De Ceremoniis
The Chrysotriklinos (, "golden reception hall", cf. "triclinium"), Latinized as Chrysotriclinus or Chrysotriclinium, was the main reception and ceremonial hall of the Great Palace of Constantinople from its construction, in the late 6th century, until the 10th century. Its appearance is known only through literary descriptions, chiefly the 10th-century "De Ceremoniis", a collection of imperial ceremonies, but, as the chief symbol of imperial power, it inspired the construction of Charlemagne's Palatine Chapel in Aachen.
