CathedralA cathedral is a church that contains the cathedra of a bishop, thus serving as the central church of a diocese, conference, or episcopate. Churches with the function of "cathedral" are usually specific to those Christian denominations with an episcopal hierarchy, such as the Catholic, Eastern Orthodox, Anglican, and some Lutheran churches.
Illuminated manuscriptAn illuminated manuscript is a formally prepared document where the text is decorated with flourishes such as borders and miniature illustrations. Often used in the Roman Catholic Church for prayers, liturgical services and psalms, the practice continued into secular texts from the 13th century onward and typically include proclamations, enrolled bills, laws, charters, inventories and deeds. The earliest extant illuminated manuscripts come from the Kingdom of the Ostrogoths and the Eastern Roman Empire and date from between 400 and 600 CE.
GrisailleGrisaille (ɡrᵻˈzaɪ or ɡrᵻˈzeɪl; grisaille ɡʁizaj, from gris 'grey') is a painting executed entirely in shades of grey or of another neutral greyish colour. It is particularly used in large decorative schemes in imitation of sculpture. Many grisailles include a slightly wider colour range. A grisaille may be executed for its own sake, as an underpainting for an oil painting (in preparation for glazing layers of colour over it) or as a model from which an engraver may work (as was done by Rubens and his school).
GlassblowingGlassblowing is a glassforming technique that involves inflating molten glass into a bubble (or parison) with the aid of a blowpipe (or blow tube). A person who blows glass is called a glassblower, glassmith, or gaffer. A lampworker (often also called a glassblower or glassworker) manipulates glass with the use of a torch on a smaller scale, such as in producing precision laboratory glassware out of borosilicate glass.
Perpendicular GothicPerpendicular Gothic (also Perpendicular, Rectilinear, or Third Pointed) architecture was the third and final style of English Gothic architecture developed in the Kingdom of England during the Late Middle Ages, typified by large windows, four-centred arches, straight vertical and horizontal lines in the tracery, and regular arch-topped rectangular panelling. Perpendicular was the prevailing style of Late Gothic architecture in England from the 14th century to the 17th century.
Venetian glassVenetian glass (vetro veneziano) is glassware made in Venice, typically on the island of Murano near the city. Traditionally it is made with a soda–lime "metal" and is typically elaborately decorated, with various "hot" glass-forming techniques, as well as gilding, enamel, or engraving. Production has been concentrated on the Venetian island of Murano since the 13th century. Today Murano is known for its art glass, but it has a long history of innovations in glassmaking in addition to its artistic fame—and was Europe's major center for luxury glass from the High Middle Ages to the Italian Renaissance.
Gloucester CathedralGloucester Cathedral, formally the Cathedral Church of St Peter and the Holy and Indivisible Trinity, in Gloucester, England, stands in the north of the city near the River Severn. It originated with the establishment of a minster, Gloucester Abbey, dedicated to Saint Peter and founded by Osric, King of the Hwicce, in around 679. The subsequent history of the church is complex; Osric's foundation came under the control of the Benedictine Order at the beginning of the 11th century and in around 1058, Ealdred, Bishop of Worcester, established a new abbey "a little further from the place where it had stood".
DonatelloDonato di Niccolò di Betto Bardi (1386 – 13 December 1466), better known as Donatello (,dQn@'tElou donaˈtɛllo), was an Italian sculptor of the Renaissance period. Born in Florence, he studied classical sculpture and used his knowledge to develop an Early Renaissance style of sculpture. He spent time in other cities, where he worked on commissions and taught others; his periods in Rome, Padua, and Siena introduced to other parts of Italy the techniques he had developed in the course of a long and productive career.
Borosilicate glassBorosilicate glass is a type of glass with silica and boron trioxide as the main glass-forming constituents. Borosilicate glasses are known for having very low coefficients of thermal expansion (≈3 × 10−6 K−1 at 20 °C), making them more resistant to thermal shock than any other common glass. Such glass is subjected to less thermal stress and can withstand temperature differentials without fracturing of about . It is commonly used for the construction of reagent bottles and flasks, as well as lighting, electronics, and cookware.
MedievalismMedievalism is a system of belief and practice inspired by the Middle Ages of Europe, or by devotion to elements of that period, which have been expressed in areas such as architecture, literature, music, art, philosophy, scholarship, and various vehicles of popular culture. Since the 17th century, a variety of movements have used the medieval period as a model or inspiration for creative activity, including Romanticism, modern paganism, the Gothic revival, the pre-Raphaelite and arts and crafts movements, and neo-medievalism (a term often used interchangeably with medievalism).
