Ang died last May 9 from a lingering illness at the St. Lukes Medical Center in Quezon City.
Born in 1931 in Davao City to Chinese-Filipino parents Vicente Ang and Chin Lim, Ang grew up in relative poverty.
He took up fine arts at the University of Sto. Tomas, where he studied under a number of Filipino masters.
Among them were Vicente Manansala, who was to become a life-long friend and mentor.
Ang became known for his graphic depiction of human suffering, with the crucifixion being a frequent theme in his paintings.
He was named National Artist for the Visual Arts by the National Commission for Culture and the Arts in 2001. Aurea Calica
