The fabulous Leonid meteor storms have produced some of the most spectacular astronomical sights in history. These blizzards of light struck terror in people's hearts as the sky appeared to be falling. At other times, the glare of a bright bolide — perhaps followed by a tremendous explosion — can provoke anything from momentary surprise to vast destruction. Most meteoroids from space burn up as meteors — streaks of light — in the upper atmosphere. Only rarely do meteorites survive the plunge to reach the ground.
When they do, they become objects that pass from the heavens to Earth. As such, they have left a bigger imprint on human history than is generally realized.
The Iron Age One characteristic that separates humans from animals is that we make lots of tools. Our early ancestors fashioned their first tools from bone, wood, and stone. The Stone Age takes its name from when stone implements represented the highest technology available. Later, copper and its alloy with tin (bronze) were discovered, yielding more durable weapons and tools that offered significant advantages to their possessors. The Bronze Age started during the third millennium B.C.

For much of Eurasia, though its beginning and end varied widely around the world. Then around 1400 B.C. The Hittites of Asia Minor discovered that iron could be smelted from common ores to produce even more superior tools and armory, thus giving birth to the Iron Age. But how was iron discovered?
Copper's melting point (1,980° Fahrenheit) is low enough that simple fires can both reveal and smelt the ore, while iron's melting point (2,795°F) requires intentional discovery and special methods for processing. What gave the clue that iron should be sought and developed? Courtesy Freer Gallery of Art/Smithsonian Institution, Washington, D.C. Many late Bronze Age archaeological sites actually contain artifacts made of approximately 90 percent iron.
A famous example is the dagger recovered from the tomb of the 14th-century B.C. Egyptian pharaoh Tutankhamen. Chemical analyses show the dagger's 'impurities' to be largely nickel, a sure sign that the iron came from a meteorite.
So early metalsmiths found and used naturally smelted iron. They would have quickly realized its superiority. The Hittites and Sumerians acknowledged this connection by calling iron 'fire from heaven.' The Egyptian word for it means 'thunderbolt of heaven,' and the Assyrian term was 'metal of heaven.' With meteorites as an inspiration and a direct guide, the recognition of Earthly iron ores was probably inevitable.
Meteorites jump-started the Iron Age. When European explorers encountered a tribe of Inuits in northwestern Greenland in 1818, they were astounded to find knife blades, harpoon points, and engraving tools made of meteoric iron. Tools from the fabled Greenland meteorite had been found as far as 1,400 miles away, having been transported as treasured trade goods.
The area has no natural metal deposits, yet the abundant availability of meteoric iron allowed the polar hunters to skip to the Iron Age and helped them survive in an extremely harsh land.

Peary was led by a local guide to the site on Saviksoah Island off northern Greenland's Cape York in 1894. The meteorite was found in three primary masses, named the Tent or 'Ahnighito' (34 tons), the Woman (2½ tons), and the Dog (½ ton).
Over the next three years Peary's expeditions managed to load them onto ships despite savage weather, engineering problems, and having to build Greenland's only railway for transporting the behemoths. Upon arrival in New York City, the source of Greenland's Iron Age were sold to the American Museum of Natural History for $40,000, where they are now on display at the Hayden Planetarium. Ironically, even today, 27 percent of the world's nickel comes from mines in the large Sudbury meteor crater in Ontario, Canada. Sacred Stones In 205 B.C., Hannibal's Carthaginian armies had marauded Italy for more than a dozen years, threatening the very existence of the Roman republic. After witnessing a frightening meteor shower, the Roman magistrates consulted the Sibylline books, which prophesied that Hannibal could be defeated if the Idaean Mother was brought to Rome. This 'Mother,' a large, conical meteorite thought to represent the Great Mother of Gods, was enshrined in a temple at Pessinus in central Turkey.
The resplendent Roman delegation that was sent to King Attalus gained permission to remove the meteorite only after an earthquake changed the monarch's mind. A sacred ship was built and the meteorite sailed up the Tiber River to Rome. The leading citizen in the city performed the rituals of hospitality for the rock, then a procession carried it to the Temple of Victory. With this divine morale boost, the Romans expelled Hannibal from Italy within the year and soon conquered Carthage. In gratitude, the Romans built a special temple on the Palatine hill where the meteorite was worshipped for at least 500 years. However, the stone eventually fell into oblivion. 1730 it was apparently excavated from its chapel, only to be discarded for lack of recognition.

One such sacred rock was uncovered in 1808, when a party of explorers found a 1,635-pound hunk of metal near the Red River in central Texas. The Pawnee Indians had worshipped this meteorite for its curing powers and made regular pilgrimages to its site.
The explorers, who thought the metal was platinum, returned to the city to get provisions and equipment. They eventually split into two rival groups as they tried to outrace one another in cashing in on the treasure. The first party, which had left hastily without the gear for transporting the hefty load, could only hide the 'platinum' under a flat stone for safekeeping while they searched for horses. It took several days for the second party to find the prize and drag it toward the Red River. In their long overland journey they were repeatedly attacked by the desperate Indians.
The meteorite was transported by boat down the river to New Orleans, and finally to New York. There, Benjamin Silliman of Yale University recognized its true nature based on its high nickel content, after which the disappointed owners sold the object to Colonel George Gibbs.
After Gibbs' death in 1833 his wife rescued the meteorite from Irish laborers seeking to bury it; she then donated the rock to Yale as the largest meteorite in any collection at the time. Courtesy the Dutch Meteor Society.
Roman God Sol Invictus
In 1853 a meteorite that fell in eastern Africa just north of Zanzibar was declared to be a god by the Wanika tribe until famine and a massacre by the Masai rendered its owners skeptical of its powers. On December 2, 1880, a 6-pound meteorite fell at the feet of two Brahmins near Andhra, India, who immediately proclaimed themselves as ministers of the 'Miraculous God' and attracted up to 10,000 pilgrims a day. On August 14, 1992, dozens of rocks fell on the African town of Mbale in Uganda ( Sky & Telescope: June 1993, page 96). Local residents ground up some of the fragments and ingested the powder as medicine. They believed the rocks had been sent by their god to cure AIDS. It's easy to understand that a fiery descent from heaven can be interpreted as a god, or a god's gift, come to Earth.
The black Stone of Emesa The slow fall of the Roman empire was a chaotic drama in which a wide variety of religions coexisted and competed, often with the emperor's worship playing a key role. In addition to the traditional Roman pantheon, gods with Greek, Hebrew, and Egyptian origins enjoyed widespread followings. In this marathon of competing faiths a steady front-runner was the Sun god, variously called Apollo, Helios, Sol, Sol Invictus, or Elagabalus. The overwhelming power and importance of our day star makes a Sun god a natural chief deity; its worship is deeply embedded in many societies.
The cult of the Syrian Sun god Elagabalus was known in Rome from before the time of Julius Caesar, but it only came to dominance with the ascension of the Roman emperor Marcus Aurelius Antoninus. This silver coin was struck in A.D.
218-219 in honor of the young Roman emperor Marcus Aurelius Antoninus, who adopted the name of the Sun god Elagabalus. Antoninus was the high priest of the cult that worshiped the Black Stone of Emesa, which is believed to be a large meteorite. Shown here are four horses pulling the ceremonial chariot that carried the stone (behind the eagle).
The emperor led the procession to Rome while walking backward to keep his face toward his god. The inscription SANCT(O) DEO SOLI ELAGABAL(O) means 'To the holy god, the sun Elagabalus.'

He took his religious duties very seriously and even changed his name to that of his god, Elagabalus. The worship of Elagabalus was centered on the Black Stone of Emesa, a large, cone-shaped meteorite. When its high priest moved to Rome the stone came with him. Two magnificent temples were built for it, one on the Palatine hill and the other in the suburbs. The emperor personally led daily worship of the meteorite while dressed in silk robes, a lofty tiara, and cheeks painted red and white. Meteorite worship became the official religion of the Roman empire.
Elagabalus's cruelty, extravagance, neglect, and depravity quickly alienated him from all segments of society, so he was doomed to a short reign. On March 6, 222, at age 18, the emperor and his mother were assassinated by the Praetorian Guards, and their mutilated corpses were dragged through the streets of Rome. As for the meteorite, it was quietly returned to Syria and reinstalled in the temple of Emesa.
The rock was likely broken into pieces when the temple was converted to a Christian church sometime in the 4th century. The site, now a mosque, has never been excavated. Even after the disastrous reign of Elagabalus, the Sun god remained as the most important deity.
Many cities throughout the empire had instituted games in its honor by 240. The emperor Aurelian elevated Sol to the highest rank among all gods in 274, and this practice was followed by all rulers until the time of Constantine, who reigned from 306 to 337. Even Constantine wavered between Sol and Christ, and his coins celebrated the Sun god as the grantor of imperial power as late as 324, after which he converted both himself and his empire to Christianity. The spread of Christianity throughout Europe occurred for many reasons; still, it is amusing to wonder if it was only by the whim of an emperor that the western world now is predominantly Christian instead of meteorite-worshipping.
The Black Stone of the Kaaba The most famous sacred meteorite is the Black Stone of the Kaaba. The Kaaba is a cubical building in Mecca toward which Moslems pray five times daily. The Black Stone, set in the northeastern outside corner of the Kaaba, is considered to be the most sacred treasure of Islam.
The Kaaba also served as a center of worship for pre-Islamic Arabs and was reputed to contain 360 idols. In 630 the triumphant prophet Mohammed returned to Mecca and cleansed the temple of the idols after honoring the Black Stone. The heretical Qarmatian sect stole the stone in 930, but it was recovered 21 years later with positive identification provided by the stone's ability to float on water. In 1050 a mad Egyptian caliph sent a man to destroy the relic. The Kaaba was twice burned down and was flooded in 1626.
During these trials the original stone was broken up into about 15 pieces. It was finally set in cement surrounded by a silver frame. In the middle of Mecca's Grand Mosque is the black, cubic shrine of the Kaaba, the 'House of God,' which was said to have been built by Abraham (Ibrahim). On one corner of the Kaaba is the Black Stone, which is believed to be of meteoric origin. The exposed surface of the stone is roughly 6½ by 8 inches and is framed with a silver band. Here pilgrims can touch and kiss the Black Stone.
Some suggest that the object is not really a meteorite but may be impact glass, perhaps from the meteor craters at Wabar, 670 miles east of Mecca. Courtesy NASA & Hubble Space Telescope Comet Team. The collision of in July 1994 was a widely publicized event. Most of the educated population in the world heard about the dark impact scars on the Jovian atmosphere, each larger than Earth. If such a comet were to hit Earth, mass extinction would be the most likely scenario. The moral of the Amazonian, Tunguska, and Shoemaker-Levy 9 events is that such occurrences are not unique even in modern times.
Sol Invictus Band
Collisions of catastrophic proportions and worldwide scale can happen anytime within our lifetimes. Over the last decade or so, there has been a big change of consciousness among both scientists and the general public. The paradigm now is the realization that the Earth is a target in a giant shooting gallery, with the stakes as large as civilization itself. Countless articles, books, and movies on the threat of meteorite impacts have already appeared ( Sky & Telescope: June 1998, page 26). Thankfully, the larger the explosion, the rarer the event. Metropolis destroyers, with an explosive energy on the order of 100 million tons of TNT, happen roughly once per millennium.
Regional destroyers, about 100 billion tons of TNT, have an event rate of around once per hundred millennia. Civilization destroyers, about 100 trillion tons of TNT, average once every 10 million years or so. Astronomical events have changed history and affected the lives of ordinary people in a surprising number of ways, but only meteorites actually come down to Earth.
Constantine And Sol Invictus
They have had a great impact on humanity — as a resource for building civilization, as a god come to ground, and as the cause of mass die-offs. But as you are watching the fiery trails of Perseid or Leonid bolides, please remember only the majesty and not the terror.
