What is a short summary of the play, A Portrait of the Artist as a Filipino, from the story collection, The Woman Who Had Two Navels?

A Portrait of the Artist as a Filipino is a play in three scenes that traces the disintegration, yet ultimate reunification, of the Marasigan family in a time leading up to the devasting effects of World War II. The patriarch of the Marasigan family, Don Lorenzo, was once a sought after painter who, in his self-prescribed hermitage, has produced one last masterful painting which becomes an enormous source of tension in the family as he refuses to sell it, and two of his daughters are enlisted to protect it against their more greedy siblings.
