Cumae was an ancient city of Magna Graecia on the coast of the Tyrrhenian Sea. Founded by settlers from Euboea in the 8th century BC, Cumae was the first Greek colony on the mainland of Italy and the seat of the Cumaean Sibyl. It spread its influence throughout the area over the 7th and 6th centuries BC, gaining sway over Puteoli and Misenum and, thereafter, founding Neapolis (Naples) in 470 BC.
The Greek period at Cumae came to an end in 421 BC, when the Oscans broke down the walls and took the city, ravaging the countryside. Some survivors fled to Neapolis. Cumae came under Roman rule with Capua and in 338 was granted partial citizenship, a civitas sine suffragio. In the Second Punic War, in spite of temptations to revolt from Roman authority, Cumae withstood Hannibal's siege.
The early presence of Christianity in Cumae is shown by the 2nd-century work The Shepherd of Hermas, in which the author tells of a vision of a woman, identified with the church, who entrusts him with a text to read to the presbyters of the community in Cuma. At the end of the 4th century, the temple of Zeus at Cumae was transformed into a Christian basilica.
Under Roman rule, 'quiet Cumae' slumbered until the disasters of the Gothic Wars (535–554), when it was repeatedly attacked, as the only fortified city in Campania aside from Neapolis: Belisarius took it in 536, Totila held it, and when Narses gained possession of Cumae, he found he had won the whole treasury of the Goths. In 1207, forces from Naples, acting for the boy-King of Sicily, destroyed the city and its walls, as the stronghold of a nest of bandits.
The seaward side of the large rise on which Cumae was built was used as a bunker and gun emplacement by the Germans during World War II.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
