... pulvis et umbra sumus

[We] are but dust and shadow

Horace's Ode 7 from Book 4 of the Odes

I'll admit I was after a succinct quote to draw attention to the shadows past and present on the above image.
I found a short "quote" displaced of context and probably twisted slightly to fit
popular demand.
Despite having a disjointed and dysfunctional education, I do like to know where the quotes I use come from ... Having never knowingly read anything of his, I think I'll be reading (or attempting to) more Horace.
