In the context of this artwork, explain the Don Sebastián de Morra of the Subject.
Sebastián de Morra was acquired by King Philip IV in 1643 from his younger brother Cardinal Infante Fernando. He was then given over to Prince Baltasar Carlos until the prince's death in 1646 De Morra's job was to keep the prince entertained with humor. Following the death of Prince Carlos, De Morra died in October 1649 after six years of service to the court. An analysis of the canvases on which portraits of De Morra and Philip IV were painted, conducted by the Thread Count Automation Project, lead to the conclusion that they were both painted from the same piece of cloth. This conclusion revealed that De Morra's portrait was painted in Fraga, along with Philip's portrait.
