Statue of Zeus at Olympia

The Statue of Zeus at Olympia was one of the classic Seven Wonders of the Ancient World. It was made by the famed Greek sculptor of the Classical period, Phidias, circa 432 BC on the site where it was erected in the temple of Zeus, Olympia, Greece

The seated statue, some 12 metres (39 feet) tall, occupied the whole width of the aisle of the temple built to house it. "It seems that if Zeus were to stand up," the geographer Strabo noted early in the 1st century BC, "he would unroof the temple."[2] Zeus was a chryselephantine sculpture, made of ivory and accented with gold plating. No copy, in marble or bronze, has survived, though there are recognizable but approximate versions on coins of Elis and Roman coins and engraved gems[3] but a very detailed description of the sculpture and the throne was recorded by the traveller Pausanias, in the second century AD.

In the sculpture, he was wreathed with shoots of the olive and seated on a magnificent throne of cedarwood, inlaid with ivory, gold, ebony, and precious stones. In Zeus' right hand there was a small statue of crowned Nike, goddess of victory, also chryselephantine, who was, and in his left hand, a sceptre inlaid with metals, on which an eagle perched.[4] Plutarch, in his Life of the Roman general Aemilius Paulus, records that the victor over Macedon “was moved to his soul, as if he had beheld the god in person,” while the Greek orator Dio Chrysostom declared that a single glimpse of the statue would make a man forget his earthly troubles.[5]
The date of the statue, in the third quarter of the fifth century BC, long a subject of debate, was confirmed archaeologically.

According to a legend, when Phidias was asked what inspired him -- whether he climbed Olympos to see Zeus, or whether Zeus came down from Olympos so that Phidias could see him -- the artist answered that he portrayed Zeus according to Book One, verses 528 - 530 of Homer´s Iliad [6]:
ἦ καὶ κυανέῃσιν ἐπ' ὀφρύσι νεῦσε Κρονίων
ἀμβρόσιαι δ' ἄρα χαῖται ἐπερρώσαντο ἄνακτος
κρατὸς ἀπ' ἀθανάτοιο μέγαν δ' ἐλέλιξεν Ὄλυμπον.
He spoke, the son of Kronos, and nodded his head with the dark brows,
and the immortally anointed hair of the great god
swept from his divine head, and all Olympos was shaken

Loss and destruction

The circumstances of its eventual destruction are a source of debate: the eleventh-century Byzantine historian Georgios Kedrenos[8] recorded the tradition that it was carried off to Constantinople, where it was destroyed in the great fire of the Lauseion, in 475.[9] Others argue that it perished with the temple when it burned in 425 AD. According to Lucian of Samosata in the later second century, "they have laid hands on your person at Olympia, my lord High-Thunderer, and you had not the energy to wake the dogs or call in the neighbours; surely they might have come to the rescue and caught the fellows before they had finished packing up the swag."[10]

Phidias' workshop rediscovered

Perhaps the greatest discovery in terms of finding out about this wonder came in 1954-1958 with the excavation of the workshop at Olympia where Phidias created the statue. Tools, terracotta molds and a cup inscribed "I belong to Pheidias" were found here, where the traveller Pausanius said the Zeus was constructed. This has enabled archaeologists to re-create the techniques used to make the great work and confirmed its date.

Hanging Gardens of Babylon

The Hanging Gardens of Babylon (also known as the Hanging Gardens of Semiramis) (near present-day Al Hillah in Iraq, formerly Babylon) are considered one of the original Seven Wonders of the World. They were built by Nebuchadnezzar II around 600 BCE. He is reported to have constructed the gardens to please his wife, Amytis of Media, who longed for the trees and fragrant plants of her homeland.[1] The gardens were destroyed by several earthquakes after the 2nd century BCE.

The lush Hanging Gardens are extensively documented by Greek historians such as Strabo and Diodorus Siculus. Through the ages, the location may have been confused with gardens that existed at Nineveh, since tablets from there clearly show gardens. Writings on these tablets describe the possible use of something similar to an Archimedes' screw as a process of raising the water to the required height.

The Greek Historian Strabo:

"Babylon, too, lies in a plain; and the circuit of its wall is three hundred and eighty-five stadia. The thickness of its wall is thirty-two feet; the height thereof between the towers is fifty cubits; that of the towers is sixty cubits; and the passage on top of the wall is such that four-horse chariots can easily pass one another; and it is on this account that this and the hanging garden are called one of the Seven Wonders of the World. The garden is quadrangular in shape, and each side is four plethra in length. It consists of arched vaults, which are situated, one after another, on checkered, cube-like foundations.

The checkered foundations, which are hollowed out, are covered so deep with earth that they admit of the largest of trees, having been constructed of baked brick and asphalt — the foundations themselves and the vaults and the arches. The ascent to the uppermost terrace-roofs is made by a stairway; and alongside these stairs there were screws, through which the water was continually conducted up into the garden from the Euphrates by those appointed for this purpose. For the river, a stadium in width, flows through the middle of the city; and the garden is on the bank of the river."[2]

The Greek Historian Diodorus:

"The Garden was 100 feet (30 m) long by 100 feet (30 m) feet wide and built up in tiers so that it resembled a theatre. Vaults had been constructed under the ascending terraces which carried the entire weight of the planted garden; the uppermost vault, which was seventy-five feet high, was the highest part of the garden, which, at this point, was on the same level as the city walls.

The roofs of the vaults which supported the garden were constructed of stone beams some sixteen feet long, and over these were laid first a layer of reeds set in thick tar, then two courses of baked brick bonded by cement, and finally a covering of lead to prevent the moisture in the soil penetrating the roof. On top of this roof enough topsoil was heaped to allow the biggest trees to take root. The earth was leveled off and thickly planted with every kind of tree. And since the galleries projected one beyond the other, where they were sunlit, they contained conduits for the water which was raised by pumps in great abundance from the river, though no one outside could see it being done.

Hanging Gardens. Paracleisos going up to the top is like climbing a mountain. Each terrace rises up from the last like the syrinx, the pipes of pan, which are made of several tubes of unequal length. This gives the appearance of a theater. It was flanked by perfectly constructed walls twenty-six feet thick. The galleries were roofed with stone balconies. Above these there was the first of a bed of reeds with a great quantity of bitumen, then a double layer of baked bricks set in gypsum, then over that a covering of lead so that moisture from the soil heaped above it would not seep through. The earth was deep enough to contain the roots of the many varieties of trees which fascinated the beholder with their great size and their beauty. There was also a passage which had pipes leading up to the highest level and machinery for raising water through which great quantities of water were drawn from the river, with none of the process being visible from the outside."

Controversy over validity of existence
There is some controversy as to whether the Hanging Gardens were an actual creation or a poetic creation due to the lack of documentation of them in the chronicles of Babylonian history. In ancient writings the Hanging Gardens of Babylon were first described by Berossus, a Chaldean priest who lived in the late 4th century BCE. These accounts were later elaborated on by Greek historians.

Recent archaeological excavations of the palace in Iraq have uncovered evidence of a building with vaults and a well nearby. However, the location of the palace complex contradicts where Greek historians placed the Hanging Gardens, which was on the banks of the Euphrates River.
Recently there have been excavations on the banks of the Euphrates River of some substantial 25 meter-thick walls.[5] Also, excavations have shown that there may be some seeds scattered around this area which may suggest that the Gardens did exist after all.[citation needed]
A newer theory proposes that the garden was actually constructed under the orders of Sennacherib, who took the throne of Assyria in 705 BCE–681 BCE. During new studies of the location of Nineveh (Located on the eastern bank of the Tigris in ancient Assyria) his gardens were placed close to the entrance of his palace, on the bank of the river Tigris. It is possible that in the intervening centuries the two sites became confused, and the hanging gardens were attributed to Babylon

Great Pyramid of Giza (Anciant Wonders)

The Great Pyramid of Giza , also called Khufu's Pyramid or the Pyramid of Khufu, and Pyramid of Cheops, is the oldest and largest of the three pyramids in the Giza Necropolis bordering what is now Cairo, Egypt in Africa, and is the only remaining member of the Seven Wonders of the Ancient World. It is believed the pyramid was built as a tomb for Fourth dynasty Egyptian pharaoh Khufu (Cheops in Greek) and constructed over a 20 year period concluding around 2560 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Visibly all that remains is the underlying step-pyramid core structure seen today. Many of the casing stones that once covered the structure can still be seen around the base of the Great Pyramid. There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

There are three known chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was unfinished. The Queen's Chamber and King's Chamber are higher up within the pyramid structure. Despite precautions such as covering the entrance hole with casing and the portcullises, thieves had bypassed all the barriers even before the Old Kingdom had ended, digging through the soft limestone and breaking a corner of Khufu's sarcophagus while removing the lid.[citation needed] Other sources suggest that the sarcophagus never had a lid. The Great Pyramid is the only pyramid known to contain both ascending and descending passages.

The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles.

Wonder of the Ancient World

It is believed the pyramid was built as a tomb for Fourth dynasty Egyptian pharaoh Khufu and constructed over a 20 year period concluding around 2560 BC.[2] Khufu's vizier, Hemon, or Hemiunu, is believed by some to be the architect of the Great Pyramid.[3] It is thought that, at construction, the Great Pyramid was 280 Egyptian royal cubits tall, 146.6 meters, but with erosion and the loss of its pyramidion, its current height is 138.8 m. Each base side was 440 royal cubits, with each royal cubit measuring 0.524 meters.[4] The total mass of the pyramid is estimated at 5.9 million tonnes. The volume, including an internal hillock, is believed to be roughly 2,500,000 cubic metres.[5] The first precision measurements of the pyramid were done by Egyptologist Sir Flinders Petrie in 1880–82 and published as The Pyramids and Temples of Gizeh. Almost all reports are based on his measurements. Petrie found the pyramid is oriented 4' west of North and the second pyramid is similarly oriented

The Great Pyramid was the tallest man-made structure in the world for over 3,800 years,[7] unsurpassed until the 160 metre tall spire of Lincoln Cathedral was completed c. 1300. The accuracy of the pyramid's workmanship is such that the four sides of the base have a mean error of only 58 mm in length, and 1 minute in angle from a perfect square. The base is horizontal and flat to within 15 mm. The sides of the square are closely aligned to the four cardinal compass points to within 3 minutes of arc and is based not on magnetic north, but true north. The design dimensions, as confirmed by Petrie's survey and all those following this, are assumed to have been 280 cubits in height by 4x440 cubits around originally, and as these proportions equate to 2π to an accuracy of better than 0.05%, this was and is considered to have been the deliberate design proportion by Petrie, I. E. S. Edwards, and Miroslav Verner. Verner wrote "We can conclude that although the ancient Egyptians could not precisely define the value of π, in practise they used it".

Casing stones

At completion, the Great Pyramid was surfaced by white 'casing stones' – slant-faced, but flat-topped, blocks of highly polished white limestone. Visibly all that remains is the underlying step-pyramid core structure seen today. In AD 1301, a massive earthquake loosened many of the outer casing stones, which were then carted away by Bahri Sultan An-Nasir Nasir-ad-Din al-Hasan in 1356 in order to build mosques and fortresses in nearby Cairo. The stones can still be seen as parts of these structures to this day. Later explorers reported massive piles of rubble at the base of the pyramids left over from the continuing collapse of the casing stones which were subsequently cleared away during continuing excavations of the site. Nevertheless, many of the casing stones around the base of the Great Pyramid can be seen to this day in situ displaying the same workmanship and precision as has been reported for centuries. Petrie also found a different orientation in the core and in the casing measuring 193 cm ± 25 cm. He suggested a redetermination of north was made after the construction of the core, but a mistake was made, and the casing was built with a different orientation.[6]

Construction theories

Main article: Egyptian pyramid construction techniques
There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place. The disagreements center on the method by which the stones were conveyed and placed. A recent theory proposes that the building blocks were manufactured in-place from a kind of "limestone concrete". In addition to the many theories as to the techniques involved, there are also disagreements as to the kind of workforce that was used. One theory, suggested by the Greeks, posits that slaves were forced to work until the pyramid was done. This theory is no longer accepted in the modern era, however. Archaeologists believe that the Great Pyramid was built by tens of thousands of skilled workers who camped near the pyramids and worked for a salary or as a form of paying taxes until the construction was completed. The worker's cemeteries were discovered in 1990 by archaeologists Zahi Hawass and Mark Lehner. Verner posited that the labor was organized into a hierarchy, consisting of two gangs of 100,000 men, divided into five zaa or phyle of 20,000 men each, which may have been further divided according to the skills of the workers.[9]

Inside the Great Pyramid

There are three known chambers inside the Great Pyramid. These are arranged centrally, on the vertical axis of the pyramid. From the entrance, an 18 meter corridor leads down and splits in two directions. One way leads to the lowest and unfinished chamber. This chamber is cut into the bedrock upon which the pyramid was built. It is the largest of the three, but totally unfinished, only rough-cut into the rock. The other passage leads to the Grand Gallery (49 m x 3 m x 11 m) where it splits again. One tunnel leads to the Queen's Chamber, a misnomer, while the other winds to intersect with the descending corridor. The Grand Gallery itself features an ingenious corbel halloed design and several cut "sockets" spaced at regular intervals along the length of each side of its raised base with a "trench" running along its center length at floor level. What purpose these sockets served is unknown. An antechamber leads from the Grand Gallery to the King's Chamber.[2]

King's Chamber

At the end of the lengthy series of entrance ways leading into the pyramid interior is the structure's main chamber, the King's Chamber. This chamber was originally 10 x 20 x 11.2 cubits, or about 5.25 m x 10.5 m x 6 m, comprising a double 10x10 cubit square, and a height equal to half the double square's diagonal. Some believe that this is consistent with the geometric methods for determining the Golden Ratio φ (phi), which can be derived from other dimensions of the pyramid, such that if φ had been the design objective, then π automatically follows to 'square the circle'.[10]

The sarcophagus of the King's Chamber was hollowed out of a single piece of Red Aswan granite and has been found to be too large to fit through the passageway leading to the chamber. Whether the sarcophagus was ever intended to house a body is unknown. It is too short to accommodate a medium height individual without the bending of the knees, a technique not practiced in Egyptian burial, and no lid was ever found. The King's Chamber contains two small shafts that ascend out of the pyramid. These shafts were once thought to have been used for ventilation, but this idea was eventually abandoned leaving Egyptologists to now conclude they were instead used for ceremonial purposes. It is now thought that they were to allow the Pharaoh's spirit to rise up and out to heaven.[11]

Queen's Chamber

The Queen's Chamber is the middle and the smallest, measuring approximately 5.74 by 5.23 metres, and 4.57 metres in height. Its eastern wall has a large angular doorway or niche, Egyptologist Mark Lehner believes that the Queen's chamber was intended as a serdab, a structure found in several other Egyptian pyramids, and that the niche would have contained a statue of the interred. The Ancient Egyptians believed that the statue would serve as a "back up" vessel for the Ka of the Pharaoh, should the original mummified body be destroyed. The true purpose of the chamber, however, remains uncertain.[11] The Queens Chamber has a pair of shafts similar to those in the King's Chamber, which were explored using a robot, Upuaut 2, created by the German engineer Rudolf Gantenbrink. In 1992, Upuaut 2 discovered that these shafts were blocked by limestone "doors" with two eroded copper handles. The National Geographic Society filmed the drilling of a small hole in the southern door only to find another larger door behind it.[12] The northern passage, which was harder to navigate due to twists and turns, was also found to be blocked by a door.[13]

Unfinished chamber

The "unfinished chamber" lies 90 ft below ground level and is rough-hewn, lacking the precision of the other chambers. This chamber is dismissed by Egyptologists as being nothing more than a simple change in plans in which they believe it was intended to be the original burial chamber but later King Khufu changed his mind wanting it to be higher up in the pyramid.[14]

Main article: Giza pyramid complex
The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway connecting the two temples, and small mastaba tombs surrounding the pyramid for nobles. One of the small pyramids contains the tomb of queen Hetepheres (discovered in 1925), sister and wife of Sneferu and the mother of Khufu. There was a town for the workers of Giza, including a cemetery, bakeries, a beer factory and a copper smelting complex. A few hundred metres south-west of the Great Pyramid lies the slightly smaller Pyramid of Khafre, one of Khufu's successors who is also commonly considered the builder of the Great Sphinx, and a few hundred metres further south-west is the Pyramid of Menkaure, Khafre's successor, which is about half as tall. In May 1954, 41 blocking stones were uncovered close to the south side of the Great Pyramid. They covered a 30.8 meter long rock-cut pit that contained the remains of a 43 meter long ship of cedar wood. In antiquity, it had been dismantled into 650 parts comprising 1224 pieces. This funeral boat of Khufu has been reconstructed and is now housed in a museum on the site of its discovery. A second boat pit was later discovered nearby.
