(French, from Breton tolmen "hole of stone") A megalithic (large-stone) tomb with one large flat stone laid on several upright stones. Dolmens were usually originally covered by an earthen hill or barrow.
A large boulder resting, typically, on three smaller stones. These boulders can range from one ton to many ton monstrosities. These constructions are manmade, but who or when is unclear. A second style of dolman is glacier created, and is more correctly called a perched rock to differentiate it from a human construction. Both, however, often have colored stones placed underneath them like an offering or donation.
Any Neolithic monument consisting of a large, flat stone supported by two or more rocks (like a table). It used to be believed that such monuments were altars for human sacrifice or cannibal feasts. With the advent of modern day grave-robbing and archaeology, dolmen were discovered inside of burial mounds with the supposed meal underneath the table. Science concluded that they formed a vault and supposed that exposed versions were either incomplete tombs or windblown remains. Cromlechs and dolmen are the same thing, but since French is considered more chíc than Welsh, the latter term is preferred by the scientific community these days.
Dolmen is a french TV miniseries, consisting of six 90 minutes-long episodes, and starring Ingrid Chauvin. It was written by Nicole Jamet and Marie-Anne Le Pezennec, and broadcast for the first time between June 13 and July 18 2005 on TF1.
