Commesso
Commesso, also referred to as Florentine mosaic, is a method of piecing together cut sections of luminous, narrow gemstones to form works of art.''Encyclopædia Britannica'' (1998). Art �"Commesso" Encyclopaedia Britannica, inc. Accessed March 03, 2017. Precise patterns are cut into a slab of (generally black) marble. Gems are then cautiously cut and meticulously inlaid into these patterns. The work is then polished section by section, as it cannot be polished as a whole due to gems having different hardnesses. The practice, which began in Florence, Italy, dates back to at least the 14th century and gained prominence just before the 17th century. Some of its uses include making pictures and decorating furniture and architecture.

Gemstones
A gemstone (also called a fine gem, jewel, precious stone, or semiprecious stone) is a piece of mineral crystal which, in cut and polished form, is used to make jewelry or other adornments. However, certain rocks (such as lapis lazuli, opal, and obsidian) and occasionally organic materials that are not minerals (such as amber, jet, and pearl) are also 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 physical properties that have aesthetic value. Rarity and notoriety are other characteristics that lend value to gemstones. Apart from jewelry, from earliest antiquity engraved gems and hardstone carvings, such as cups, were major luxury art forms. A gem expert is a gemologist, a gem maker is called a lapidarist or gemcutter; a diamond cutter is called a diamantaire.

Encyclopaedia Britannica, Inc
An encyclopedia (American English) or encyclopædia (British English) is a reference work or compendium providing summaries of knowledge either general or special to a particular field or discipline. Encyclopedias are divided into articles or entries that are arranged alphabetically by article name or by thematic categories, or else are hyperlinked and searchable. Encyclopedia entries are longer and more detailed than those in most dictionaries. Generally speaking, encyclopedia articles focus on '' factual information'' concerning the subject named in the article's title; this is unlike dictionary entries, which focus on linguistic information about words, such as their etymology, meaning, pronunciation, use, and grammatical forms.Béjoint, Henri (2000)''Modern Lexicography'', pp. 30–31. Oxford University Press. Encyclopedias have existed for around 2,000 years and have evolved considerably during that time as regards language (written in a major international or a verna ...

Marble
Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated (layered), although there are exceptions. In geology, the term ''marble'' refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. Etymology The word "marble" derives from the Ancient Greek (), from (), "crystalline rock, shining stone", perhaps from the verb (), "to flash, sparkle, gleam"; R. S. P. Beekes has suggested that a " Pre-Greek origin is probable". This stem is also the ancestor of the English word "marmoreal," meaning "marble-like." While the English term "marble" resembles the French , most other European languages (with words like "marmoreal") more closely resemble the original Ancient Greek. Physical origins Marble is a rock resulting from metamorphism of sedimentary carbonate ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polishing
Polishing is the process of creating a smooth and shiny surface by rubbing it or by applying a chemical treatment, leaving a clean surface with a significant specular reflection (still limited by the index of refraction of the material according to the Fresnel equations). In some materials (such as metals, glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal values. When an unpolished surface is magnified thousands of times, it usually looks like a succession of mountains and valleys. By repeated abrasion, those "mountains" are worn down until they are flat or just small "hills." The process of polishing with abrasives starts with a coarse grain size and gradually proceeds to the finer ones to efficiently flatten the surface imperfections and to obtain optimal results. Mechanical properties The strength of polished products can be higher than their unpolished counterparts owing to the removal of stress concentrations presen ...

Florence, Italy
Florence ( ; it, Firenze ) is a city in Central Italy and the capital city of the Tuscany region. It is the most populated city in Tuscany, with 383,083 inhabitants in 2016, and over 1,520,000 in its metropolitan area.Bilancio demografico anno 2013, datISTAT/ref> Florence was a centre of medieval European trade and finance and one of the wealthiest cities of that era. It is considered by many academics to have been the birthplace of the Renaissance, becoming a major artistic, cultural, commercial, political, economic and financial center. During this time, Florence rose to a position of enormous influence in Italy, Europe, and beyond. Its turbulent political history includes periods of rule by the powerful Medici family and numerous religious and republican revolutions. From 1865 to 1871 the city served as the capital of the Kingdom of Italy (established in 1861). The Florentine dialect forms the base of Standard Italian and it became the language of culture throughout Ita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosaic
A mosaic is a pattern or image made of small regular or irregular pieces of colored stone, glass or ceramic, held in place by plaster/mortar, and covering a surface. Mosaics are often used as floor and wall decoration, and were particularly popular in the Ancient Roman world. Mosaic today includes not just murals and pavements, but also artwork, hobby crafts, and industrial and construction forms. Mosaics have a long history, starting in Mesopotamia in the 3rd millennium BC. Pebble mosaics were made in Tiryns in Mycenean Greece; mosaics with patterns and pictures became widespread in classical times, both in Ancient Greece and Ancient Rome. Early Christian basilicas from the 4th century onwards were decorated with wall and ceiling mosaics. Mosaic art flourished in the Byzantine Empire from the 6th to the 15th centuries; that tradition was adopted by the Norman Kingdom of Sicily in the 12th century, by the eastern-influenced Republic of Venice, and among the Rus. Mosaic fell ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Florentine Painting
Florentine painting or the Florentine School refers to artists in, from, or influenced by the naturalistic style developed in Florence in the 14th century, largely through the efforts of Giotto di Bondone, and in the 15th century the leading school of Western painting. Some of the best known painters of the earlier Florentine School are Fra Angelico, Botticelli, Filippo Lippi, the Ghirlandaio family, Masolino, and Masaccio. Florence was the birthplace of the High Renaissance, but in the early 16th century the most important artists, including Michelangelo and Raphael were attracted to Rome, where the largest commissions then were. In part this was following the Medici, some of whom became cardinals and even the pope. A similar process affected later Florentine artists. By the Baroque period, the many painters working in Florence were rarely major figures. Before 1400 The earliest distinctive Tuscan art, produced in the 13th century in Pisa and Lucca, formed the basis for la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Italian Art
Since ancient times, Greeks, Etruscans and Celts have inhabited the south, centre and north of the Italian peninsula respectively. The very numerous rock drawings in Valcamonica are as old as 8,000 BC, and there are rich remains of Etruscan art from thousands of tombs, as well as rich remains from the Greek colonies at Paestum, Agrigento and elsewhere. Ancient Rome finally emerged as the dominant Italian and European power. The Roman remains in Italy are of extraordinary richness, from the grand Imperial monuments of Rome itself to the survival of exceptionally preserved ordinary buildings in Pompeii and neighbouring sites. Following the fall of the Roman Empire, in the Middle Ages Italy, especially the north, remained an important centre, not only of the Carolingian art and Ottonian art of the Holy Roman Emperors, but for the Byzantine art of Ravenna and other sites. Italy was the main centre of artistic developments throughout the Renaissance (1300-1600), beginning with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
