What metaphors are used in Blood Wedding by Federico Garcia Lorca?

The main metaphor of Blood Wedding is an extended allusion to a ritual enactment that, like the play itself, is elemental in Spanish consciousness but reaches beyond nationality toward archetype: the bull fight. The mother tells the Bridegroom that he, like his father before him, is a bull-man, and she calls the Felix family matadors. The
wedding of the Bride and Bridegroom arises, as the handmaidens sing, "like a bull," a bull that is destined to be destroyed by the matador, Leonardo.
