Similarly, a "Chevalier Vert" appears in the Chronicle of Ernoul during the recollection of events following the capture of Jerusalem in 1187; here, he is identified as a Spanish knight who earned this nickname from the Muslims due to his eccentric apparel.See the "Chronique d’Ernoul et de Bernard le Trésorier", edited by L. de Mas Latrie, Paris 1871, p. 237.
