Rose window is often used as a generic term applied to a circular window, but is especially used for those found in Gothic cathedrals and churches. The windows are divided into segments by stone mullions and tracery. The term rose window was not used before the 17th century and comes from the English flower name rose.

The name "wheel window" is often applied to a window divided by simple spokes radiating from a central boss or opening, while the term "rose window" is reserved for those windows, sometimes of a highly complex design, which can be seen to bear similarity to a multi-petalled rose. Rose windows are also called "Catherine windows" after Saint Catherine of Alexandria, who was sentenced to be executed on a spiked breaking wheel. A circular window without tracery such as are found in many Italian churches, is referred to as an ocular window or oculus.

Louis II (825 – 12 August 875), sometimes called the Younger, was the king of Italy and emperor of the Carolingian Empire from 844, co-ruling with his father Lothair I until 855, after which he ruled alone.

Louis's usual title was imperator augustus ("august emperor"), but he used imperator Romanorum ("emperor of the Romans") after his conquest of Bari in 871, which led to poor relations with the Eastern Roman Empire. He was called imperator Italiae ("emperor of Italy") in West Francia while the Byzantines called him Basileus Phrangias ("Emperor of Francia").

A Requiem (Latin: rest) or Requiem Mass, also known as Mass for the dead (Latin: Missa pro defunctis) or Mass of the dead (Latin: Missa defunctorum), is a Mass of the Catholic Church offered for the repose of the souls of the deceased, using a particular form of the Roman Missal. It is usually celebrated in the context of a funeral (where in some countries it is often called a Funeral Mass).

Musical settings of the propers of the Requiem Mass are also called Requiems, and the term has subsequently been applied to other musical compositions associated with death, dying, and mourning, even when they lack religious or liturgical relevance.

The Cult of Reason (French: Culte de la Raison) was France's first established state-sponsored atheistic religion, intended as a replacement for Christianity during the French Revolution. After holding sway for barely a year, in 1794 it was officially replaced by the rival deistic Cult of the Supreme Being, promoted by Robespierre. Both cults were officially banned in 1802 by Napoleon Bonaparte with his Law on Cults of 18 Germinal, Year X.

Painted glass refers to two different techniques of decorating glass, both more precisely known by other terms. Firstly, and more correctly, it means enamelled glass, normally relatively small vessels which have been painted with preparations of vitreous enamel, and then fixed by a light firing to melt them and fuse them to the glass surface.

Secondly it refers to stained glass, used for windows. Here the design is made up using sheets of coloured glass, cut to shape and held in place by lead. The painting is the final stage, typically only in black. The paint is usually not fused to the flat glass by firing, but if it is, it is still called "stained glass".

Caspar Hedio, also written as Kaspar Hedio, Kaspar Heyd, Kaspar Bock or Kaspar Böckel (Ettlingen, 1494 - Strasbourg, 17 October 1552) was a German historian, theologian and Protestant reformer.

He was born into a prosperous family and attended a famous school in Pforzheim. In 1513. he began his studies in Fribourg and later studied theology in Basel, where he received his degree in 1519. At that time, he began his relationship with Ulrich Zwingli and corresponded with Martin Luther. He took his doctorate in Mainz and obtained a position as a preacher at the Strasbourg Cathedral in 1523. His Protestant convictions were made clear when he married Margarete Trenz.

The Neustadt (German for New Town) is a district of Strasbourg, Bas-Rhin, France. In 2017, the heart of the district was listed as a World Heritage Site by UNESCO, as an extension of the site including the older city centre (Grande Île) and Strasbourg Cathedral. The district is a unique example of city planning, merging the Haussmannian model with elements of German architecture and urban planning.

Aside from the Imperial Quarter of Metz, the Neustadt district of Strasbourg contains the most complete and best-preserved examples of urbanism under the German Empire. In Germany itself, the comparable districts of such cities often suffered the bombardment by Allied forces in the Second World War.
