Prince Rupert is the key character in the King Crimson song Lizard from their 1970 album of the same name. The 23-minute suite includes several sections, one named Prince Rupert Awakes and another The Battle of Glass Tears (an artistic reference to the battle of Naseby) in turn including a sub-section called Prince Rupert's Lament.
Rupert was born at Amberg in the Upper Palatinate, the son of Elector Palatine Rupert II and Beatrice of Aragon, daughter of King Peter II of Sicily. Rupert's great-granduncle was the Wittelsbach emperor Louis IV. He was raised at the Dominican Liebenau monastery near Worms, where his widowed grandmother Irmengard of Oettingen lived as a nun.
