The idea of courtly love can be found in a lot of literature of that time , e.g. in works by Geoffrey Chaucer , Dante , Gottfried von Strassburg , Walther von der Vogelweide , Wolfram von Eschenbach , Malory and William Shakespeare . This French tradition spread later to the German MinnesÃ nger , such as Walther von der Vogelweide and Wolfram von Eschenbach .
