Amba Geshen

Amba Geshen is the name of a mountain in northern Ethiopia. It is in Ambassel, South Wollo Zone of the Amhara Region, northwest of Dessie, at a latitude and a longitude of . Part of Ambassel woreda, Amba Geshen is one of the mountains of Ethiopia where most of the male heirs to the Emperor of Ethiopia were interned, usually for life. It was the second of the three such mountains, or "amba", said to have been used for this purpose, the other two being Debre Damo and Wehni.
History.
From some undetermined time, it was the practice that when the Ethiopian emperor assumed the throne, his brothers and other male relatives would be taken to a royal prison, where they would henceforth live until either they were called forth to become the new emperor or they died. Some traditions state this began during the Zagwe dynasty, others even earlier; the first certain mention of the practice was during the reign of Jin Asgad, who confined his brothers and his own sons to Amba Geshen.
The use Amba Geshen as a prison was ended by Emperor Na'od, but Manoel de Almeida mentions that "those who were there before" were guarded until the reign of Emperor Gelawdewos, when only the descendants of Emperor Takla Maryam continued to be kept under watch because of their treachery against Emperor Baeda Maryam I.
Because it was a natural fortress, the Emperors also kept the imperial treasury there even after it was no longer a royal prison. The Muslims, under Ahmed Gragn, made several attempts to capture Amba Geshen: the "Futuh al-Habasha" describes the first (in November 1531) and second (in 1533); his final attempt in 1540 was successful, and he put the entire garrison and inhabitants to death. Thomas Pakenham notes that contemporary Ethiopians believe that the True Cross was buried atop Amba Geshen by St Helena of Constantinople.
Although the first European to mention Amba Geshen was Francisco Álvares, who witnessed an escaped prince being returned to Amba Geshen, the earliest European to accurately describe Amba Geshen was Almeida, who states it is
Almeidez further writes that on top there was a natural pool and spring for water, and covered by "kosso" and "zegba" brush and wild cedars. He mentions two churches: Egzyabeher Ab, built by Emperor Lalibela, and Tekle Maryam, begun by Emperor Na'od but completed by his son, Lebna Dengel, which survived Ahmed Gragn's ravages. However, when Pakenham visited Amba Geshen in 1955, he found that both churches had been rebuilt with tin roofs.
English literature.
Another inaccurate account of Amba Geshen, called Mount Amara, was published in "Purchas, His Pilgrimage", which was believed by Pakenham to have inspired John Milton's description of Paradise in "Paradise Lost", and later Samuel Taylor Coleridge's poem "Kubla Khan".
In Samuel Johnson's "Rasselas", the main character is a prince of Ethiopia who is interned in a mountain sanctuary called the "Happy Valley". To explore the world and find his own happiness, he escapes. Johnson's account was based on the travel account of Jerónimo Lobo.
