_Cromlech._--As your learned correspondent "Dr. TODD" (No. 20. p. 319.)
queries this word, I think it is very doubtful whether the word was in
use, or not, before the period mentioned (16th century). Dr. Owain Pughe
considered the word "cromlech" (_crwm-llech_, an inclined or flat
stone,) to be merely a popular name, having no reference to the original
purpose of the structure. The only Triadic name that will apply to the
cromlechs, is _maen ketti_ (stone chests, or arks), the raising of which
is described as one of "The three mighty labours of the Isle of
Britain."
