"Louis the Springer (German: Ludwig der Springer), sometimes called Louis the Jumper or Louis the Leaper (died 8 May 1123), was a German nobleman and count in Thuringia from 1080 until his death. Little is known about him, although he is mentioned in many legends. He was a prominent opponent of the Salian emperors Henry IV and Henry V during the Investiture Controversy." -- Wikipedia

"An oriel window is a form of bay window which protrudes from the main wall of a building but does not reach to the ground. Supported by corbels, brackets, or similar cantilevers, an oriel window is most commonly found projecting from an upper floor but is also sometimes used on the ground floor. Oriel windows are seen in Arab architecture in the form of mashrabiya and in Turkish are known as şahnişin or cumba. In Islamic culture, these windows and balconies project from the street-front of a house, providing an area in which women could peer out and see the activities below while remaining invisible." -- Wikipedia
