When this triptych was first exhibited at the end of the war in 1945, it secured Bacon’s reputation. The title relates these horrific beasts to the saints traditionally portrayed at the foot of the cross in religious painting. Bacon even suggested he had intended to paint a larger crucifixion beneath which these would appear.He later related these figures to the Eumenides – the vengeful furies of Greek myth, associating them within a broader mythological tradition. Typically, Bacon drew on a range of sources for these figures, including a photograph purporting to show the materialisation of ectoplasm and the work of Pablo Picasso.
