The relief It is made up of everything that excels from a flat surface or that the modifies. The concept is often used to refer to elevations and the depressions found in our planet.
In this sense, the terrestrial relief includes both the forms that are noticed surface level as well as those that involve accidents in the seabed. The plains, the valleys, the mountains, the saws, the hills, the moutains and the cannons they are part of the relief.
There are various processes that determine the relief of a region. Most are geological processes, whether internal or external, such as earthquakes, volcanic activity and erosion caused by water and wind. Also the action of human being It can generate changes in the relief: this is what happens, for example, when man uses explosives to modify the appearance of a mountain and open a road or to take advantage of its natural resources through mining.
In the field of art and from design, is known as relief to the protuberance or prominence that stands out in some type of work or creation. A box with relief It is not flat, but has different layers or appliqués sticking out of the canvas.
Within the artistic field, we can establish that there are various types of relief, among which the following stand out in a special way:
-Hueco relief, in which it is committed to represent the figures through what is the incision in their contours.
-Sunken relief, which is the one that is undertaken when the figure to be represented is carved in the same block that serves as a support. Examples of this type can be found in the Egyptian temple of Kom Ombo.
There are also those known as low relief, medium relief and high relief, which establish that the represented figures protrude from the background less than half, half or more than half respectively. Among the most significant examples are the bas-reliefs in the aforementioned temple, the existing half-reliefs in the Dendera necropolis and the high-reliefs of the spectacular Egyptian sculptural group known as the Triad of Menkaure.
In addition to all those exhibited, we cannot forget that, throughout the history of art, reliefs of great beauty and spectacularity have been made, which today are key pieces of this discipline. In particular, those of the archaeological site of Chichén Itzá, in the Yucatan Peninsula (Mexico); the Elgin Marbles of the Parthenon; the Hell Gate made by Auguste Rodin at the end of the 19th century; the Door of Paradise that Lorenzo Ghiberti carried out in the 15th century for the Baptistery of Florence; those of Trajan’s Column …
Finally, the idea of relief can be linked to the transcendence or importance of a person or an event: “He is an internationally renowned player who will contribute a lot to our team”, “No one can deny the importance of these events that, without a doubt, will mark the history of this town”.
