Behind the veil

I was in London when a gust of unexpected wind blew back the veil of a woman and by chance I saw her face.
Unexpected

The veil lifted 

By God’s breath 
A gasp of that unseen
Beauty glimpsed
Mystery  revealed
Then lost again
To a fluttering caprice
Of fabric in breeze.
Was that a taste of truth
A brief scent of hope
There, then lost, 
Some instant so real
To hold, to mold, 
A shard of memory
Sharp in focus
But soon fading
In the vapors of time 
And long-held belief.
