Hippana was an ancient town of Sicily, mentioned by Polybius as being taken by assault by the Romans in the First Punic War, 260 BCE. Diodorus, in relating the events of the same campaign, mentions the capture of a town called 'Sittana', for which we should in all probability read 'Hippana'. It sat astride the main road from Panormus (modern Palermo) to Agrigentum (modern Agrigento) upon Monte dei Cavalli.
Some manuscripts of Pliny mention the name of Ipanenses in his list of Sicilian towns, where the older editions have Ichanenses. If this reading be adopted, it in all probability refers to the same place as the Hippana of Polybius; but as the reading Ichanenses is also supported by the authority of Stephanus (who notices Ichana as a town of Sicily), the point must be considered doubtful.
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.
