History Of Red
The color red is the longest wavelength of light discernable to the human eye, with a range of between 620 and 750 nanometers. Red was commonly the first color term added to languages after the colors of black and white. As well as this, the color was the first color to be used by humans. Because of this, certain languages used the word for the color red to simply be the word for any color visible to the human eye. The color red was commonly formed out of several materials, including iron, mercury, and lead (however mercury and lead paints were toxic). The color Red was used in several applications by humans, which early on included use in calligraphy and writing beginning in 8th century China as a way to mark underlines and draw attention to portions of a script. The color red also included a wide variety of different cultural meanings. Sometimes the color was a color of romance, while in other cases being the color of violence. In short, different cultures and regions applie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wavelength
In physics and mathematics, wavelength or spatial period of a wave or periodic function is the distance over which the wave's shape repeats. In other words, it is the distance between consecutive corresponding points of the same ''phase (waves), phase'' on the wave, such as two adjacent crests, troughs, or zero crossings. Wavelength is a characteristic of both traveling waves and standing waves, as well as other spatial wave patterns. The multiplicative inverse, inverse of the wavelength is called the ''spatial frequency''. Wavelength is commonly designated by the Greek letter lambda (''λ''). For a modulated wave, ''wavelength'' may refer to the carrier wavelength of the signal. The term ''wavelength'' may also apply to the repeating envelope (mathematics), envelope of modulated waves or waves formed by Interference (wave propagation), interference of several sinusoids. Assuming a sinusoidal wave moving at a fixed phase velocity, wave speed, wavelength is inversely proportion ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bible
The Bible is a collection of religious texts that are central to Christianity and Judaism, and esteemed in other Abrahamic religions such as Islam. The Bible is an anthology (a compilation of texts of a variety of forms) originally written in Hebrew, Aramaic, and Koine Greek. The texts include instructions, stories, poetry, prophecies, and other genres. The collection of materials accepted as part of the Bible by a particular religious tradition or community is called a biblical canon. Believers generally consider it to be a product of divine inspiration, but the way they understand what that means and interpret the text varies. The religious texts were compiled by different religious communities into various official collections. The earliest contained the first five books of the Bible, called the Torah in Hebrew and the Pentateuch (meaning 'five books') in Greek. The second-oldest part was a collection of narrative histories and prophecies (the Nevi'im). The third co ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Armenian Cochineal
The Armenian cochineal (''Porphyrophora hamelii''), also known as the Ararat cochineal or Ararat scale, is a scale insect indigenous to the Ararat plain and Aras (Araks) River valley in the Armenian Highlands, including East of Turkey. It was formerly used to produce an eponymous crimson carmine dyestuff known in Armenia as ''vordan karmir'' (, literally "worm's red") and historically in Persia as ''kirmiz''. Vedeler, citing Cardon (2007), notes that "the Persian name ''Kirmiz'' originally referred to the Armenian carmine, a parasitic insect living on Gramineae grass, but the same name was also used by Arab geographers for insects living on oak trees in Maghreb and Al-Andalus, probably referring to '' Kermes vermilio''", although " is ... not clear whether the 'Kirmiz' dyestuff mentioned in early Arab texts always refers to the use of the insect ''Kermes Vermilio''."

Kermes Oak
''Quercus coccifera'', the kermes oak or commonly known as Palestine oak, is an oak shrub or tree in section '' Ilex'' of the genus. It has many synonyms, including ''Quercus calliprinos''. It is native to the Mediterranean region and Northern African Maghreb, south to north from Morocco to France and west to east from Portugal to Cyprus and Turkey, crossing Spain, Italy, Libya, the Balkans, and Greece, including Crete. The Kermes oak was historically important as the food plant of '' Kermes'' scale insects, from which a red dye called crimson was obtained. The etymology of the specific name ''coccifera'' is related to the production of red cochineal (crimson) dye and derived from Latin coccum which was from Greek κόκκος, the kermes insect. The Latin -fera means 'bearer'. Description ''Quercus coccifera'' is usually a shrub less than high, rarely a small tree, reaching tall (with specimens recorded in Kouf, Libya).

Kermes Vermilio
''Kermes vermilio'' is a species of '' Kermes'' that feeds on trees. Some of the species are used to make vermilion; though a mineral form used in many cultures and discovered at a similar time is cinnabar (crystallized HgS, mercury sulfide). For details of further chemical alternatives see vermilion.

Kermes (insect)
''Kermes'' is a genus of gall-like scale insects in the family Kermesidae. They feed on the sap of oaks; the females produce a red dye, also called " kermes", that is the source of natural crimson. The word "kermes" is derived from Turkish ''qirmiz'' or ''kirmizi'' ( قرمز), "crimson" (both the colour and the dyestuff), itself deriving from Persian *کرمست (*kermest) via Proto-Indo-Iranian *kŕ̥miš, from Proto-Indo-European *kʷŕ̥mis (“worm”). The first instars are called "crawlers". They are less than long, salmon-colored, and wingless with well-developed legs. As adults, they demonstrate significant sexual dimorphism. Males are gnat-like with fragile wings, while females are bulbous with reduced legs and antennas, and are easily mistaken for buds or gall Galls (from the Latin , 'oak-apple') or ''cecidia'' (from the Greek , anything gushing out) are a kind of swelling growth on the external tissues of plants.

Scale Insect
Scale insects are small insects of the Order (biology), order Hemiptera, suborder Sternorrhyncha. Of dramatically variable appearance and extreme sexual dimorphism, they comprise the infraorder Coccomorpha which is considered a more convenient grouping than the superfamily Coccoidea due to taxonomic uncertainties. Adult females typically have soft bodies and no limbs, and are concealed underneath domed scales, extruding quantities of wax for protection. Some species are hermaphroditic, with a combined ovotestis instead of separate ovaries and testes. Males, in the species where they occur, have legs and sometimes wings, and resemble small flies. Scale insects are herbivores, piercing plant tissues with their mouthparts and remaining in one place, feeding on sap. The excess fluid they imbibe is secreted as Honeydew (secretion), honeydew on which sooty mold tends to grow. The insects often have a Mutualism (biology), mutualistic relationship with ants, which feed on the honeydew and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neolithic Period
The Neolithic or New Stone Age (from Greek 'new' and 'stone') is an archaeological period, the final division of the Stone Age in Mesopotamia, Asia, Europe and Africa (c. 10,000 BCE to c. 2,000 BCE). It saw the Neolithic Revolution, a wide-ranging set of developments that appear to have arisen independently in several parts of the world. This "Neolithic package" included the introduction of farming, domestication of animals, and change from a hunter-gatherer lifestyle to one of settlement. The term 'Neolithic' was coined by Sir John Lubbock in 1865 as a refinement of the three-age system. The Neolithic began about 12,000 years ago, when farming appeared in the Epipalaeolithic Near East and Mesopotamia, and later in other parts of the world. It lasted in the Near East until the transitional period of the Chalcolithic (Copper Age) from about 6,500 years ago (4500 BCE), marked by the development of metallurgy, leading up to the Bronze Age and Iron Age. In other places, th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kermes (dye)
Kermes is a red dye derived from the dried bodies of the females of a scale insect in the genus '' Kermes'', primarily '' Kermes vermilio''. The ''Kermes'' insects are native in the Mediterranean region and are parasites living on the sap of the host plant, the Kermes oak (''Quercus coccifera'') and the Palestine oak (''Quercus calliprinos''). Amar, ''et al''. (2005), p. 1081 These insects were used as a red dye since antiquity by the ancient Egyptians, Mesopotamians, Indians, Greeks, Romans, and Iranians. The dye also served a number of ritual and practical purposes in the Hebrew Bible. The kermes dye is a rich red, a crimson. It has good colour fastness in silk and wool. It was much esteemed in the medieval era for dyeing silk and wool, particularly scarlet cloth. Following the Columbian exchange it was superseded by the similar, and more easily obtained, cochineal. Etymology Kermes ultimately derives from the Sanskrit word कृमिज or ''kṛmija'' meaning "worm- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cave Of Altamira
The Cave of Altamira ( ; ) is a cave complex, located near the historic town of Santillana del Mar in Cantabria, Spain. It is renowned for prehistoric cave painting, cave art featuring charcoal drawings and polychrome paintings of contemporary local fauna and human hands. The earliest paintings were applied during the Upper Paleolithic, around 36,000 years ago. The site was discovered in 1868 by Modesto Cubillas and subsequently studied by Marcelino Sanz de Sautuola. Aside from the striking quality of its polychromatic art, Altamira's fame stems from the fact that its paintings were the first European cave paintings for which a prehistoric origin was suggested and promoted. Sautuola published his research with the support of Juan de Vilanova y Piera in 1880, to initial public acclaim. However, the publication of Sanz de Sautuola's research quickly led to a bitter public controversy among experts, some of whom rejected the prehistoric origin of the paintings on the grounds that ...
