A stele (pron.: //, historically //; Greek: στήλη stēlē; plural: στήλαι stēlai), also stela (plural stelae //) Latin, is a stone or wooden slab, generally taller than it is wide, erected for funerals or commemorative purposes, most usually decorated with the names and titles of the deceased or living — inscribed, carved in relief (bas-relief, sunken-relief, high-relief, and so forth), or painted onto the slab. It can also be used as a territorial marker to delineate land ownership.
Stelae were also used to publish laws and decrees, to record a ruler's exploits and honors, to mark sacred territories or mortgaged properties, as territorial markers, as the boundary stelae of Akhenaton at Amarna, or to commemorate military victories. They were widely used in the Ancient Near East, Mesopotamia, Greece, Egypt, Eritrea, Ethiopia, and, most likely independently, in China and elsewhere in the Far East, and, more surely independently, by Mesoamerican civilisations, notably the Olmec and Maya. The huge number of stelae surviving from ancient Egypt and in Central America constitute one of the largest and most significant sources of information on those civilisations. An informative stele of Tiglath-Pileser III is preserved in the British Museum. Two stelae built into the walls of a church are major documents relating to the Etruscan language.
Unfinished standing stones, set up without inscriptions from Libya in North Africa to Scotland were monuments of pre-literate Megalithic cultures in the Late Stone Age. The Pictish stones of Scotland, often intricately carved, date from between the 6th and 9th centuries.
An obelisk is a specialized kind of stele. The Insular high crosses of Ireland and Britain are specialized stelae. Likewise, the Totem pole of North and South America is a type of stelae. Gravestones with inscribed epitaph are also kinds of stelae.
Most recently, in the Memorial to the Murdered Jews of Europe in Berlin, the architect Peter Eisenman created a field of some 2,700 blank stelae. The memorial is meant to be read not only as the field, but also as an erasure of data that refer to memory of the Holocaust.
Stelae (Chinese: 碑; pinyin: béi) have been the major medium of stone inscription in China since the Tang dynasty. Chinese stelae are generally rectangular stone tablets upon which Chinese characters are carved intaglio with a funerary, commemorative, or edifying text. They can commemorate talented writers and officials, inscribe poems, portraits, or maps, and frequently contain the calligraphy of famous historical figures.
Chinese stelae from before the Tang dynasty are rare: there are a handful from before the Qin dynasty, roughly a dozen from the Western Han, 160 from the Eastern Han, and several hundred from the Wei, Jin, Southern and Northern dynasties, and Sui dynasty. During the Han dynasty, tomb inscriptions (Chinese: 墓誌; pinyin: mùzhì) containing biographical information on deceased people began to be written on stone tablets rather than wooden ones.
Erecting stelae at tombs or temples eventually became a widespread social and religious phenomenon. Emperors found it necessary to promulgate laws, regulating the use of funerary stelae by the population. The Ming Dynasty laws, instituted in the 14th century by its founder the Hongwu Emperor, listed a number of stele types available as status symbols to various ranks of the nobility and officialdom: the top noblemen and mandarins were eligible for stelae installed on top of a stone tortoise and crowned with hornless dragons, while the lower-level officials had to be satisfied with steles with plain rounded tops, standing on simple rectangular pedestals.
Stelae are found at nearly every significant mountain and historical site in China. The First Emperor made five tours of his domain in the 3rd century BC and had Li Si make seven stone inscriptions commemorating and praising his work, of which fragments of two survive. One of the most famous mountain stelae is the 13 m (43 ft) high stele at Mount Tai with the personal calligraphy of Emperor Xuanzong of Tang commemorating his imperial sacrifices there in 725.
A number of such stone monuments have preserved the origin and history of China's minority religious communities. The 8th-century Christians of Xi'an left behind the Nestorian Stele, which survived adverse events of the later history by being buried underground for several centuries. Steles created by the Kaifeng Jews in 1489, 1512, and 1663, have survived the repeated flooding of the Yellow River that destroyed their synagogue several times, to tell us something about their world. China's Muslim have a number of steles of considerable antiquity as well, often containing both Chinese and Arabic text.
Thousands of steles, surplus to the original requirements, and no longer associated with the person they were erected for or to, have been assembled in Xi'an's Stele Forest Museum, which is a popular tourist attraction. Elsewhere, many unwanted steles can also be found in selected places in Beijing, such as Dong Yue Miao, the Five Pagoda Temple, and the Bell Tower, again assembled to attract tourists and also as a means of solving the problem faced by local authorities of what to do with them. The long, wordy, and detailed inscriptions on these steles are almost impossible to read for most are lightly engraved on white marble in characters only an inch or so in size, thus being difficult to see since the slabs are often ten or more feet tall.
There are more than 100,000 surviving stone inscriptions in China. However, only approximately 30,000 have been transcribed or had rubbings made, and fewer than those 30,000 have been formally studied.
