Källunge church (Källunge kyrka) is a church in the island-bishopric of Visby on Gotland. The church is richly decorated with reliefs and frescoes. The frescoes are important evidence of the strong Byzantine influence on Swedish art of the 12th and 13th centuries. An early depiction of a nyckelharpa is found in a relief dating from circa 1350 on one of the gates of the church.
The church gives its name to the Källunge codex (Latin Codex Kellungensis) a 1622 collection of choral music by Philipp Dulichius, Melchior Vulpius, Gregor Aichinger, Nicolaus Zangius,Hieronymus Praetorius, Hans Hassler, Jacobus Gallus, Johann Walter, Dominique Phinot, Orlando di Lasso, and Johann Bahr among others. The collection was discovered in 1913, though only the alto part is extant. 100 of the 315 pieces have been identified from other collections.References:
The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
