Anastylosis is an archaeological term for a reconstruction technique whereby a ruined building or monument is restored using the original architectural elements to the greatest degree possible. It is also sometimes used to refer to a similar technique for restoring broken pottery and other small objects.
Methodology
The intent of anastylosis is to rebuild, from as much of the original materials that is left after usually thousands of years of abuse, historical architectural monuments which have fallen into ruin. This is done by placing components back into their original positions. Where standing buildings are at risk of collapse, the method may entail the preparation of drawings and measurements, piece-by-piece disassembly, and careful reassembly, with new materials as required for structural integrity; occasionally this may include new foundations. When elements or parts are missing, modern materials may be substituted, such as plaster, cement, and synthetic resins. The international Venice Charter of 1964 details criteria for anastylosis. First, the original condition of the structure must be confirmed scientifically. Second, the proper placement of each recovered component must be determined. Third, supplemental components must be limited to those necessary for stability, and must be recognizable as replacement materials. New construction for the sake of filling in apparent lacunae is not allowed.
Criticism
Anastylosis has its detractors in the scientific community. In effect, the method poses several problems:
no matter how rigorous preparatory studies are, any errors of interpretation will result in errors, often undetectable or incorrigible, in reconstruction.
damage to the original components is practically inevitable.
an element may be, or may have been reused in, or may have originated in, different buildings or monuments from different periods. To use it in one reconstruction obviates its use in others.
Examples
Greece
A primitive anastylosis was carried out in 1836 at the Acropolis in Athens, where the Temple of Athena Nike was re-erected from remaining parts. Starting in 1902, the Greek architect Nikolas Balanos used anastylosis in order to restore a collapsed portion of the Parthenon, restore the Erechtheion, and rebuild the Nike Temple a second time. Iron clamps and plugs which had been used earlier had started to rust and had caused heavy damage to the original structure. These were removed and replaced with precious metal clamps. When the temple was once again rebuilt additional newly identified original fragments were added. Currently, anastylosis is being applied to the Parthenon.
Early in the 20th century, Dutch archaeologists carried out anastylosis of the stupa at the Buddhist temple complex at Borobudur in Java, Indonesia between 1907 and 1911. The PrambananHindu temple complex was excavated and was partially reconstructed between 1911 and 1953, also reconstructed using anastylosis method. The recent practice of anastylosis in Indonesia is the reconstruction of Kedulan temple, built in 869, the temple was buried under volcanic layers for centuries, until was discovered in 1993. The restoration of the entire Kedulan Temple complex is expected to be completed by the end of 2018.
has several buildings sufficiently well preserved to allow such anastylosis: the Tetrapylon ; the east end of the Sebasteion’s South Building ; the Doric logeion of the Theatre ; and the Propylon of the Sebasteion complex.
