Gemstone
–
A gemstone is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks or organic materials that are not minerals are used for jewelry and are therefore often considered to be gemstones as well. Most gemstones are hard, but some soft minerals are used in jewelry because of their luster or other properties that have aesthetic value. Rarity is another characteristic that lends value to a gemstone, apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem maker is called a lapidary or gemcutter, a worker is a diamantaire. The carvings of Carl Fabergé are significant works in this tradition, the traditional classification in the West, which goes back to the ancient Greeks, begins with a distinction between precious and semi-precious, similar distinctions are made in other cultures. In modern usage the precious stones are diamond, ruby, sapphire, other stones are classified by their color, translucency and hardness. Another unscientific term for semi-precious gemstones used in art history and archaeology is hardstone, in modern times gemstones are identified by gemologists, who describe gems and their characteristics using technical terminology specific to the field of gemology. The first characteristic a gemologist uses to identify a gemstone is its chemical composition, for example, diamonds are made of carbon and rubies of aluminium oxide. Next, many gems are crystals which are classified by their crystal system such as cubic or trigonal or monoclinic, another term used is habit, the form the gem is usually found in. For example, diamonds, which have a crystal system, are often found as octahedrons. Gemstones are classified into different groups, species, and varieties, for example, ruby is the red variety of the species corundum, while any other color of corundum is considered sapphire. Other examples are the Emerald, aquamarine, red beryl, goshenite, heliodor, and morganite, gems are characterized in terms of refractive index, dispersion, specific gravity, hardness, cleavage, fracture, and luster. They may exhibit pleochroism or double refraction and they may have luminescence and a distinctive absorption spectrum. Material or flaws within a stone may be present as inclusions, gemstones may also be classified in terms of their water. This is a grading of the gems luster, transparency. Very transparent gems are considered first water, while second or third water gems are those of a lesser transparency, there is no universally accepted grading system for gemstones. Diamonds are graded using a system developed by the Gemological Institute of America in the early 1950s, historically, all gemstones were graded using the naked eye

Josephus
–
Josephus claimed the Jewish Messianic prophecies that initiated the First Roman-Jewish War made reference to Vespasian becoming Emperor of Rome. In response Vespasian decided to keep Josephus as a slave and interpreter, after Vespasian became Emperor in 69 CE, he granted Josephus his freedom, at which time Josephus assumed the emperors family name of Flavius. Flavius Josephus fully defected to the Roman side and was granted Roman citizenship and he became an advisor and friend of Vespasians son Titus, serving as his translator when Titus led the Siege of Jerusalem. Since the siege proved ineffective at stopping the Jewish revolt, the citys destruction, Josephus recorded Jewish history, with special emphasis on the first century CE and the First Jewish–Roman War, including the Siege of Masada. His most important works were The Jewish War and Antiquities of the Jews, the Jewish War recounts the Jewish revolt against Roman occupation. Antiquities of the Jews recounts the history of the world from a Jewish perspective for an ostensibly Roman audience and these works provide valuable insight into first century Judaism and the background of Early Christianity. Josephus introduces himself in Greek as Iōsēpos, son of Matthias and he was the second-born son of Matthias. His older full-blooded brother was also called Matthias and their mother was an aristocratic woman who descended from the royal and formerly ruling Hasmonean dynasty. Josephuss paternal grandparents were Josephus and his wife—an unnamed Hebrew noblewoman, distant relatives of each other and he descended through his father from the priestly order of the Jehoiarib, which was the first of the 24 orders of priests in the Temple in Jerusalem. Josephus was a descendant of the high priest Jonathon, born and raised in Jerusalem, Josephus was educated alongside his brother. In his early twenties, he traveled to negotiate with Emperor Nero for the release of 12 Jewish priests, Josephus successfully fought the Roman army in Galilee, until he was captured by the Romans during the height of the war. After the Jewish garrison of Yodfat fell under siege, the Romans invaded, killing thousands, according to Josephus, he was trapped in a cave with 40 of his companions in July 67 CE. The Romans asked the group to surrender, but they refused, Josephus suggested a method of collective suicide, they drew lots and killed each other, one by one, counting to every third person. Two men were left, who surrendered to the Roman forces, in 69 CE, Josephus was released. According to his account, he acted as a negotiator with the defenders during the Siege of Jerusalem in 70 CE, in which his parents and first wife died. While being confined at Yodfat, Josephus claimed to have experienced a divine revelation, after the prediction came true, he was released by Vespasian, who considered his gift of prophecy to be divine. In 71 CE, he went to Rome in the entourage of Titus, becoming a Roman citizen, in addition to Roman citizenship, he was granted accommodation in conquered Judaea and a decent, if not extravagant, pension. While in Rome and under Flavian patronage, Josephus wrote all of his known works, although he uses Josephus, he appears to have taken the Roman praenomen Titus and nomen Flavius from his patrons

Book of Exodus
–
The Book of Exodus or, simply, Exodus, is the second book of the Torah and the Hebrew Bible. The book tells how the Israelites leave slavery in Egypt through the strength of Yahweh, led by their prophet Moses they journey through the wilderness to Mount Sinai, where Yahweh promises them the land of Canaan in return for their faithfulness. There is no agreement among scholars on the structure of Exodus. One strong possibility is that it is a diptych, with the division between parts 1 and 2 at the crossing of the Red Sea or at the beginning of the theophany in chapter 19. On this plan, the first part tells of Gods rescue of his people from Egypt and their journey under his care to Sinai, jacobs sons and their families join their brother, Joseph, in Egypt. Once there, the Israelites begin to grow in number, several generations later, Egypts Pharaoh, fearful that the Israelites could be a fifth column, orders that all newborn boys be thrown into the Nile. A Levite woman saves her baby by setting him adrift on the river Nile in an ark of bulrushes, the Pharaohs daughter finds the child, names him Moses, and brings him up as her own. But Moses is aware of his origins, and one day, there he marries Zipporah, the daughter of Midianite priest Jethro, and encounters God in a burning bush. Moses asks God for his name, God replies, I AM that I AM, God tells Moses to return to Egypt and lead the Hebrews into Canaan, the land promised to Abraham. Moses returns to Egypt and fails to convince the Pharaoh to release the Israelites, God smites the Egyptians with 10 terrible plagues including a river of blood, many frogs, and the death of first-born sons. Moses leads the Israelites out of bondage after a chase when the Pharaoh reneges on his coerced consent. The desert proves arduous, and the Israelites complain and long for Egypt, the Israelites arrive at the mountain of God, where Moses father-in-law Jethro visits Moses, at his suggestion Moses appoints judges over Israel. God asks whether they agree to be his people. Moses is told to ascend the mountain, God pronounces the Ten Commandments in the hearing of all Israel. Moses goes up the mountain into the presence of God, who pronounces the Covenant Code, Moses comes down the mountain and writes down Gods words and the people agree to keep them. God calls Moses up the mountain where he remains for 40 days and 40 nights, at the conclusion of the 40 days and 40 nights, Moses returns holding the set of stone tablets. Aaron is appointed as the first hereditary high priest, God gives Moses the two tablets of stone containing the words of the ten commandments, written with the finger of God. While Moses is with God, Aaron makes a golden calf, God informs Moses of their apostasy and threatens to kill them all, but relents when Moses pleads for them

Zodiac
–
The zodiac is an area of the sky centered upon the ecliptic, the apparent path of the Sun across the celestial sphere over the course of the year. The paths of the Moon and visible planets also remain close to the ecliptic, within the belt of the zodiac, in western astrology and astronomy, the zodiac is divided into twelve signs, each sign occupying 30° of celestial longitude. Because the signs are regular, they do not correspond exactly to the boundaries of the twelve constellations after which they are named, the English word zodiac derives from zōdiacus, the Latinized form of the Ancient Greek zōidiakòs kýklos, meaning circle of little animals. Zōidion is the diminutive of zōion, the name reflects the prominence of animals among the twelve signs. The construction of the zodiac is described in Ptolemys vast 2nd century AD work, the term zodiac may also refer to the region of the celestial sphere encompassing the paths of the planets corresponding to the band of about eight arc degrees above and below the ecliptic. The zodiac of a planet is the band that contains the path of that particular body, e. g. the zodiac of the Moon is the band of five degrees above. By extension, the zodiac of the comets may refer to the band encompassing most short-period comets, the division of the ecliptic into the zodiacal signs originates in Babylonian astronomy during the first half of the 1st millennium BC. The zodiac draws on stars in earlier Babylonian star catalogues, such as the MUL. APIN catalogue, around the end of the 5th century BC, Babylonian astronomers divided the ecliptic into twelve equal signs, by analogy to twelve schematic months of thirty days each. Each sign contained thirty degrees of longitude, thus creating the first known celestial coordinate system. Because the division was made into equal arcs, 30° each, in Babylonian astronomical diaries, a planet position was generally given with respect to a zodiacal sign alone, less often in specific degrees within a sign. When the degrees of longitude were given, they were expressed with reference to the 30° of the zodiacal sign, in astronomical ephemerides, the positions of significant astronomical phenomena were computed in sexagesimal fractions of a degree. For daily ephemerides, the positions of a planet were not as important as the astrologically significant dates when the planet crossed from one zodiacal sign to the next. The Babylonian star catalogs entered Greek astronomy in the 4th century BC, Babylonia or Chaldea in the Hellenistic world came to be so identified with astrology that Chaldean wisdom became among Greeks and Romans the synonym of divination through the planets and stars. Hellenistic astrology derived in part from Babylonian and Egyptian astrology, horoscopic astrology first appeared in Ptolemaic Egypt. The Dendera zodiac, a dating to ca.50 BC, is the first known depiction of the classical zodiac of twelve signs. The earliest extant Greek text using the Babylonian division of the zodiac into 12 signs of 30 equal degrees each is the Anaphoricus of Hypsicles of Alexandria. Particularly important in the development of Western horoscopic astrology was the astrologer and astronomer Ptolemy, whose work Tetrabiblos laid the basis of the Western astrological tradition. Under the Greeks, and Ptolemy in particular, the planets, Houses, Ptolemy lived in the 2nd century AD, three centuries after the discovery of the precession of the equinoxes by Hipparchus around 130 BC

George Frederick Kunz
–
George Frederick Kunz was an American mineralogist and mineral collector. Kunz was born in New York City, USA, and began an interest in minerals at a young age. By his teens, he had amassed a collection of four thousand items. Kunz attended Cooper Union but did not finish and did not attend college, nonetheless, he taught himself mineralogy from books and field research. This expertise landed him a job with Tiffany & Co. and his knowledge and he gained much notoriety for identifying a new gem variety of the mineral spodumene which was named Kunzite in his honor. He headed up the US mining and mineralogical exhibits at the international expositions in Paris, Chicago, Atlanta, Paris and he gave a series of eight lectures on Precious Stones for the Lowell Institutes 1894-95 season. He also assembled the Morgan-Tiffany collection of gems in the American Museum of Natural History, Kunz had an active life dedicated to science and public service. Kunz promoted the adoption of the metric system of weights. He wrote over 300 articles during his life, almost eighty years after his death, many of his books are still in print. Kunz married Sophia Hanforth in 1879, who died in 1912, in 1923, Kunz married Opal Logan Giberson, a noted aviator, but the marriage was annulled in 1929. Nonetheless, Opal Kunz continued to maintain Kunzs household until his death and he was given many honorary degrees from US and European universities. He was awarded a Bachelor of Science degree from the Cooper Union in 1872, Columbia University The award was presented by Professor James F. Kemp, professor of Geology at Columbia, University of Marburg, especially for his contributions to European and German mineralogy. After his death, his collection of several thousand rare books, pamphlets and articles on gems. Acquired by the Library in 1933, the George F, in December 2012, the discovery of a rare photographic album dated 1922 among the books from Mr Kunz personal library was announced by the USGS. The album contained 81 photographs of the Russian Crown Jewels and pre-dates the official catalog by the Soviet government by 3 years, researchers have identified four pieces of jewelry that were documented in 1922 that were not included in the later catalog and that are assumed missing today.

Second Temple
–
The Second Temple was the Jewish Holy Temple which stood on the Temple Mount in Jerusalem during the Second Temple period, between 516 BCE and 70 CE. Jewish eschatology includes a belief that the Second Temple will be replaced by a future Third Temple, the accession of Cyrus the Great of the Persian Empire in 559 BCE made the re-establishment of the city of Jerusalem and the rebuilding of the Temple possible. According to the Bible, when the Jewish exiles returned to Jerusalem following a decree from Cyrus the Great, the events take place in the second half of the 5th century BCE. Listed together with the Book of Ezra as Ezra-Nehemiah, it represents the chapter in the historical narrative of the Hebrew Bible. The original core of the book, the memoir, may have been combined with the core of the Book of Ezra around 400 BCE. Further editing probably continued into the Hellenistic era, the book tells how Nehemiah, at the court of the king in Susa, is informed that Jerusalem is without walls and resolves to restore them. The king appoints him as governor of the province Yehud Medinata, there he rebuilds the walls, despite the opposition of Israels enemies, and reforms the community in conformity with the law of Moses. After 12 years in Jerusalem, he returns to Susa but subsequently revisits Jerusalem and he finds that the Israelites have been backsliding and taking non-Jewish wives, and he stays in Jerusalem to enforce the Law. A wide interest was felt in this movement, although it was regarded with mixed feelings by the spectators. The Samaritans made proposals for co-operation in the work, Zerubbabel and the elders, however, declined all such cooperation, feeling that the Jews must build the Temple without help. Immediately evil reports were spread regarding the Jews, according to Ezra 4,5, the Samaritans sought to frustrate their purpose and sent messengers to Ecbatana and Susa, with the result that the work was suspended. Seven years later, Cyrus the Great, who allowed the Jews to return to their homeland and rebuild the Temple, on his death, the false Smerdis, an impostor, occupied the throne for some seven or eight months, and then Darius became king. It was ready for consecration in the spring of 516 BCE, the Book of Haggai includes a prediction that the glory of the second temple would be greater than that of the first. Some of the artifacts from the Temple of Solomon are not mentioned in the sources after its destruction in 597 BCE. In the Second Temple, the Kodesh Hakodashim was separated by curtains rather than a wall as in the First Temple. Still, as in the Tabernacle, the Second Temple included, The Menorah for the Hekhal The Table of Showbread The golden altar of incense, with golden censers. According to the Mishnah, the Foundation Stone stood where the Ark used to be, the Second Temple also included many of the original vessels of gold that had been taken by the Babylonians but restored by Cyrus the Great. According to the Babylonian Talmud, however, the Temple lacked the Shekinah, the dwelling or settling divine presence of God, and the Ruach HaKodesh, judea became at that moment part of the Seleucid empire of Syria
