GavinW, I don't think so, in this case, I think it was used to say "huge" (dimensions).
Fair enough, your call, but if you use this adjective in connection with stone blocks, there are 2 possibilities:
1) it is a literal, technical reference, and, pace the Wiki page, this former archeologist, for one, can confirm that it's a common adjective used to describe other ancient building techniques, including Etruscan and Andean masonry, not just ancient Greek; or:
2) it's a figurative, non-technical reference just meaning "huge" (as you and others believe).
Only you can know, because you have the (full) context, and you haven't shared it with us yet! ;-)
