Machado wrote «A un olmo seco» in Soria, in 1912, while his young wife Leonor was dying. An old elm, split by lightning and half rotten, has put out a few green leaves with the April rains and May sun, and the poet stops before that faint sign of life in something almost dead.
The poem lists every ending that awaits the tree — the axe, the fire, the wind, the woodworm — and still it keeps to the new shoot. In the final turn, so quiet it nearly slips past, the elm becomes hope: the poet writes the miracle in his notebook «before you are felled», himself also waiting for «another miracle of spring». Leonor died that summer.
The verse is kept in Spanish. Translating it in passing would replace the work with a paraphrase of it.
