Tirso de Molina: Tamar's Revenge

The story comes from the Second Book of Samuel and tells of the incestuous passion of Amnon, David's eldest son, for his half-sister, Tamar and the subsequent murder of Amnon by his brother Absolom. Amnon's lust is set in the context of complementary passions of ambition and revenge, reflected in Absolom and Tamar respectively.
