Onyx is the parallel-banded variety of chalcedony , a silicate mineral . Agate and onyx are both varieties of layered chalcedony that differ only in the form of the bands. Onyx has parallel bands, while agate has curved bands. The colors of its bands range from black to almost every color. Specimens of onyx commonly contain bands of black or white or both. Onyx, as a descriptive term, has also been applied to parallel-banded varieties of alabaster , marble , calcite , obsidian , and opal , and misleadingly to materials with contorted banding, such as "cave onyx" and "Mexican onyx".

35-580: Onyx comes through Latin (of the same spelling), from the Ancient Greek ὄνυξ ( onyx ), meaning ' claw ' or ' fingernail ' . Onyx with pink and white bands can sometimes resemble a fingernail. The English word "nail" is cognate with the Greek word. Onyx is formed of chalcedony bands in alternating colors. It is cryptocrystalline , consisting of fine intergrowths of the silica minerals quartz and moganite . Its bands are parallel, unlike

70-621: A common origin, but which in fact do not. For example, Latin habēre and German haben both mean 'to have' and are phonetically similar. However, the words evolved from different Proto-Indo-European (PIE) roots: haben , like English have , comes from PIE *kh₂pyé- 'to grasp', and has the Latin cognate capere 'to seize, grasp, capture'. Habēre , on the other hand, is from PIE *gʰabʰ 'to give, to receive', and hence cognate with English give and German geben . Likewise, English much and Spanish mucho look similar and have

105-401: A firm working on high-rise and underground construction, and it became the third firm to work on the building. During 2009 foundation work was completed. Valery Gutovsky, a specialist in high-rise and underground construction, became the new head of construction for the project., and on 29 May Vladimir Putin held a meeting at which he confirmed that the building would be completed in 2011 at

140-583: A long history of use for hardstone carving and jewelry , where it is usually cut as a cabochon or into beads. It has also been used for intaglio and hardstone cameo engraved gems , where the bands make the image contrast with the ground. Some onyx is natural but much of the material in commerce is produced by the staining of agate. Onyx was used in Egypt as early as the Second Dynasty to make bowls and other pottery items. Use of sardonyx appears in

175-577: A much-publicised contest for his design for a new home for the theatre, which is to be located adjacent to the current building. At the same time, the historic original structure had been due to undergo a complete renovation and this was planned to begin in the Autumn 2006. After seeing projected costs rise to $ 244 million (U.S.) from $ 100 million, the Russian government announced in November 2008 that it

210-563: A shimmering semi-translucent interior wall. The Hôtel de la Païva in Paris is noted for its yellow onyx décor, and the new Mariinsky Theatre Second Stage in St.Petersburg uses yellow onyx in the lobby. The ancient Romans entered battle carrying amulets of sardonyx engraved with Mars , the god of war. This was believed to bestow courage in battle. In Renaissance Europe, wearing sardonyx was believed to bestow eloquence. A traditional Persian belief

245-412: A similar meaning, but are not cognates: much is from Proto-Germanic *mikilaz < PIE *meǵ- and mucho is from Latin multum < PIE *mel- . A true cognate of much is the archaic Spanish maño 'big'. Cognates are distinguished from other kinds of relationships. An etymon , or ancestor word, is the ultimate source word from which one or more cognates derive. In other words, it

280-858: A tense situation and we didn't want to delay forever ... no one felt like it was the best way to simply sit down quietly and say, 'You are a great architect; just come and do it,'" Mr. Gergiev explained. With a budget of €295-million (about US $ 452-million), all of which will be paid by the Russian government with a completion date of no later than December 2011, the Canadian firm, Diamond and Schmitt Architects , prevailed over four other finalists, one of which came from Germany and three from Russia. The building has been hyped as "Russia's most important building project in 70 years". As noted by Mr. Diamond, (it is) "the first major opera house to be built in Russia since

315-565: Is artificially treated. In addition to dye treatments, heating and treatment with nitric acid have been used to lighten or eliminate undesirable colors. Onyx can be found in various regions of the world, including Greece, Yemen, Uruguay, Argentina, Australia, Brazil, Canada, China, Czech Republic, Germany, Pakistan, India, Indonesia, Madagascar, Latin America, the UK, and various states in the US. It has

350-795: Is mentioned in the Bible many times. Sardonyx (onyx in which white layers alternate with sard - a brownish color) is mentioned in the Bible as well. Onyx was known to the Ancient Greeks and Romans . The first-century naturalist Pliny the Elder described both types of onyx and various artificial treatment techniques in his Naturalis Historia . Slabs of onyx (from the Atlas Mountains ) were famously used by Mies van der Rohe in Villa Tugendhat at Brno (completed 1930) to create

385-492: Is regular. Paradigms of conjugations or declensions, the correspondence of which cannot be generally due to chance, have often been used in cognacy assessment. However, beyond paradigms, morphosyntax is often excluded in the assessment of cognacy between words, mainly because structures are usually seen as more subject to borrowing. Still, very complex, non-trivial morphosyntactic structures can rarely take precedence over phonetic shapes to indicate cognates. For instance, Tangut ,

420-426: Is that it helped with epilepsy . Sardonyx was traditionally used by English midwives to ease childbirth by laying it between the breasts of the mother. Cognate In historical linguistics , cognates or lexical cognates are sets of words that have been inherited in direct descent from an etymological ancestor in a common parent language . Because language change can have radical effects on both

455-482: Is the second part of a theatre complex which is made up of the original 1860 Mariinsky Theatre and the 2007 Mariinsky Theatre Concert Hall. The Second Stage has been completed and a gala concert celebrating the opening, and featuring performers Plácido Domingo , Rene Pape and Anna Netrebko , was presented on 2 May 2013. The concert also celebrated the sixtieth birthday of musical director Valery Gergiev . The post-modernist French architect Dominique Perrault won

490-483: Is the source of related words in different languages. For example, the etymon of both Welsh ceffyl and Irish capall is the Proto-Celtic * kaballos (all meaning horse ). Descendants are words inherited across a language barrier, coming from a particular etymon in an ancestor language. For example, Russian мо́ре and Polish morze are both descendants of Proto-Slavic * moře (meaning sea ). A root

525-444: Is the source of related words within a single language (no language barrier is crossed). Similar to the distinction between etymon and root , a nuanced distinction can sometimes be made between a descendant and a derivative . A derivative is one of the words which have their source in a root word, and were at some time created from the root word using morphological constructs such as suffixes, prefixes, and slight changes to

560-820: The Paraguayan Guarani panambi , the Eastern Bolivian Guarani panapana , the Cocama and Omagua panama , and the Sirionó ana ana are cognates, derived from the Old Tupi panapana , 'butterfly', maintaining their original meaning in these Tupi languages . Cognates need not have the same meaning, as they may have undergone semantic change as the languages developed independently. For example English starve and Dutch sterven 'to die' or German sterben 'to die' all descend from

595-656: The Czars." At the end of the design competition for The Second Stage of the Mariinsky Theater in 2003, 11 proposals had been received. The winner was well-known French architect Dominique Perrault with «a gold cocoon» (an external cover of a building of the wrong form from glass and aluminium ). By 2005 experts discovered that detailed proposals presented by the competition winner did not meet Russian building codes . They failed to include sections relating to water supply , drainage, and ventilation . The result

630-453: The Elder described these techniques used in Roman times. Treatments for producing black and other colors include soaking or boiling chalcedony in sugar solutions, then treating with sulfuric or hydrochloric acid to carbonize sugars which had been absorbed into the top layers of the stone. These techniques are still used, as well as other dyeing treatments, and most so-called "black onyx" sold

665-740: The Proto-Indo-European *nókʷts 'night'. The Indo-European languages have hundreds of such cognate sets, though few of them are as neat as this. The Arabic سلام salām , the Hebrew שלום ‎ shalom , the Assyrian Neo-Aramaic shlama and the Amharic selam 'peace' are cognates, derived from the Proto-Semitic *šalām- 'peace'. The Brazilian Portuguese panapanã , (flock of butterflies in flight),

700-521: The art of Minoan Crete , notably from the archaeological recoveries at Knossos . Brazilian green onyx was often used as plinths for art deco sculptures created in the 1920s and 1930s. The German sculptor Ferdinand Preiss used Brazilian green onyx for the base on the majority of his chryselephantine sculptures. Green onyx was also used for trays and pin dishes – produced mainly in Austria – often with small bronze animals or figures attached. Onyx

735-439: The builders strengthened the consistency of the soil to a depth of 12 to 14 metres and, as a result, cost estimates had to be increased. Moreover, the builders informed the authorities that the construction of a glass dome, as planned by Dominique Perrault's architectural firm, was impossible. Therefore that part of the project would have to be changed. By June, the project had a new local architect partner, KB ViPS Architects ,

770-403: The cost estimated in the published budget. On 28 July, the result of the last competition was announced, the winner being KB ViPS Architects , a specialist in high-rise and underground construction. Within a month, a contract was signed with that company and construction proceeded, with some parts of the building then reaching a height 5 metres. At the same time, according to Valery Gutovsky,

805-431: The existing city environment", Gergiev said. The height of the building was reduced and other elements were also reconsidered. In 2008 the foundation work for the building of the theatre continued, but by April, it was found that the consistency of the soil under the construction area was unpredictable. (Later builders have compared the properties of the soil to those of sour cream ). In order to overcome these problems,

840-532: The language of the Xixia Empire, and one Horpa language spoken today in Sichuan , Geshiza, both display a verbal alternation indicating tense, obeying the same morphosyntactic collocational restrictions. Even without regular phonetic correspondences between the stems of the two languages, the cognatic structures indicate secondary cognacy for the stems. False cognates are pairs of words that appear to have

875-546: The market is artificially colored. The name has also commonly been used to label other banded materials, such as banded calcite found in Mexico , India , and other places, and often carved, polished, and sold. This material is much softer than true onyx and more readily available. The majority of carved items sold as "onyx" today are this carbonate material. Artificial onyx types have also been produced from common chalcedony and plain agates. The first-century naturalist Pliny

910-414: The more chaotic banding that often occurs in agates . Sardonyx is a variant in which the colored bands are sard ( shades of red ) rather than black. Black onyx is perhaps the most famous variety, but it is not as common as onyx with colored bands. Artificial treatments have been used since ancient times to produce the black color in "black onyx" and the reds and yellows in sardonyx. Most "black onyx" on

945-619: The project was to be submitted to the town-planning council of St. Petersburg in October 2009 and to Glavgosekspertiza ("The General State Expert Review Department of the State Committee for Construction, Housing and Utilities" which was authorized to perform the state expert review of all projects by spring 2010. The construction cost was estimated at 8.5 billion roubles. The theater has been described as too modern and not modern enough, too ambitious and too restrained. The theater

980-983: The same Indo-European root are: night ( English ), Nacht ( German ), nacht ( Dutch , Frisian ), nag ( Afrikaans ), Naach ( Colognian ), natt ( Swedish , Norwegian ), nat ( Danish ), nátt ( Faroese ), nótt ( Icelandic ), noc ( Czech , Slovak , Polish ), ночь, noch ( Russian ), ноќ, noć ( Macedonian ), нощ, nosht ( Bulgarian ), ніч , nich ( Ukrainian ), ноч , noch / noč ( Belarusian ), noč ( Slovene ), noć ( Serbo-Croatian ), nakts ( Latvian ), naktis ( Lithuanian ), nos ( Welsh/Cymraeg ), νύξ, nyx ( Ancient Greek ), νύχτα / nychta ( Modern Greek ), nakt- ( Sanskrit ), natë ( Albanian ), nox , gen. sg. noctis ( Latin ), nuit ( French ), noche ( Spanish ), nochi ( Extremaduran ), nueche ( Asturian ), noite ( Portuguese and Galician ), notte ( Italian ), nit ( Catalan ), nuet/nit/nueit ( Aragonese ), nuèch / nuèit ( Occitan ) and noapte ( Romanian ). These all mean 'night' and derive from

1015-457: The same Proto-Germanic verb, *sterbaną 'to die'. Cognates also do not need to look or sound similar: English father , French père , and Armenian հայր ( hayr ) all descend directly from Proto-Indo-European *ph₂tḗr . An extreme case is Armenian երկու ( erku ) and English two , which descend from Proto-Indo-European *dwóh₁ ; the sound change *dw > erk in Armenian

1050-442: The sound and the meaning of a word, cognates may not be obvious, and it often takes rigorous study of historical sources and the application of the comparative method to establish whether lexemes are cognate. Cognates are distinguished from loanwords , where a word has been borrowed from another language. The English term cognate derives from Latin cognatus , meaning "blood relative". An example of cognates from

1085-437: The vowels or to the consonants of the root word. For example unhappy , happily , and unhappily are all derivatives of the root word happy . The terms root and derivative are used in the analysis of morphological derivation within a language in studies that are not concerned with historical linguistics and that do not cross the language barrier.

The last architect Diamond Schmitt Architects finished the design by creating an onyx wall which is visible from outside and illuminated. The lobby has a modern style with several straight and spiral staircases with glass balustrades. For the glass stairs and balustrades Diamond Schmitt Architects co-operated with Malishev Engineers , who were instrumental in designing Award Winning structures, most notably 36m long structural glass stair (first use of structural glass in public building in Russia) and large 100t spiral staircase which

In particular, it was necessary to make changes – based on the Saint Petersburg climate – in order to strengthen load-bearing structures above which the gold cupola would be located. As a result, the building would not look so open to the air. By July, the project had been simplified as much as possible, and it was determined that it would "not intrude so much into

1190-597: Was killing the Perrault plan. The Russian Prime Minister Vladimir Putin overruled both Valery Gergiev (the artistic director of the Mariinsky Theatre) and the Minister for Culture, announcing in early June 2009 that there would be a new competition to solicit proposals. A total of 15 proposals were received, a list which was then shortened to five. "We wanted to give the impression that although we were in

However, in June of that year the new general contractor, "Joint-Stock Company "NPO" Georeconstruction-fundamentproekt", in a short space of time removed all 286 obstacles shown on the working drawings of Perrault . As had become clear, the winning design
