone means a flat-surfaced stone, which exactly answers the description of the boulder. He thinks Moelblath may be fairly rendered ‘the flat stone of division.’
