CtesiphonCtesiphon (ˈtɛsɪfɒn ; Middle Persian: 𐭲𐭩𐭮𐭯𐭥𐭭 tyspwn or tysfwn; تیسفون; Κτησιφῶν, ktɛːsiphɔ̂ːn; ܩܛܝܣܦܘܢ) was an ancient city, located on the eastern bank of the Tigris, about southeast of present-day Baghdad. Ctesiphon served as a royal capital of the empires in the Parthian and Sasanian eras for over eight hundred years. Ctesiphon was capital of the Sasanian Empire from 226–637 until the Muslim conquest of Persia in 651 AD. Ctesiphon developed into a rich commercial metropolis, merging with the surrounding cities along both shores of the river, including the Hellenistic city of Seleucia.
Christianisation of the Germanic peoplesThe Germanic peoples underwent gradual Christianization in the course of late antiquity and the Early Middle Ages. By AD 700, England and Francia were officially Christian, and by 1100 Germanic paganism had also ceased to have political influence in Scandinavia. Germanic peoples began entering the Roman Empire in large numbers at the same time that Christianity was spreading there. The connection of Christianity to the Roman Empire was both a factor in encouraging conversion as well as, at times, a motive for persecuting Christians.
Clerical celibacyClerical celibacy is the requirement in certain religions that some or all members of the clergy be unmarried. Clerical celibacy also requires abstention from deliberately indulging in sexual thoughts and behavior outside of marriage, because these impulses are regarded as sinful. Within the Catholic Church, clerical celibacy is mandated for all clergy in the Latin Church except in the permanent diaconate.
BroochA brooch (ˈbroʊtʃ, also USˈbruːtʃ) is a decorative jewelry item designed to be attached to garments, often to fasten them together. It is usually made of metal, often silver or gold or some other material. Brooches are frequently decorated with enamel or with gemstones and may be solely for ornament or serve a practical function as a clothes fastener. The earliest known brooches are from the Bronze Age. As fashions in brooches changed rather quickly, they are important chronological indicators.
GalataGalata is the former name of the Karaköy neighbourhood in Istanbul, which is located at the northern shore of the Golden Horn. The district is connected to the historic Fatih district by several bridges that cross the Golden Horn, most notably the Galata Bridge. The medieval citadel of Galata was a colony of the Republic of Genoa between 1273 and 1453. The famous Galata Tower was built by the Genoese in 1348 at the northernmost and highest point of the citadel. Galata is now a quarter within the district of Beyoğlu in Istanbul.
CherusciThe Cherusci were a Germanic tribe that inhabited parts of the plains and forests of northwestern Germany in the area of the Weser River and present-day Hanover during the first centuries BC and AD. Roman sources reported they considered themselves kin with other Irmino tribes and claimed common descent from an ancestor called Mannus. During the early Roman Empire under Augustus, the Cherusci first served as allies of Rome and sent sons of their chieftains to receive Roman education and serve in the Roman army as auxiliaries.
Porphyry (geology)Porphyry (ˈpɔrfəri ) is any of various decorative granites or igneous rocks with coarse-grained crystals such as feldspar or quartz dispersed in a fine-grained silicate-rich, generally aphanitic matrix or groundmass. The larger crystals are called phenocrysts. In its non-geologic, traditional use, the term porphyry usually refers to the purple-red form of this stone, valued for its appearance, but other colours of decorative porphyry are also used such as "green", "black" and "grey".
Tur AbdinTur Abdin (طور عبدين, Tor, Turabdium, Ṭūr ʿAḇdīn) is a hilly region situated in southeast Turkey, including the eastern half of the Mardin Province, and Şırnak Province west of the Tigris, on the border with Syria and famed since Late Antiquity for its Christian monasteries on the border of the Roman Empire and the Sasanian Empire. The area is a low plateau in the Anti-Taurus Mountains stretching from Mardin in the west to the Tigris in the east and delimited by the Mesopotamian plains to the south.
Edict of MilanThe Edict of Milan (Edictum Mediolanense; Διάταγμα τῶν Μεδιολάνων, Diatagma tōn Mediolanōn) was the February 313 AD agreement to treat Christians benevolently within the Roman Empire. Western Roman Emperor Constantine I and Emperor Licinius, who controlled the Balkans, met in Mediolanum (modern-day Milan) and, among other things, agreed to change policies towards Christians following the edict of toleration issued by Emperor Galerius two years earlier in Serdica.
TesseraA tessera (plural: tesserae, diminutive tessella) is an individual tile, usually formed in the shape of a square, used in creating a mosaic. It is also known as an abaciscus or abaculus. The oldest known tesserae date to the 3rd millennium BC, discovered in the ancient city of Shahdad in Kerman province, Iran. In early antiquity, mosaics were formed from naturally formed colored pebbles. By roughly 200 BC cut stone tesserae were being used in Hellenistic-Greek mosaics.
