Information: - Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble may be foliated. Geologists use the term "marble" to refer to metamorphosed limestone; however, stonemasons use the term more broadly to encompass unmetamorphosed limestone. Marble is commonly used for sculpture and as a building material. - Calcite is a carbonate mineral and the most stable polymorph of calcium carbonate (CaCO). The Mohs scale of mineral hardness, based on scratch hardness comparison, defines value 3 as "calcite". - Niccolo dellArca (c. 1435-1440 2 March 1494) was an Italian Early Renaissance sculptor. He is also known under the names Niccolo da Ragusa, Niccolo da Bari and Niccolo d'Antonio d'Apulia. The surname dellArca refers to his contribution to the Arca di San Domenico. - Arnolfo di Cambio (c. 1240 1300/1310) was an Italian architect and sculptor. - Emilia-Romagna (, Romagnol: "Emelia-Rumagna") is an administrative Region of Northeast Italy, comprising the historical regions of Emilia and Romagna. Its capital is Bologna. It has an area of , and about 4.4 million inhabitants. - Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200C) and pressure (1500 bars), causing profound physical and/or chemical change. The protolith may be a sedimentary rock, an igneous rock or another older metamorphic rock. - The Basilica of San Domenico is one of the major churches in Bologna, Italy. The remains of Saint Dominic, founder of the Order of Preachers (Dominicans), are buried inside the exquisite shrine Arca di San Domenico, made by Nicola Pisano and his workshop, Arnolfo di Cambio and with later additions by Niccolo dell'Arca and the young Michelangelo. - Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally The term is also used for a sedimentary carbonate rock composed mostly of the mineral dolomite. An alternative name sometimes used for the dolomitic rock type is dolostone. - Michelangelo di Lodovico Buonarroti Simoni (6 March 1475 18 February 1564) was an Italian sculptor, painter, architect, and poet of the High Renaissance who exerted an unparalleled influence on the development of Western art. Considered to be the greatest living artist during his lifetime, he has since been described as one of the greatest artists of all time. Despite making few forays beyond the arts, his versatility in the disciplines he took up was of such a high order that he is often considered a contender for the title of the archetypal Renaissance man, along with his rival and fellow Florentine Medici client, Leonardo da Vinci. - Nicola Pisano (also called "Niccolo Pisano", "Nicola de Apulia" or "Nicola Pisanus"; c. 1220/1225 c. 1284) was an Italian sculptor whose work is noted for its classical Roman sculptural style. Pisano is sometimes considered to be the founder of modern sculpture. - Bologna (; ) is the largest city (and the capital) of the Emilia-Romagna Region in Northern Italy. It is the seventh most populous city in Italy, located in the heart of a metropolitan area (officially recognized by the Italian government as a "citta metropolitana") of about one million. - A crystal or crystalline solid is a solid material whose constituents (such as atoms, molecules, or ions) are arranged in a highly ordered microscopic structure, forming a crystal lattice that extends in all directions. In addition, macroscopic single crystals are usually identifiable by their geometrical shape, consisting of flat faces with specific, characteristic orientations. The scientific study of crystals and crystal formation is known as crystallography. The process of crystal formation via mechanisms of crystal growth is called crystallization or solidification. - Saint Dominic, also known as Dominic of Osma and Dominic of Caleruega, often called Dominic de Guzman and Domingo Felix de Guzman (August 8, 1170 August 6, 1221), was a Castilian priest and founder of the Dominican Order. Dominic is the patron saint of astronomers. - Limestone is a sedimentary rock, composed mainly of skeletal fragments of marine organisms such as coral, forams and molluscs. Its major materials are the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO). - The statue of St. Petronius ( 1494 -- 1495 ) was created by Michelangelo out of marble . Its height is 64 cm. It is situated in the Basilica of San Domenico , Bologna . Its subject is Saint Petronius , bishop of Bologna . - Leonardo di ser Piero da Vinci (15 April 14522 May 1519), more commonly Leonardo da Vinci or simply Leonardo, was an Italian polymath whose areas of interest included invention, painting, sculpting, architecture, science, music, mathematics, engineering, literature, anatomy, geology, astronomy, botany, writing, history, and cartography. He has been variously called the father of palaeontology, ichnology, and architecture, and is widely considered one of the greatest painters of all time. Sometimes credited with the inventions of the parachute, helicopter and tank, he epitomised the Renaissance humanist ideal. - In art history, High Renaissance is the period denoting the apogee of the visual arts in the Italian Renaissance. The High Renaissance period is traditionally taken to begin in the 1490s, with Leonardo's fresco of the Last Supper in Milan and the death of Lorenzo de' Medici in Florence, and to have ended in 1527 with the sacking of Rome by the troops of Charles V. This term was first used in German (Hochrenaissance) in the early nineteenth century, and has its origins in the "High Style" of painting and sculpture described by Johann Joachim Winckelmann. Over the last twenty years, use of the term has been frequently criticized by academic art historians for oversimplifying artistic developments, ignoring historical context, and focusing only on a few iconic works. - Northern Italy is a cultural and geographical region, without any administrative purpose, used to indicate the northern part of the Italian state, also informally referred as "Il Nord", "Settentrione" or "Alta Italia". It consists of 8 regions in northern Italy: Aosta Valley, Piedmont, Liguria, Lombardy, Emilia-Romagna, Veneto, Friuli-Venezia Giulia, Trentino-Alto Adige/Sudtirol. According to the 2011 census, its population was 27,213,372. For statistic purposes, the Istituto Nazionale di Statistica (ISTAT) uses the term Northwest Italy and Northeast Italy for identifying two of the five statistical regions in its reporting. These same subdivisions are used to demarcate first level Nomenclature of Territorial Units for Statistics (NUTS) regions ("NUTS 1 regions") within the European Union, and the Italian constituencies for the European Parliament. - The Renaissance was a period in European history, from the 14th to the 17th century, regarded as the cultural bridge between the Middle Ages and modern history. It started as a cultural movement in Italy in the Late Medieval period and later spread to the rest of Europe, marking the beginning of the Early Modern Age. - The Arca di San Domenico (Ark of Saint Dominic) is a monument containing the remains of Saint Dominic. It is located in Dominics Chapel in the Basilica of San Domenico in Bologna, Italy. What is the relationship between 'st. petronius ' and 'sculpture'?
