What metaphors are used in Gacela of the Dark Death by Federico Garcia Lorca?

The poem opens with an arresting metaphor that establishes the rhythm of its lines. The death that the speaker desires is not found in earthly cemeteries, for what he expresses in his tamarit garden is an unearthly anguish. The "sleep" that is desired is a sleep that is not temporal or terrestrial; it is of Lorca's idiosyncratic world, it is a "sleep of apples."
