The term monumental sculpture is often used in "art history and "criticism, but not always consistently. It combines two concepts, one of function, and one of size, and may include an element of a third more subjective concept. It is often used for all sculptures that are large. Human figures that are perhaps half life-size or above would usually be considered monumental in this sense by art historians, although in "contemporary art a rather larger overall scale is implied. Monumental sculpture is therefore distinguished from small portable "figurines, small metal or "ivory "reliefs, "diptychs and the like.
It is also used of sculpture that is architectural in function, especially if used to create or form part of a "monument of some sort, and therefore capitals and reliefs attached to buildings will be included, even if small in size. Typical functions of monuments are as grave markers, "tomb monuments or "memorials, and expressions of the power of a ruler or community, to which churches and so religious statues are added by convention, although in some contexts monumental sculpture may specifically mean just "funerary sculpture for "church monuments.
The third concept that may be involved when the term is used is not specific to sculpture, as the other two essentially are. The entry for "Monumental" in "A Dictionary of Art and Artists" by "Peter and Linda Murray describes it as:
"The most overworked word in current art history and criticism. It is intended to convey the idea that a particular work of art, or part of such a work, is grand, noble, elevated in idea, simple in conception and execution, without any excess of virtuousity, and having something of the enduring, stable, and timeless nature of great architecture. ... It is not a synonym for 'large'.
However this does not constitute an accurate or adequate description of the use of the term for sculpture, though many uses of the term that essentially mean either large or "used in a memorial" may involve this concept also, in ways that are hard to separate. For example, when "Meyer Schapiro, after a chapter analysing the carved capitals at "Moissac, says: "in the "tympanum of the south portal [(right)] the sculpture of Moissac becomes truly monumental. It is placed above the level of the eye, and is so large as to dominate the entire entrance. It is a gigantic semi-circular relief ...", size is certainly the dominant part of what he means by the word, and Schapiro's further comments suggest that a lack of "excess of virtuousity" does not form part of what he intends to convey. Nonetheless, parts of the Murray's concept ("grand, noble, elevated in idea") are included in his meaning, although "simple in conception and execution" hardly seems to apply.
The term 'Monumental Sculptures' has acquired various meanings over the years, but these different meanings have not caused much difficulty in classification, as the various interpretations incorporate the changing nature of sculptures through temporal and spacial landscapes in this category. The term may be used differently for different periods in history, with breaks occurring around the "Renaissance and the early 20th century. The ancient and medieval sculpture size is normally taken as the criterion for definition, although smaller architectural sculptures can also be addressed by the term. In the "Early Modern period a specific funerary function may have been meant, but the meaning of size was once again adopted while referring to contemporary sculpture. The relevant chapters in Parts 2-4 of The Oxford History of Western Art are titled as follows: "Monumental Sculpture to c.1300", "Monumental Sculpture 1300–1600", "Free-standing Sculpture c.1600–c.1700", "Forms in Space c.1700–1770", "Sculptures and Publics" (1770–1914).
In "archeology and art history the appearance, and sometimes disappearance, of monumental sculpture (using the size criterion) in a culture, is regarded as of great significance, though tracing the emergence is often complicated by the presumed existence of sculpture in wood and other perishable materials of which no record remains; the "totem pole is an example of a tradition of monumental sculpture in wood that would leave no traces for archaeology. The ability to summon the resources to create monumental sculpture, by transporting usually very heavy materials and arranging for the payment of what are usually regarded as full-time sculptors, is considered a mark of a relatively advanced culture in terms of social organization.
In "Ancient Egypt, the "Great Sphinx of Giza probably dates to the 3rd millennium BC and may be older than the "Pyramids of Egypt. Recent unexpected discoveries of Ancient Chinese "bronze age figures at "Sanxingdui, some more than twice human size, have disturbed many ideas held about early Chinese civilization, since only much smaller bronzes were previously known. Some undoubtedly advanced cultures, such as the "Indus Valley civilization, appear to have had no monumental sculpture at all, though producing very sophisticated figurines and seals. The "Mississippian culture seems to have progressing towards its use, with small stone figures, when it collapsed. Other cultures, such as Ancient Egypt and the "Easter Island culture, seem to have devoted enormous resources to very large-scale monumental sculpture from a very early stage.
There may be a number of reasons why a culture ceases to produce monumental sculpture, . The most common is "societal collapse, as occurred in Europe during the so-called "Dark Ages or the "Classic Maya collapse in "Mesoamerica. Another may be "aniconism, usually religiously motivated, as followed the "Muslim conquests. Both the rise of Christianity (initially) and later the "Protestant Reformation brought a halt to religious monumental sculpture in the regions concerned, and greatly reduced production of any monumental sculpture for several centuries. "Byzantine art, which had largely avoided the societal collapse in the "Western Roman Empire, never resumed the use of monumental figurative sculpture, whether in religious or secular contexts, and was to ban even two-dimensional religious art for a period in the "Byzantine iconoclasm.
"Monumental sculpture" is still used within the stoneworking and funeral trades to cover all forms of grave headstones and other funerary art, regardless of size. In contemporary art, however, it is used to refer to all large sculptures regardless of purpose, and also carries a sense of permanent, solid, objects, rather than the temporary or fragile assemblages used in much contemporary sculpture. Sculptures covered by the term in modern art are likely to be over two metres in at least one dimension, and sufficiently large not to need a high "plinth, though they may have one. Many are still commissioned as "public art, often for placing at outdoor sites.
