"Later on, they made words; they placed stone upon stone, they coupled those syllables of granite, and attempted some combinations. The Celtic dolmen and cromlech, the Etruscan tumulus, the Hebrew galgal, are words. Some, especially the tumulus, are proper names. Sometimes even, when men had a great deal of stone, and a vast plain, they wrote a phrase. The immense pile of Karnac is a complete sentence."
