Tapered four-sided pillar, originally erected in pairs at the entrance to ancient Egyptian temples. The Egyptian obelisk was carved from a single piece of stone, usually granite, and embellished with hieroglyphics. It was wider at its square or rectangular base than at its pyramidal top, and could be over 100 ft (30 m) high. During the Roman empire, many obelisks were transported from Egypt to Italy. A well-known modern obelisk is the Washington Monument.

An obelisk (from Greek ὀβελίσκος - obeliskos, diminutive of ὀβελός - obelos, "spit, nail, pointed pillar) (المسلة Al-Masalla in Arabic) is a tall, narrow, four-sided, tapering monument which ends in a pyramidal top. Ancient obelisks were made of a single piece of stone (a monolith); however, most modern obelisks are made of individual stones, and can even have interior spaces. The original form is Egyptian and all subsequent versions are derived from the original Egyptian pattern.
Because of the Enlightenment-era association of Egypt with mortuary arts, (and generally with great antiquity), obelisks became associated with timelessness and memorialization.
There are many smaller obelisks or similar forms to be found in European and American cemeteries, and may be from a few meters in height.
Obelisks were prominent in the architecture of the ancient Egyptians, who placed them in pairs at the entrance of temples. The word "obelisk" is of Greek rather than Egyptian origin because Herodotus, the Greek traveler, was the first to describe the objects. Twenty-nine ancient Egyptian obelisks are known to have survived, plus the "Unfinished Obelisk" found partly hewn from its quarry at Aswan. These obelisks are now dispersed around the world, and only nine remain in Egypt.
The obelisk symbolized the sun god Amon Re, and during the brief religious reformation of Akhenaten was said to be a petrified ray of the Aten, the sundisk. It was also thought that the god existed within the structure.
It is hypothesized by New York University Egyptologist Patricia Blackwell Gary and Astronomy senior editor Richard Talcott that the shapes of the ancient Egyptian pyramid and obelisk were derived from natural phenomena associated with the sun (the sun-god Ra being the Egyptians' greatest deity). The pyramid and obelisk would have been inspired by previously overlooked astronomical phenomena connected with sunrise and sunset: the zodiacal light and sun pillars respectively.
The Ancient Romans were strongly influenced by the obelisk form, to the extent that there are now more than twice as many obelisks standing in Rome as remain in Egypt. All fell after the Roman period except for the Vatican obelisk and were re-erected in different locations.
The tallest Egyptian obelisk graces the square in front of the Lateran Basilica in Rome. this one is 105.6 feet tall and weighs 455 tons
Not all the Egyptian obelisks re-erected in the Roman Empire were set up at Rome. Herod the Great imitated his Roman patrons and set up a red granite Egyptian obelisk in the hippodrome of his grand new city Caesarea in northern Judea. This one is about 40 feet tall and weighs about 100 tons. It was discovered by archaeologists and has been re-erected at its former site.
In Constantinople, the Eastern Emperor Theodosius shipped an obelisk in AD 390 and had it set up in his hippodrome, where it has weathered Crusaders and Seljuks and stands in the Hippodrome square in modern Istanbul. This one originally stood 95 feet tall weighing 380 tons its lower half reputedly also once stood in Istanbul but is now lost. It now stands 65 feet tall probably not much if any more than 200 tons.
Rome is the obelisk capital of the world. The most prominent is the 25.5 m / 83.6 ft high 331 tons obelisk at Saint Peter's Square in Rome. The obelisk had stood since AD 37 on its site on the wall of the Circus of Nero, flanking St Peter's Basilica:
Re-erecting the obelisk had daunted even Michelangelo, but Sixtus V was determined to erect it in front of St Peter's, of which the nave was yet to be built, and had a full-sized wooden mock-up erected within months of his election. Domenico Fontana, the assistant of Giacomo Della Porta in the Basilica's construction, presented the Pope with a little model crane of wood and a heavy little obelisk of lead, which Sixtus himself was able to raise by turning a little winch with his finger. Fontana had the project. The obelisk, half-buried in the debris of the ages, was first excavated as it stood; then it took from April 30 to May 17 1586 to move it on rollers to the Piazza: it required nearly 1000 men, 140 carthorses, 47 cranes. The re-erection, scheduled for September 14, the Feast of the Exaltation of the Cross, was watched by a large crowd. It was a famous feat of engineering, which made the reputation of Fontana, who detailed it in a book illustrated with copperplate etchings, Della Trasportatione dell'Obelisco Vaticano et delle Fabriche di Nostro Signore Papa Sisto V (1590), which itself set a new standard in communicating technical information and influenced subsequent architectural publications by its meticulous precision. Before being re-erected the obelisk was exorcised. It is said that Fontana had teams of relay horses to make his getaway if the enterprise failed. When Carlo Maderno came to build the Basilica's nave, he had to put the slightest kink in its axis, to line it precisely with the obelisk.
An obelisk stands in front of the church of Trinità dei Monti, at the head of the Spanish Steps. Another obelisk in Rome is sculpted as carried on the back of an elephant. Rome lost one of its obelisks, which had decorated the temple of Isis, where it was uncovered in the 16th century. The Medici claimed it for the Villa Medici, but in 1790 they managed to move it to the Boboli Gardens attached to the Palazzo Pitti in Florence, and left a replica in its stead.
Several more of the original Egyptian obelisks have been shipped and re-erected around the world. The best-known examples outside Rome are the pair of 21 m /68 ft Cleopatra's Needles in London(69 feet 187 tons) and New York City(70 feet 193 tons) and the 23 m / 75 ft 227 tons obelisk at the Place de la Concorde in Paris.
There are 29 known ancient Egyptian obelisks in the following locations:
A number of obelisks were carved in the ancient Axumite Kingdom of Ethiopia. The most notable example – the 24 m high Obelisk of Axum carved around the 4th century AD – was looted by the Italians after the Second Italo-Abyssinian War and taken to Rome in 1937 where it stood in the Piazza di Porta Capena. Italy agreed in a 1947 UN agreement to return the obelisk but did not affirm its agreement until 1997, after years of pressure. In 2003 the Italian government made the first steps toward its return, and in 2008 it was finally re-erected.
The largest obelisk, Great Stele at Axum, now fallen, at 33 m high and 3 by 2 meters at the base (520 tons) is one of the largest single pieces of stone ever worked in human history (the largest is either at Baalbek or the Ramesseum) and probably fell during erection or soon after, destroying a large part of the massive burial chamber underneath it. The obelisks, properly termed stelae or the native hawilt or hawilti as they do not end in a pyramid, were used to mark graves and underground burial chambers. The largest of the grave markers were for royal burial chambers and were decorated with multi-story false windows and false doors, while nobility would have smaller less decorated ones. While there are only a few large ones standing, there are hundreds of smaller ones in various "stelae fields".
