This article proposes that Federico Garcia Lorca is likely to have suffered from a relatively mild form of dyslexia, using documentation from his biography and autograph manuscripts. A parallel study of William Butler Yeats, whose dyslexia is well attested, provides corroboration and highlights many similarities in their experiences and difficulties. Dyslexia may also have had a repercussion on their literary output: relevant studies of Yeats focus on orality, folklore and visual imagery; similar features are found in Lorca's work, as well as mirror imagery and reciprocal metaphors, where the transposition of tenor and vehicle recalls the phenomenon of metathesis that is a frequent indicator of dyslexia.
