In the Palaeolithic period, human beings had felt a disturbing kinship with the animals that they hunted and killed. They expressed their inchoate distress in the rituals of sacrifice, which honoured the beasts which laid down their lives for the sake of humanity. In Guernica, humans and animals, both victims of indiscriminate, heedless slaughter, lie together in a mangled heap, the screaming horse inextricably entwined with the decapitated human figure. Recalling the women at the foot of the cross in countless depictions of Jesus's crucifixion, two women gaze at the wounded horse in sorrowful empathy with its pain.
