Choral music trivia

[Occulus]

Name this choral piece of music by reading the lyrics:

Cliffs that rise a thousand feet, without a break
Lake the stretches a hundred miles, without a wave
Sands that are white throughout the year, without a stain
Pine tree woods, winter and summer, evergreen.

Streams that forever flow and flow and flow, without a pause.
Trees that for twenty thousand years, your vows have kept.

You have suddenly healed the pain of a traveler's heart
And moved his brush to write a new song.

WHAT IS THIS CALLED?

Here's a hint: it was written in the 4th century. And it's actually a poem. (EAT it, you silly people in the current poetry thread who don't like poetry! PBLLLLLT!!!!! :) )

Anyone? Bueller?

1. That's not "Das Lied von der Erde", is it??

...which I have to confess is something I haven't explored yet. I'm just now "getting" the final movement of the 2nd symphony 15 years after first hearing it, and now it blows me away every time.

(Not sure if I'll ever get #8. Haven't found any "hooks" in there yet.)

2. Nope.

Another hint: it's a capella.
