Attempted Ekphrastic Eulogy for Childhood

I found our Thursday afternoon;
They put it in a frame
Between these bars of slanting light
And someone else's fame.

Our waning sunlight was this pale;
Our skies, this aching teal.
In shadows from the swaying trees
Our view was this unreal.

See, here- the colors imitate
The blush of desperation.
How could an artist know the shade
Of our anticipation?

Were we waiting for the sun to set
Or for our lives to start?
We were growing up beneath those trees
And living through our hearts.

A picture does no justice to
The things we've left behind.
But Thursday, in its loveliness
Is here for us, enshrined.

Ekphrasis:
Technical term of ancient rhetoric: teachers of rhetoric defined it as a vivid description intended to bring the subject before the mind’s eye of the listener.
