Gold Leaf on a Halo

Also takes a lot of craft.
Someone has to mine the gold.
Try that, sometimes. Purified,

The gold has to be beaten
Into salable gold leaf.
You have to paint the halo.

You have to apply the leaf.
Do you know of any saints
Of angelic halo gold,

Any gods who patronize
The craft of patching gold leaf?
Surely someone’s thought up one.

Don’t tell us genius isn’t magic,
Needs no visits from the muse.
Everyone gets the visit,

But unless you’re in the shop,
Working hard, needing a break,
It’s the knock you might refuse.
