Pyramid

pyramid.
pyramid. The true pyramid exists only in Egypt, though the term has also been applied to similar structures in other countries. Egyptian pyramids are square in plan and their triangular sides, which directly face the points of the compass, slope upwards at approximately a 50° angle from the ground and meet at an apex. The prototype for the pyramid are the mastabas of the Old Kingdom (2680–2565 B.C.), which are rectangular in plan and have only two sloping sides. After these came the step-pyramid at Sakkara, built c.2620 B.C., which soon evolved into the straight-sided true pyramid. This monumental structure was developed around the IV dynasty and continued to be the favored form for royal burial through the VI dynasty.
Each monarch built his own pyramid in which his mummified body might be preserved for eternity away from human view and sacrilege. As a result of the lack of sophisticated machinery, the construction of each pyramid took many years and required measureless amounts of building materials and labor. Entrance into a pyramid is through an opening in the northern wall. A small passage, traversing lesser chambers, leads to the sepulchral room deep beneath the surface. Stone blocks forming a gable divert the weight of the great masonry masses over these chambers. Though the pyramids were usually built of rough stone blocks laid up in horizontal courses, many were constructed of mud bricks with a stone casing.
The three pyramids of Giza near Cairo, all of the IV dynasty, are the largest and finest of their kind. The Great Pyramid of Khufu or Cheops (begun c.2680 B.C.) was designated one of the Seven Wonders of the World and is the largest pyramid ever built. A solid mass of limestone blocks covering 13 acres (5.3 hectares), it was originally 756 ft (230 m) along each side of its base and 482 ft (147 m) high. It has several passages, two large chambers in addition to one beneath the ground level, and two small air chambers for ventilation.
Although not true pyramids, pyramidical structures were also built by the Mesopotamians and by the Maya of Mexico and Central America. Mesopotamian ziggurat was square in plan and built up in receding terraces. Mayan pyramids, built in steep, receding blocks, also were topped by ritual chambers, and in some cases, possessed an interior crypt. Stepped funeral pyramids dating from the 4th cent. B.C. were discovered in the 1990s in the Altai region of Siberia. The Romans built small pyramidical tombs of which the most famous was the Pyramid of Cestius (62 B.C.–12 B.C.) in Rome. Built of concrete faced with marble, it has an interior tomb vault and is 116 ft (35 m) high. Many modern architects have admired pyramids for their pure geometry. In the reconstruction of the Louvre in Paris, architect I. M. Pei added a pyramidal entrance pavilion (1987–89).

Sphinx

sphinx
sphinx (sfingks) [key], mythical beast of ancient Egypt, frequently symbolizing the pharaoh as an incarnation of the sun god Ra. The sphinx was represented in sculpture usually in a recumbent position with the head of a man and the body of a lion, although some were constructed with rams' heads and others with hawks' heads. Thousands of sphinxes were built in ancient Egypt; the most famous is the Great Sphinx at Giza, a colossal figure sculptured out of natural rock, near the pyramid of Khafre. It was considered by the ancients one of the Seven Wonders of the World.
Sphinxes, however, were not peculiar to Egypt; represented in various shapes and forms, they were common throughout the ancient Middle East and Greece. In Greek mythology and art the Sphinx was a winged monster with the head and breasts of a woman and the body of a lion. In the legend of Oedipus she acts as a destructive agent of the gods, posing the riddle of the three ages of man: “What walks on four feet in the morning, on two at noon, and on three in the evening?” She killed all who failed to answer her question until Oedipus solved the riddle by saying, “Man crawls on all fours as a baby, walks upright in the prime of life, and uses a staff in old age.” The Sphinx then killed herself.

Mausoleum

mausoleum
mausoleum (môsulē'um) [key], a sepulchral structure or tomb, especially one of some size and architectural pretension, so called from the sepulcher of that name at Halicarnassus, Asia Minor, erected (c.352 B.C.) in memory of Mausolus of Caria. It was a magnificent white marble structure, considered by the ancients one of the Seven Wonders of the World.
Presumably in the form of an Ionic peristyle set on a lofty and massive base that contained the sarcophagus, it was surmounted by a stepped pyramid on whose truncated apex was a marble quadriga, or four-horse chariot. It was richly decorated with sculpture, including works of Scopas and, quite probably, of Praxiteles. The building itself was demolished for the purpose of reusing the material, but some of the sculpture was recovered (1846) for the British Museum.
A notable Roman mausoleum (135–39) is that of Hadrian in Rome. It was originally a great circular drum sheathed in marble and perhaps covered by a conical stepped roof of masonry; its form, however, has been changed beyond recognition. It is now called Castel Sant' Angelo.
Under the Mughal emperors of India was built a remarkable series of domed mausoleums, many of them used as pleasure pavilions during the owner's lifetime. The most celebrated mausoleum, built by Shah Jahan at Agra, is known as the Taj Mahal. Notable mausoleums of modern times are those of Napoleon under the Dôme des Invalides, Paris; of President U. S. Grant on Riverside Drive, New York City; and of Lenin in Red Square, Moscow. In the United States the term mausoleum is used loosely to describe any sepulchral building above the surface of the ground.

Seven Wonder's Of The Ancient World

Phidias
Phidias or Pheidias (both: fid'ēus) [key], c.500–c.432 B.C., Greek sculptor, one of the greatest sculptors of ancient Greece. No original in existence can be attributed to him with certainty, although numerous Roman copies in varying degrees of supposed fidelity exist. However, the estimates of ancient writers, their descriptions of his statues, and his influence on all later sculpture have secured his fame. His greatest achievements were the Athena Parthenos at Athens and the Zeus in the temple of Olympia, both colossal figures of chryselephantine workmanship (draperies of beaten gold, flesh parts incrusted with ivory). The Athena (dedicated in the Parthenon c.447–439 B.C.) was the chief treasure of Athens. It was destroyed in antiquity, but several copies are preserved (National Mus. of Antiquities, Athens). It was also represented on coins and gems. The Zeus (c.435 B.C.), counted as one of the Seven Wonders of the World, was a majestic bearded figure seated upon a magnificently ornamented throne and wearing a mantle strewn with sculptured decorations. Terra-cotta molds, found in 1955–56 at Olympia on the site identified as Phidias' workshop, showed that the gold for the drapery had been hammered into the molds and then further decorated with glass inlays. Works of the master's younger years include a colossal bronze Athena (called the Promachos), the Athena Lemnia for the Acropolis, and a chryselephantine Athena for Pellene. Phidias has traditionally been credited with having been in charge of the Parthenon sculptures and other great works on the Acropolis, done for Pericles; but it is probable that they were made by pupils and assistants. Part of the frieze is now in the British Museum (see Elgin Marbles).

Seven Wonder's Of The Ancient World

Artemis
Artemis (är'tumis) [key], in Greek religion and mythology, Olympian goddess, daughter of Zeus and Leto and twin sister of Apollo. Artemis' early worship, especially at Ephesus, identified her as an earth goddess, similar to Astarte. In later legend, however, she was primarily a virgin huntress, goddess of wildlife and patroness of hunters. Of the many animals sacred to her, the bear was most important. Artemis valued her chastity so highly that she took terrible measures against anyone who even slightly threatened her (e.g., Actaeon). She was attended by nymphs, whose virginity she guarded as jealously as her own. She was also an important goddess in the life of women, concerned with marriage and with the young of all creatures. As the complement to Apollo, she was often considered a moon goddess and as such was identified with Selene and Hecate. In ancient Greece, the worship of Artemis was widespread. The Romans identified her with Diana. She is mentioned in the biblical book of Acts of the Apostles, where she appears to be in competition with the god of the Christians.

Halicarnassus
Halicarnassus (hăl"ikärnă'sus) [key], ancient city of Caria, SW Asia Minor, on the Ceramic Gulf (now the Gulf of Kos) and on the site of the modern city of Bodrum, Turkey. Halicarnassus was Greek in origin, but there were Carian inhabitants. Except for a brief period in the 5th cent. B.C., the city was not intimately concerned with Greek affairs. As a Persian vassal it was ruled by tyrants and participated in Xerxes' invasion of Greece (480 B.C.), but after the expulsion of the tyrants (460–455) it joined the Delian League. A dynasty of Carian kings in the 4th cent. B.C. was made famous by Mausolus, whose wife, Artemisia, built him a magnificent tomb (see mausoleum), considered one of the Seven Wonders of the World. Alexander the Great conquered the city (c.334 B.C.). It was the birthplace of Herodotus and of Dionysius of Halicarnassus.

Seven Wonder's Of The Ancient World

Colossus of Rhodes
Colossus of Rhodes (kulos'us) [key], large statue of Helios, the sun god, destroyed by an earthquake in antiquity. Consider one of the Seven Wonders of the World by the ancients, it was built in part by Chares of Lindus (Rhodes) between 292 and 280 B.C. Its bronze was taken from the machines and tools left behind by Demetrius I after his unsuccessful siege of Rhodes. According to legend, the 100 ft (30.5 m) statue stood astride the harbor and ships passed between its legs. In reality, it stood on a promontory overlooking the harbor, and the representational type is well known from images on coins of the same period.
Colossi also existed elsewhere in the ancient world. In Egypt, for example, there were many colossuses, 50 to 60 ft (15.2 to 18.3 m) high. The Athena Parthenos on the Acropolis at Athens and the Zeus in the temple at Olympia in Greece were other examples. In Japan, the word daibutsu describes colossal statues of Buddha, usually over 16 ft (5 m) in height. The most notable are those at Nara, Kamakura, and Kyoto. Of two colossal figures of Jesus in South America, one is at Rio de Janeiro, and the other, the Christ of the Andes, on the boundary between Argentina and Chile. An example of a modern colossus is the Statue of Liberty in New York harbor.

Pharos
Pharos (fâr'os) [key], peninsula, extending into the Mediterranean Sea, N Egypt, NE Africa, forming two harbors at Alexandria. Originally an island, it was joined to the mainland by a mole, constructed by order of Alexander the Great. On Pharos stood the celebrated lighthouse completed (c.280 B.C.) by Ptolemy II, which is usually included among the ancient Seven Wonders of the World. No precise description of it has survived, and modern estimates of its height vary between 200 and 600 ft (60–180 m). It was destroyed by an earthquake in the 14th cent.
