James Stanfield‘s photograph of this Roman aqueduct (in Spain) called to mind one of my favorite Bob Dylan songs.


by Bob Dylan

Oh, the hours that I spent inside the Coloseum,

Dodging lions and wasting time.

Oh, those mighty kings of the jungle 

I could hardly stand to see ’em

Yes, it sure has been a long, hard climb

Train wheels runnin’ through the back of my memory

When I ran on the hilltop following a pack of wild geese.

Some day everything is going to sound like a rhapsody

When I pain my masterpiece. 

Listen to The Band (with Levon Helm — RIP — singing) perform the song on YouTube.
