The serene Bicha de Balazote—a 2-foot-high, fifth-century B.C. limestone sculpture with a bull’s head and a human’s body—once guarded a tomb. Stone lions, bulls and sphinxes were frequently placed on the tombs of aristocratic Iberians, an ancient people who flourished for about 400 years, from the end of the sixth century B.C. to the early first century B.C. In “Warriors, Wolves and Women,” Spanish art historian Ricardo Olmos tells us what we can learn about the Iberians from their (mostly funerary) art.
