What music of Popol Vuh is actually used for this film?

Information below is based on the findings by David Goodine (Toronto). 

In order of appearance:

1. 'Oh wie nah ist der Weg hinab'

Appears to be the same version as on the 'Letzte Tage - Letzte Nachte'- album

2. Unknown piece.

Does not appear on any Popol Vuh release.

3. 'Engel der Gegenwart'

Brief excerpt from the first part of this tune, the only part of the 'Herz aus Glas'-album to even remotely appear on the actual film

soundtrack. And it sounds like a different version as well!

4. 'In deine Hände'

Same as on the 'Letzte Tage.- Letzte Nächte’- album as far as I can tell.

5. 'Oh wie nah ist der Weg hinab' (reprise)

Slower version.

6. 'Oh wie nah ist der Weg hinab' (reprise)

Slower version. These versions sound slower than the original, but are in the same key, so I don't think Herzog slowed the tape down,

intentionally, as he did for two Popol Vuh songs on the 'Fitzcaraldo'-soundtrack.

7. 'Engel der Gegenwart' (reprise)

Same as above, and therefore different from the 'Herz aus Glas'-album.
