ALFREDO ARITCHETA LIONGOREN, born 15 January 1944, is recognized in Philippine contemporary art history as one of the country's earlier abstractionist when this modernist visual vocabulary was assimilated into the country's cultural expressions. He showed experimentation with materials like burlap, rope, sand, and glue which he incorporated into his oil paintings in the mid-1960s. His works are combined abstraction and figuration. He has also been painting on abstract landscapes which explore the medium of paint: oil, acrylic, and watercolor. A multi-awarded artist, Liongoren's calligraphic brushwork paintings infused sensibilities such as intuition and refinement into the works under Philippine abstraction. Liongoren was a recipient of the Thirteen Artist of the Cultural Center of the Philippines in 1972.
