Moments Aren't All There Is to Time

Music: Vom Himmel hoch, da komm ich her. (BWV 700).
By J.S. Bach. Sequenced by Margareth Greentree at Kunst der Fuge.

Moments aren't all there is to time.
One doesn't travel everywhere by sea.
Stories of days past and futures planned
Have made of time a journey over land,
Epic of plains crossed and mountains climbed.
Retain then, please, both tropes within your mind,
That one the other's firmanent might be.
