About Petroglyphs

worth mentioning that the area of \u200b\u200bmaximum concentration of rock engravings occur in the western region of Galicia. It is a geographical area more appropriate corresponds to the greatest variety of types and the most successful aesthetic expressions.

granite erosion has decisively altered the traces in the preparation of the petroglyphs, but by studying the shape of their grooves, may be regarded as possibly the most widespread system for them was the percussion with a pointed stone tools. As for the thematic repertoire, say it is not very varied, and usually has nothing to do with the figurative. There are 2 groups of subjects: the purely geometrical reasons, and naturalists, the latter being understood as a representation of figures in which at least can be identified as beasts or human figures. Here are some varieties theme: -CUPS: hemispheric are holes dug in the rock. Its diameter is not usually go by 5 centimeters. May appear isolated or associated group other topics. -GROUPS: combinations of circles that have many variants. -Zoomorph: the 3 rd of the great rock types represented in the outdoors. Sometimes it is difficult to establish a classification by outlining presented. We have a predominance of the deer, followed by horses and snakes. May appear isolated, other issues related to forming complex compositions. -anthropomorphic human representation is limited and is usually associated with other figures are scenes of hunting or grazing. -IDOLIFORMES: in a very few figures appear idol-cylinder. -ARMS: except for a couple of cases, the rocks where displayed various types of knives, nails at the base and possibly shields, are concentrated in the province of Pontevedra (Galicia, Spain). But we do not know how far we have the existence of various "schools" that have local preference when choosing the topics. It may be simply different times within a tradition. Some researchers related to the archeology of the landscape have raised the petroglyphs can be identified as "signs." Other theories suggest that these petroglyphs might define a territory, ie, could function as territorial markers. The Galician side is presented as one of the most peculiar and rich of his time within both European and global context. Art is a little narrative, which highlights the symbolic nature, which reflects secular and religious aspects of the mentality of the era. Tend to date their beginnings in the late Chalcolithic period, while its full development is built during the Bronze Age (1800-700 BC) and have lasted until the late Iron Age. -PETROGLIFOS PEDRA Ferradura A-(DEER, IDOLS-CYLINDER, swastikas) -DETAIL petroglyphs (CIRCLES, LABERINTOS)
