History of Sweden between 400 AD - 539 AD
The Migration Period was in general a period of intensified human migration in Europe from about 400 to 800 AD. The changes in material culture marking the start of the Migration Period appear to coincide with the arrival of the Huns on the continental stage. A brief tumultuous phase ensued during which Western Rome collapsed and Eastern Rome held the barbarians at bay only through enormous peace payments. As a consequence, the Scandinavian elite of the time was inundated with gold. It was used to produce some very fine goldsmith work including filigree collars and bracteate pendants. The memory of this Golden Age reverberates through all the main early Germanic poetry cycles, including Beowulf and the Niebelungenlied.
Another feature of the Migration Period that had far-reaching consequences was the development of the first Scandinavian animal art. Inspired by provincial Roman chip-carved belt mounts decorated with lions and dolphins along the edges, Scandinavian artisans of the Migration Period developed first the Nydam Style, and then the highly abstract and sophisticated Style I from c. 450 onward.
The Migration Period was long believed to have been a time of crisis and devastation in Scandinavia. In recent decades, however, scholarship has gravitated to the view that the period was in fact one of prosperity and glorious elite culture, but that it ended with a severe crisis, possibly having to do with the AD 535-536 atmospheric dust event and the concomitant famine.
The Mosque–Cathedral of Córdoba, also known as the Great Mosque of Córdoba and the Mezquita is regarded as one of the most accomplished monuments of Moorish architecture.
According to a traditional account, a small Visigoth church, the Catholic Basilica of Saint Vincent of Lérins, originally stood on the site. In 784 Abd al-Rahman I ordered construction of the Great Mosque, which was considerably expanded by later Muslim rulers. The mosque underwent numerous subsequent changes: Abd al-Rahman II ordered a new minaret, while in 961 Al-Hakam II enlarged the building and enriched the Mihrab. The last of such reforms was carried out by Almanzor in 987. It was connected to the Caliph"s palace by a raised walkway, mosques within the palaces being the tradition for previous Islamic rulers – as well as Christian Kings who built their palaces adjacent to churches. The Mezquita reached its current dimensions in 987 with the completion of the outer naves and courtyard.
In 1236, Córdoba was conquered by King Ferdinand III of Castile, and the centre of the mosque was converted into a Catholic cathedral. Alfonso X oversaw the construction of the Villaviciosa Chapel and the Royal Chapel within the mosque. The kings who followed added further Christian features, such as King Henry II rebuilding the chapel in the 14th century. The minaret of the mosque was also converted to the bell tower of the cathedral. It was adorned with Santiago de Compostela"s captured cathedral bells. Following a windstorm in 1589, the former minaret was further reinforced by encasing it within a new structure.
The most significant alteration was the building of a Renaissance cathedral nave in the middle of the expansive structure. The insertion was constructed by permission of Charles V, king of Castile and Aragon. Artisans and architects continued to add to the existing structure until the late 18th century.
The building"s floor plan is seen to be parallel to some of the earliest mosques built from the very beginning of Islam. It had a rectangular prayer hall with aisles arranged perpendicular to the qibla, the direction towards which Muslims pray. The prayer hall was large and flat, with timber ceilings held up by arches of horseshoe-like appearance.
In planning the mosque, the architects incorporated a number of Roman columns with choice capitals. Some of the columns were already in the Gothic structure; others were sent from various regions of Iberia as presents from the governors of provinces. Ivory, jasper, porphyry, gold, silver, copper, and brass were used in the decorations. Marvellous mosaics and azulejos were designed. Later, the immense temple embodied all the styles of Morisco architecture into one composition.
The building is most notable for its arcaded hypostyle hall, with 856 columns of jasper, onyx, marble, granite and porphyry. These were made from pieces of the Roman temple that had occupied the site previously, as well as other Roman buildings, such as the Mérida amphitheatre. The double arches were an innovation, permitting higher ceilings than would otherwise be possible with relatively low columns. The double arches consist of a lower horseshoe arch and an upper semi-circular arch.
