Dolmens of the Caucasus Mountains
There are several theories about origin of the word dolmen. One theory suggests that it is of Breton origin. It consists of two roots, taol (table) and maen (rock). In the 17th century, the Breton language was used to name the main megalithic structures: stone circle (crom llech), long stone–menhir (maen-hir), and stone table (taol maen).1
The North Caucasus dolmens are different from what is normally called a dolmen. Nevertheless, in Russia, they are known as dolmens.
