This is a genuine 800 year old Troubadour song, arranged here for solo lyre, & written by Walther Von Der Vogelweide called “Palästinalied”. Here are some interesting details about the song from Wikipedia:
“Palästinalied was written in connection with the Fifth Crusade (1217-1221). Although it is a political-religious propaganda song describing a crusade into the Holy Land, it is atypical for a song of this kind in that it also recognizes the claim of all Abrahamic religions to the Holy Land, although finally asserting that the Christian cause is the “right one” in the last strophe:
Kristen juden und die heiden
jehent daz dis ir erbe sî
got müesse ez ze rehte scheiden
dur die sîne namen drî
al diu werlt diu strîtet her
wir sîn an der rehten ger.
reht ist daz er uns gewer
This strophe can be translated as follows: Christians, Jews and Heathens claim this to be their heritage. God has to assign it in the right way, for His three names. The whole world is coming battling here – our cause is right. It is right that He is granting it to us.”
Despite all the pointless religious intolerance (as the words to this song certainly testify!), and the sheer bloody brutality of the Crusades, at least they resulted some amazing, utterly timeless melodies, like this!
