"A Nativity" by W.B. Yeats
What woman hugs her infant there?
Another star has shot an ear.
What made the drapery glisten so?
Not a man but Delacroix.
What made the ceiling waterproof?
Landor's tarpaulin on the roof
What brushes fly and moth aside?
Irving and his plume of pride.
What hurries out the knaye and dolt?
Talma and his thunderbolt.
Why is the woman terror-struck?
Can there be mercy in that look?
I want to know who Landor and Irving and Talma are and Google isn't helping me figure it out. Any ideas?
