Wanderer, your footsteps are
the road, and nothing else;
wanderer, there is no road,
the road is made by walking.
Walking makes the road,
and on glancing behind
one sees the path
that he will never trod again.
Wanderer, there is no road—
Just foam in the sea.

– Antonio Machado, “Proverbios y cantares XXIX” [Proverbs and Songs 29], Campos de Castilla (1912); trans. Betty Jean Craige in Selected Poems of Antonio Machado (Louisiana State University Press, 1979)
