Lifting bosses or handling bosses are protrusions intentionally left on stones by masons to facilitate maneuvering the blocks with ropes and levers. [1] [2]
They are an important feature of ancient and classical construction, and were often not cut away, despite having fulfilled their purpose. Sometimes this was the result of a cost-saving measure or a construction halt. Other times bosses were left as a stylistic element, and even if dressed back, a remnant of them was kept to make their existence obvious. [3]
The Great Pyramid of Giza is the largest Egyptian pyramid and served as the tomb of pharaoh Khufu, who ruled during the Fourth Dynasty of the Old Kingdom. Built in the early 26th century BC, over a period of about 27 years, the pyramid is the oldest of the Seven Wonders of the Ancient World, and the only wonder that has remained largely intact. It is the most famous monument of the Giza pyramid complex, which is part of the UNESCO World Heritage Site "Memphis and its Necropolis". It is situated at the northern end of the line of the three pyramids at Giza.
Stonemasonry or stonecraft is the creation of buildings, structures, and sculpture using stone as the primary material. Stonemasonry is the craft of shaping and arranging stones, often together with mortar, to form structures.
Ashlar is finely dressed stone, either an individual stone that has been worked until squared, or a structure built from such stones. Ashlar is the finest stone masonry unit, generally rectangular cuboid, mentioned by Vitruvius as opus isodomum, or less frequently trapezoidal. Precisely cut "on all faces adjacent to those of other stones", ashlar is capable of very thin joints between blocks, and the visible face of the stone may be quarry-faced or feature a variety of treatments: tooled, smoothly polished or rendered with another material for decorative effect.
Rustication is a range of masonry techniques used in classical architecture giving visible surfaces a finish texture that contrasts with smooth, squared-block masonry called ashlar. The visible face of each individual block is cut back around the edges to make its size and placing very clear. In addition the central part of the face of each block may be given a deliberately rough or patterned surface.
The pyramid of Menkaure is the smallest of the three main pyramids of the Giza pyramid complex, located on the Giza Plateau in the southwestern outskirts of Cairo, Egypt. It is thought to have been built to serve as the tomb of the Fourth Dynasty Egyptian Pharaoh Menkaure.
Talatat are limestone blocks of standardized size used during the 18th Dynasty reign of the Pharaoh Akhenaten in the building of the Aton temples at Karnak and Akhetaten. The standardized size and their small weight made construction more efficient. Their use may have begun in the second year of Akhenaten's reign. After the Amarna Period talatat construction was abandoned, apparently not having withstood the test of time.
Cyclopean masonry is a type of stonework found in Mycenaean architecture, built with massive limestone boulders, roughly fitted together with minimal clearance between adjacent stones and with clay mortar or no use of mortar. The boulders typically seem unworked, but some may have been worked roughly with a hammer and the gaps between boulders filled in with smaller chunks of limestone.
Egyptian pyramid construction techniques are the controversial subject of many hypotheses. These techniques seem to have developed over time; later pyramids were not constructed in the same way as earlier ones. Most of the construction hypotheses are based on the belief that huge stones were carved from quarries with copper chisels, and these blocks were then dragged and lifted into position. Disagreements chiefly concern the methods used to move and place the stones.
Inca architecture is the most significant pre-Columbian architecture in South America. The Incas inherited an architectural legacy from Tiwanaku, founded in the 2nd century B.C.E. in present-day Bolivia. A core characteristic of the architectural style was to use the topography and existing materials of the land as part of the design. The capital of the Inca empire, Cuzco, still contains many fine examples of Inca architecture, although many walls of Inca masonry have been incorporated into Spanish Colonial structures. The famous royal estate of Machu Picchu is a surviving example of Inca architecture. Other significant sites include Sacsayhuamán and Ollantaytambo. The Incas also developed an extensive road system spanning most of the western length of the continent and placed their distinctive architecture along the way, thereby visually asserting their imperial rule along the frontier.
A corbel arch is an arch-like construction method that uses the architectural technique of corbeling to span a space or void in a structure, such as an entranceway in a wall or as the span of a bridge. A corbel vault uses this technique to support the superstructure of a building's roof.
Coricancha, Koricancha, Qoricancha or Qorikancha was the most important temple in the Inca Empire. It is located in Cusco, Peru, which was the capital of the empire.
Core-and-veneer, brick and rubble, wall and rubble, ashlar and rubble, and emplekton all refer to a building technique where two parallel walls are constructed and the core between them is filled with rubble or other infill, creating one thick wall. Originally, and in later poorly constructed walls, the rubble was not consolidated. Later, mortar and cement were used to consolidate the core rubble and produce sturdier construction.
The history of construction embraces many other fields, including structural engineering, civil engineering, city growth and population growth, which are relatives to branches of technology, science, history, and architecture. The fields allow both modern and ancient construction to be analyzed, as well as the structures, building materials, and tools used.
Meleke, also transliterated melekeh or malaki, is a lithologic type of white, coarsely-crystalline, thickly bedded-limestone found in the Judaean Mountains in Israel and the State of Palestine. It has been used in the traditional architecture of Jerusalem since ancient times, especially in Herodian architecture. Though it is often popularly referred to as Jerusalem stone, that phrase can refer to a number of different types of stone found and used in or associated with Jerusalem.
Ablaq is an architectural technique involving alternating or fluctuating rows of light and dark stone. It is an Arabic term describing a technique associated with Islamic architecture in the Arab world. It may have its origins in earlier Byzantine architecture in the region, where alternating layers of white stone and orange brick were used in construction.
The Temple of Jupiter is a colossal Roman temple, the largest of the Roman world, situated at the Baalbek complex in Heliopolis Syriaca. The temple served as an oracle and was dedicated to Jupiter Heliopolitanus.
Hellenistic fortifications are defense structures constructed during the Hellenistic Period of ancient Greek civilization. These included fortification walls, towers, and gates. Expansion of Greek territory during the Hellenistic Period from Alexander the Great's conquests created the necessity to build new fortifications with new settlements. This, combined with developing military technology, led to changes in style of architecture specific to the Hellenistic Period.
The Palacio de Aldama is a neoclassical mansion located diagonally opposite to the old Plaza del Vapor, and in front of the old Campo de Marte; present day Parque de la Fraternidad, in Havana, Cuba. Built in 1840 by the Dominican architect and engineer Manuel José Carrera, its main facade of columns spans one block on Calle Amistad between Calles Reina and Estrella.
