There are many interesting myths associated with the Morbihan Megaliths. Some of the myths, according to the website, are easily tied with historical events that cause a trend of myths associated with the megaliths. The myth of Saint-Cornely is a prime example of such a myth; branching from the historical Council of Trent. This council, which began in 1545, is considered one, if not the most influential ecumenical councils in the church’s history. While instigating many changes involving reaffirmation of Catholic doctrines, identifying and condemning principles of Protestantism, and reforming change in that sought to bring an end to church corruption such as paid indulgences, the council also in a sense reaffirmed some archaic practices such as the reverence of saints and pilgrimages. This support of the veneration of saints and of pilgrimages may have caused the growth of the Saint-Cornely myth, which is the most popular of the myths according to the website.
One of the more interesting myths associated with the Morbihan Megaliths is the myth that dwarves are often associated with the construction of and their appearance at the megaliths. It is hard to say how a myth of dwarves would have begun. The idea of dwarves almost certainly comes from other ancient lore from that region that had earlier beginnings than the megalith dwarves. Interestingly, I once watched a documentary that sought a way to theorize the establishment of mythical creatures such as dwarves and this documentary theorized that dwarves were in actuality pygmy groups of that region. It was also hypothesized that ancient human remains gave the idea of dwarves because the average height of ancient humans was noticeable shorter than the modern average.
Although the founding of these myths are esoteric and their lore are somewhat outlandish, they give the megaliths a type of mysterious charm that is often characteristic to many great art pieces of that time. It is interesting to note that religious connotations are often assigned to ancient pieces of art. The idea of creating art for the sake of contributing to the art community had not been imagined yet and therefore these religious conjectures as to the purpose of these ancient art pieces such as the megaliths or the Lascaux caves are merited. Today it is interesting to note a stark contrast between the art community and the religious community, but their roots are much more integral to one another than most people realize.
