The poems of the old century hold their magic. “Cemetery in Snow” by Xavier Villaurrutia is such a poem. You can think about the poem several ways but because the subject is so singular it is trapped in the glass of its making. Shake it and the letters will settle back in some insensible way, burying the cemetery just so. The poem was probably not so much a matter of writing as of polishing glass, clarifying silence, making each different letter fall the same way.
